All organisms in the forest Population- Group of relatable monkeys , all Individuals In a single area Organism; ring tailed lemur an Individual living thing Organ system- Nervous system ,nervous system controls Its actions, organs working getter. Organ- made up of, similar cells that performs a specific function tissue Cell-fundamental unit of life Organelle- membrane enclosed structure that performs a specific function Molecule- cluster of small chemical units atoms held together by molecular bond Deoxyribonucleic acid CHI. Matter- anything that occupies space and has mass Element- a substance that canââ¬â¢t be broken down to other substances by ordinary chemical means. We will write a custom essay sample on Bio book outline or any similar topic only for you Order Now 92 elements Compound-two or more different elements combined in a fixed ratio. More common than lone elements. Trace elements- in the body only make up about 0. 04% of your body weight but vital for energy processing. Electrons- two revolve on an orbital(discrete volume of space where E are found) around the nucleus at about the speed of light. Move around the nucleus only at specific energy levels called Electron Shells Protons + Neutrons = Mass # The number of ejectors In an atoms outer valence shell determines Its overall chemical properties. Atomic number-the first number (number of protons) particles and energy. Medical diagnosis and treatment: Used to tag chemicals that accumulate in the body Phosphorous in bones, inject a tracer isotope. PET scanner produces an image of where the radiation collects, Shimmers patient. Deposits of plaque in the brain beta-myeloid show up on PET. This test allows researchers to monitor the effectiveness of new drugs on people. Orbital- 1. Each ring can only have 2 electrons, 2. 2nd and 3rd ring: four orbital, Outer ring can hold 8 3. Number of electrons increases from left to right per. Table Valence Shell- Number of electrons on outermost ring. Determines an atoms. Chemical properties. Valence number; number of additional electrons needed to fill the threshold, bonding capacity Chemical Bonds: two atoms with incomplete tortoiseshells react and donate electrons to complete their outer shells. Covalent Bond; two atoms share one or more pairs of outer shells. TWO or more atoms that share this bond are called Molecule. Electronegative- an toms attraction for shared electrons. Unpopular covalent bonds- electrons shared evenly between atoms. When atoms of a molecule equally pull on electrons. Happens in molecules of same elements. Methane also has a unpopular bond because carbon and hydrogen atoms rant that different. 02, H2O Polar covalent bonds- Molecules with different electromagnetisms attract. The unequal sharing of electrons, pulling shared negatively charges closer to a the more electronegative atom. H2O 0 Oxygen is slightly negative and Hydrogen slightly positive. Unequal sharing of electrons. Polar Molecule- polar covalent bond and V shape molecule. Slightly unequal distribution of charges. Slightly negative points at the V. H2O 0 Slightly positive on hydrogen, points to the O Ion- an atom or molecule with an electrical charge due to gain or loss of one or more electrons. 1 Two ions with opposite charges attract catheter. When the attraction holds together its an Ionic Bond. Salt- sodium chloride Nasal, crystals in nature. Sodium chloride always 1;1 ratio. An Hydrogen Bond- a weaker bond that holds together briefly than separates. The charged regions in each water molecule are attracted to opposite lay charged regions on neighbor molecules. Because the positively charged region in this bond is always a hydrogen atom it gets its name. Each hydrogen of a water molecule can form a hydrogen bond with a nearby partial negative oxygen of another water molecule. Can bond to as many as 4 partners. Heat absorbed when they break, heat is released when they form. When it cools) Overarching Theme: The structures of atoms and molecules determines the way they behave. Reactant- Starting materials to the left of the arrow Product- to the right , results from chemical reaction. Cohesion-the tendency for molecules of the same kid to stick together. The evaporation of water is an upward force on the water within a leaf. Adhesion- the clinging of one substance to another. Counters the downward pull of gravity, water sticking to the veins of a plant. Surface tension- the measure of how difficult it is to break or stretch the surface of a liquid. Hydrogen bonds gig water an unusually high surface tension Evaporative Cooling- When a substance evaporates and the surface of the liquid that mains cools down. The molecules with the greatest energy leave. Solution- A uniform mixture of two or more substances. The dissolving agent is the Solvent (water) and a substance that is dissolved (salt) is the solute. Aqueous Solution- where water is the solvent. How salt mixes with water. The partial negative Oxygen in H2O is attracted to the slightly positive An+ sodium ions and the slightly positive hydrogen ions are attracted to the slightly negative chloride CLC- Dissociate-break apart into ions. Hydrogen ions H+ and Hydroxide OH- re very reactive. Some chemicals contribute H=, some remove. A impound that donates H+ to solutions is Acid- has a higher concentration of H+ them from a solution. More basic solution has higher hydroxide OH- and lower hydrogen H+. PH scale- potential odd hydrogen. O most acidic, 14 most basic. Each unit represents a lox times change. PH 2 has lox more H+ than pH 3. 7 is equal. PH of blood plasma is about 7. 4 Buffers-biological substances that minimize changes in PH. Blood buffers acid more than water. Acid Rain- precipitation with pH lower than 5. Ocean acidification- dissolving CA in seawater lowers oceans PH. CA reacts with water to create carbonic acid. Calcification, how some organism produce shells. Heat- the amount of energy associated with the movement of atoms and molecules in a body of water. Temperature- measures the intensity of the heat. The average speed of molecules rather than the total amount of heat. Chapter 3. The molecules of ce lls (crabs, lipids, proteins, nucleic acid) Variety of polymers makes up for uniqueness of species. Living organisms built from the same 20 amino acids. You read "Bio book outline" in category "Papers" Small molecules common to all are ordered into large molecules which vary from species to species. Carbon is attached to almost all molecules a cell makes and is unparalleled in its ability to form large and complex molecules. Organic Compounds- carbon-based compounds, Carbon has 4 electrons on the valence shell that holds 8, room for 4 covalent bonds. A great connecting point to line up 4 different directions. Hydrocarbons- compounds composed of only hydrogen and carbon. Methane, and propane are hydrocarbon fuels. Carbon skeleton- chain of carbon atoms in an organic molecule. Can be branched or unbranded May include double bonds and some are in rings. Isomers- Compounds with the same formula but different structural arrangements. Some molecules can have the same number of atoms, but have different three emotional shapes because of the location of the double bond. Sometimes harmful effects. One isomer of methamphetamine is the addictive illegal drug. The other is medicine for sinus congestion. The shape of a molecule determines the it functions in the body. Different shapes of isomers result in unique properties and greatly add to diversity of organic molecules. Hydrophilic- water loving, soluble in water. The first 5 functional groups act this way. Hydroxyl, carbonyl, carbonyl, amino, phosphate. Groups, hydroxyl, amino, and phosphate donââ¬â¢t contain Carbon 1 . Hydroxyl- hydrogen atom bonded to oxygen, then binned to carbon skeleton. Alcohols. 2. Carbonyl- carbon atom linked with double bond to oxygen. If carbonyl group is at the end of a carbon skeleton its an allayed. If its within the chain it is called a ketene. 3. Carbonyl- carbon double bond to an oxygen atom and also a hydroxyl group. Carboxylic acids. Acetic acid like vinegar. 4. Amino group-nitrogen bonded to two hydrogen and the carbon skeleton. Iconic compounds with an amino group are called Amines. The building blocks of proteins are called amino acids. They contain an amino and carbonyl group. 5. Phosphate group- phosphorous bonded to 4 oxygen atoms. Compounds with hostage groups are called organic phosphates- involved in energy transfer TAP. 6. Methyl group- Consists of a carbon bonded to three hydrogen. Compounds with methyl groups are called mentholated compounds. Macromolecules- crabs, proteins, nucleic acids might be gigantic, thousands of atoms. Polymers- Chains of smaller molecules. Consists of many identical or similar building blocks. Dehydration Reaction, a reaction that removes a molecule of water. Cells link monomers to make polymers this way. Links two monomers together Hydrolysis- the breaking down of macromolecules, digesting polymers to make monomers available. In digestion, the proteins are broken down into amino acids by hydrolysis, new proteins are formed in your body cells from these monomers in dehydration reactions. Both dehydration and hydrolysis require enzymes- specialized macromolecules that speed of the chemical reaction in cells. Proteins- are built of only 20 amino acids, DNA is built from Just 4 kinds of monomers called Nucleotides Carbohydrate- a class of molecules ranging from small sugar macroeconomics, to large polysaccharide Crab monomers are monsoons ( single sugars) glucose and fructose Disaccharide- cells construct one of these from two incarcerations by dehydration action. Sucrose most common, (glucose linked to fructose) from sugarcane and sugar beets. Maltose also common, beer, malted milk, High fructose corn syrup- the missionaries of sucrose Polysaccharide- are macromolecules, thousands of monomaniacs linked together by dehydration reactions. Glycogen, and cellulose. Starch- Storage polysaccharide in plants of all glucose monomers. Bans from which plant cells gather glucose for energy. Glycogen- animals store glucose this way, a different polysaccharide. Stored in your liver and muscle cells. Cellulose- tough walls that surround the cell, most abundant compound. Not a nutrient for humans because animals canââ¬â¢t hydrology the linkages. The cellulose that phosphorous the body unchanged is called insoluble fiber. Bath tools are mostly cellulose, very hydrophilic absorbs water because of hydroxyl groups. Chitin- another polysaccharide used by insects and crustaceans to build their cells, Both starch and cellulose and polymers of glucose but have different shaped bonds. Starch is for sugar storage, cellulose is a structural polysaccharide that is the main material of the plant cell wall. Lipids- diverse compounds grouped together because of one trait: they donââ¬â¢t mix ell in water. Hydrogen and carbon linked by unpopular covalent bonds. Lipids are Hydrophobic- water fearing Fat- a large lipid made up of smaller molecules: glycerol and fatty acids. Glycerol an local with three carbons, each with a hydroxyl group (OH-). + a hydrocarbon chain (16-18 carbon atoms in Engel) the unpopular hydrocarbon is why fats are hydrophobic. Unsaturated fatty acid- has one fewer hydrogen atom on each carbon of the double bond. Saturated Fatty acids- Fatty acids with no double bonds in their hydrocarbon chain that have the maximum number of hydrogen atoms. Corn Oil, Olive oil, vegetable oil. Trans Fats- When you see hydrogenated vegetable oil, unsaturated fats have been converted to saturated fats by adding hydrogen. Health risks, contribute to cardiovascular disease plaque, Omega-3 acids protect A monounsaturated fat has fatty acid with a single double bond in its carbon chain. A Polyunsaturated fat has a fatty acid with several double bonds. Phosphoric- major component of cell membranes. Contain only two fatty acids attached to glycerol instead of three. Hydrophilic phosphate on one end and hydrophobic fatty acids on the other trap water inside, the membrane. Steroids- are lipids with four fused carbon skeleton rings. Cholesterol- common in animal cell membranes, starting material for making steroids and sex hormones. Proteins-a polymer arrangement of 20 amino acids 20 amino monomers. Amino Acids- all have an amino group and a carbonyl group, which makes it acid. Peptide Bond- Cells Join amino acids together In a dehydration reaction that that links the carbonyl group of one amino acid to the amino group of the next amino acid as a water molecule is removed. Both depicted and disaccharide the monomers are Joined by dehydration reactions. Denomination- polypeptide chains unravel loosing their specific shape and function The function of each protein is a consequence of its specific shape, which is lost when protein denatures. A proteins shape depends on four levels of structure Primary Structure- is its unique sequence of amino acids Secondary- Coiling of a polypeptide into local patterns.. Cooling of the polypeptide chain in a secondary structure called an ALPHA HELIX, leads to a BETA PLEATED SHEATH. Tertiary- the overall three dimensional shape of a polypeptide, determines the function of a protein. Quaternary structure- two or more polypeptide chains one macromolecule. Collagen, a fibrous protein with three helical polypeptides intertwined into a larger ripple helix. Incorrectly folded proteins = alchemies and Parkinson. If a genetic mutation changes the primary structure of a protein, how might this destroy the protein functions? The amino acid sequence affects the secondary structure, which affects the tertiary, then the quarterly, Thus the primary structure determines the shape of a protein, its function depends on shape. A chaos could eliminate function. Nucleic Acids Gene- the amino acid sequence of a polypeptide is programmed by a discrete unit of reticence. DNA- Deoxyribonucleic acid, one of the two polymers called nucleic acid. One of the too polymers called Nucleic acid. Provided direction for its own replication, as a cell divides its genetic instructions are passed to each daughter cell. RNA- ribonucleic acid, illustrates the main roles of the SE two types of nucleic acids the production of proteins. A gene directs the synthesis of an RNA molecule. RNA cell. Translates nucleic acid language into protein language Nucleic acids are polymers of nucleotides Nucleotides- the monomers that make up nucleic acids. Each contain 3 parts, At the center a five carbon sugar, negatively charged phosphate group, nitrogenous base. Each DNA nucleotide has one of four nitrogenous bases, Adenine, Thymine, Cytosine, ND Guanine. RNA contains, GAG U racial instead of thymine. How to cite Bio book outline, Papers

gender roles Essay
gender roles Essay gender roles Essay Society places different values on being male and female, itââ¬â¢s these values that define us as individuals. Through a cross-cultural comparison I will be exploring the concept gender through a micro level within my family and then throughout the Maasai culture. The aspects of gender differ within concepts such as family life, roles and status, and power and authority. In the Maasai culture there a clearly prescribed social roles and status for the people. The Maasai people have many celebrated rituals that announce the change of the individual from one role to the other. (Donelly, etal, 2008) One of the most distinctive of this celebrations is the becoming of a Moran (warrior) itââ¬â¢s the transition from childhood to adulthood, within this ritual the initiate must under go circumcision and show his bravery by showing no pain during the process to prove he will be able to face the challenges he will be dealt with once becoming a Moran. Only men can become a Moran because it is seen as a mans role in society, and never a womanââ¬â¢s. The Moranââ¬â¢s obtain much honour by protecting their people against attack either groups or animals or any other type of harm to their people. It is the Moranââ¬â¢s role to take on any challenging tasks and their status is acknowledged and praise within the community by being given the best food. (Donelly, etal, 2008) Traditional Maasai family structure is based on polygamous marriage. There is a hierarchy within the family structure, the husband is head of the family and makes the decisions. The wife is responsible for running the household and has little to no say in the major decisions made. Because of the polygamous marriage lifestyle they live the Maasai men can marry as many women as they can afford to support. The Maasai women are also allowed to have different lovers. (Donelly, etal, 2008) Males are seen to have more power and authority over the women, the women understand that she does what her husband or another male tells her to do because if not she is seen as disrespecting him. The Maasai have to under go different rituals before being able to be married. For women this is the circumcision of the clitoris, it usually happens around

News and Journalism Essay Example | Topics and Well Written Essays - 2250 words
News and Journalism - Essay Example News and Journalism Amidst a whirlpool of contemporary movements like citizen journalism and new grassroots online media initiatives and with the mediascape changing at an incomprehensibly rapid pace, it's no wonder that so many publications are left wondering what the future looks like. Understanding the impact of these shifts and changes, and how an organization can take advantage of them to deliver a certain message and reach out to the audience, will be an important journey. It is not new to say that there is an ethnic bias in the mainstream media in almost all parts of the world and this fact has been proven beyond doubt by innumerable studies. Compounded by protracted ethno-political conflict, exacerbated by ineffective media reforms and coupled with the imperatives of market economics, the mainstream media in continues to perceive ethnicity as immutable and innate thereby neglecting its responsibility to demystify stereotypes and buttress institutions and practices that can ameliorate ethno-political conflict. It is natural for a media to keep its language readership in mind but impartiality and accuracy suffer as a result of this inherent bias. In an ethnically polarized society, ethnic bias in mainstream news media can take multiple forms and these are also reflected in the ownership of media houses. The problem facing journalists all over is how to protect their 'independence' when the world around them asks them to follow strategies and ethics which bind them to a certain ideology and path when no path or method is value neutral. And yet, the imperatives of journalism - accuracy, fairness, impartiality and reliability (Ross,2002) - bolstered by the freedom of expression, speech and information and open government provide the backbone of democratic pluralism. However, the multiplicity of voices in the media should not become a cacophony of half-truths, and must avoid the ills of rabid ethnocentrism and tabloid sensationalism. this could be done by promoting ethnic and gender balance in the newsrooms, regular updating and internal review of editing and style handbooks, in-house workshops and training on conflict sensitive journalism and greater co-operation between personnel and grass-roots level correspondents. Media reform has to have a holistic approach. Inextricably entwined with the impetus for media reform should also be the enabling framework of legislation regarding the right to information, the right to speech and the freedom of expression. A piecemeal approach to media reform, neglecting the wider canvas within which such reform takes place, is short-sighted and will not lead to any noticeable change. There are numerous external factors which influence the nature of the media. The rapid development of telecommunications and media technologies has transformed the very nature of the media by becoming an integral part of all events taking place in space and time. Live coverage in itself is recognized as a new event. Examples of this are the landing of US marines in Somalia and Haiti and the assault on the Beli dom and the Ostankino television station in Moscow. National and state politics have a powerful and crucial influence on the media in non-democratic regimes and unconsolidated democracies. In democratic societies

Ideologies as a Form of Oppression Essay Example | Topics and Well Written Essays - 1000 words
Ideologies as a Form of Oppression - Essay Example I am of the opinion that Bergerââ¬â¢s statement is one of Marxist elements. Advancing the idea of classes, and in a subtle way, brushing on class struggle and conflict caused by class segregation in society. Berger is presenting the labour world as one that has borrowed heavily from the feudal system that existed in medieval Europe. However, the emphasis on labour has fallen short of its purpose because of its focal point of comparison. This is because research on the symbolic meaning of this painting, reveals that it has many religious concepts. Most scholars are of the view that the paintingââ¬â¢s symbolism illustrates the conflict between secular and religious authorities. There is little mention of the conflict between the rich and the poor. Bergerââ¬â¢s statement is, therefore, subject to personal testimonies. Though he is a scholar of the art world himself, symbolism will always remain a personal reflection of ideas unless there is a presentation of undisputed evidence . One instance of evidence giving would involve giving another painting as a comparison to The Ambassadors. There are paintings that represent states of poverty in Europe like Spain 'Street-Boy of Seville' by Bartolome Esteban Murillo (1618-1682) or France 'Charity' by Adolph William Bouguereau (1825-1905). From the ideas expressed in the first paragraph of this paper, there appears to be a clear and direct link between events in history and those in present times. One can conclusively state that there is no present without a past. The occurrences of the present times are largely dependent on what happened in the past.

Critically evaluate the behaviours and traits for effective lead Essay
Critically evaluate the behaviours and traits for effective lead - Essay Example This process can be effective through appropriate management of change to adapt to all the environments of the business. Change management refers to an organized and planned approach that helps to address the various variations that occur in the business environments. This also involves the appropriate response mechanisms for responding to changes that may occur among the workplace because of the changes that the business adopts. Change management involves an outline of a process to follow in order to experience an overall transformation in the whole business together with its employees. This guideline represents different steps that an individual has to adhere to so that the organization and its employees are coordinated towards the process of fulfilling its objectives. Create a Sense of Urgency An organization can only change if it can acknowledge the change. The leaders of the organization and its employees must recognize the need for change. The leaders of the organization partic ularly the managers should strive to inform employees about the need for change in the organization. This is done by developing a sense of urgency in the organization and its employees about the outlined procedures to revolutionize the organization. The management should be able to convince the employees through instilling positive thinking amongst the employees. This can be done by explaining the future circumstances to employees and potential future threats that may necessitate a change. This is to prevent the company from falling into such pitfalls. The company can also examine opportunities that can be possible in the future, if the company adopts different mechanisms of approaching its business environment. The company can give forth-convincing explanations about the change it needs. This is a strong motivator to speech and thinking among employees in order to arrive at the necessary change. This will also attract support from other areas of interest such as customers and other industries that may have interests in the company. This further boosts confidence for the companyââ¬â¢s proposal since all parties are able to accept the change (Green, 2007, 167). Form a Powerful Coalition The organization should focus on leading the change to realize change. The company organization needs to bring a group of experienced individuals that are able to further the objectives of the organization towards change. Individuals from different levels of the companyââ¬â¢s hierarchy, who draw their power from different sources, should be pooled together because they can offer the necessary advice on how change can be realized. This coalition will offer a priceless effort towards furthering the companyââ¬â¢s urgency by build the required momentum towards change (Cameron & Green, 2009, 121). Create a Vision for Change The organization should be able to consolidate its ideas of change and bring it to the individualââ¬â¢s level of understanding. The vision for change should summarize the core values that the organization aims to achieve and should be effectively comprehended by the coalition formed to push for it (Vukotich, 2011, 41). Communicate the Vision The organization should ensure that its vision is thoroughly communicated and embedded in the organization. This is done through frequent expression of this vision in the decisions that the company makes,
