The photos should depict any physical injury that may be on the body of the victim. Physical medical examination on the body is then carried out. This includes the collection of hair and fiber that may be on the body. Fingernail scrapings and dental floss should be collected. This is done by the use of wooden sticks. The collection of urine and sweat samples on the victim is also done. The medical officer should retrieve any traces of fluid on the victim’s body. Internal fluids are then collected. The collection should be mainly done on the mouth, vaginal or anal cavity (Schiro, 2015). The labeling of each fluid should be accurate. In the instance where the incidence has occurred in the bedroom, any piece bedding should be collected. Spreaders, bed sheets and comforters should be analyzed for any fluid traces. They are then air dried and packaged differently. To ensure that the no traces of evidence are lost during collection and packaging, the collector should use the side lighting technique (Schiro,

case summary of benefits of team work :: essays research papers

Benefits of teamwork: 1.http://nadabs.tripod.com/team/html Author: Nada AbiSamra. Teams outperform individuals because teams generate a special energy. This energy develops as team members work together fusing their personal energies and talents to deliver tangible performance results. There are number of benefits for team work. Among them are: a)  Ã‚  Ã‚  Ã‚  Ã‚  Distributing the workload b)  Ã‚  Ã‚  Ã‚  Ã‚  Reinforcing individual capabilities c)  Ã‚  Ã‚  Ã‚  Ã‚  Creating participation and involvement d)  Ã‚  Ã‚  Ã‚  Ã‚  Making better decisions e)  Ã‚  Ã‚  Ã‚  Ã‚  Feeling like we play a part in the work being done. f)  Ã‚  Ã‚  Ã‚  Ã‚  Generating a diversity of ideas, etc. 2.  Ã‚  Ã‚  Ã‚  Ã‚   Publisher: HRZone.com Author: Sue Campbell Work teams are essential to organization success. The following benefits are described briefly. a)  Ã‚  Ã‚  Ã‚  Ã‚  Job satisfaction: People who prefer group work are more satisfied with group work. b)  Ã‚  Ã‚  Ã‚  Ã‚  Higher work group productivity: People working in groups are more productive when tasks require working together and when rewards are related to group success. Groups that had both integrated work and members on their team who had a high preference for group work had high productivity even when rewards were not group based. c)  Ã‚  Ã‚  Ã‚  Ã‚  Brains and ability – higher GPAs Jason D.

A Cycle Is a Biological Pathway or Process in Which the End Product

A cycle is a biological pathway or process in which the end product of one cycle becomes the starting point for the next cycles Write an essay about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration, the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration, the production of lactate during which the muscles have a limited supply of oxygen, and however keep working despite this.Aerobic respiration requires oxygen and glucose present to work, and occurs in 4 stages: 1) Glycolysis- the splitting of a 6-carbon glucose molecule into 2 3-carbon pyruvate molecules. There is a net gain of 2 ATP’s produced. 2) Link reaction- the conversion of the 3-carbon pyruvate molecule into carbon dioxide and a 2-carbon acetyl co-enzyme A molecule. No ATP is produced during this stage. 3) Krebs cycle- the introduction of acetyl co-enzyme A into a cycle of oxidation-reduction reactions that yield some ATP and a large number of electrons. ) Electron transport chain (ETC) – electrons used from Krebs cycle to synthesise ATP with water produced as a by-product. Glycolysis is the initial stage of aerobic respiration, and it takes place in the cytoplasm of cell. It is the breakdown of glucose into pyruvate, (which then goes in to initiate the second stage, the link reaction, and so forth) although there are a number of smaller enzyme controlled reactions for tis to take place. 1. Activation of glucose by phosphorylation.Before glucose can be split into 2 pyruvate molecules, it first must be made more reactive by the addition of 2 phosphate molecules, donated by the hydrolysis of 2 ATP molecules to ADP. This provides the energy to activate glucose. 2. Splitting of the phosphorylated glucose. Each glucose is split into 2 3-carbon molecules of triose phosphate . 3. Oxidation of triose phosphate. Triose phosphate is oxidized transferring 2 hydrogen molecules to a hydrogen-carrier, NAD to produce reduced NADH. 4. Production of ATP. Enzyme-controlled reactions convert each triose phosphate into 3-carbon pyruvate. molecules of ATP are regenerated from ADP. The pyruvate molecules produced in the cytoplasm during glycolysis are actively transported into the matrix of the mitochondria where the link reaction takes place. Pyruvate undergoes a series of reactions to be made into acetyl co-enzyme A. the following changes occur. * Pyruvate is oxidised by the removal of hydrogen. This hydrogen then binds to NAD to produce reduced NADH (which is later used to produce ATP late). * The 2-carbon molecule acetyl group that is thereby formed combines with a coenzyme, coenzyme A (CoA) to produce Acetyl CoA. A carbon dioxide molecule is formed from each pyruvate. Pyruvate + NAD + CoA acetyl CoA + reduced NADH + CO2 The Krebs cycle involves a series of oxidat ion-reduction reactions that take place in the matrix of mitochondria. * the 2-carbon acetyl CoA from the link reaction with a 4-carbon molecule to produce a 6-carbon molecule. * This 6-carbon molecule loses carbon dioxide and hydrogen’s to give a 4-carbon molecule and a single molecule of ATP produced as a result of substrate-level phosphorylation. The 4-carbon molecule can now combine with a new molecule of acetyl CoA to begin the cycle again. The ETC takes place in the cristae of the mitochondria, where ATP is synthesised using the ETC as followed; * The H+ atoms produced during glycolysis and the Krebs cycle combine with the NAD and FAD that are attached to the cristae. * The reduced NAD and FAD donate the e- of the hydrogen atoms they are carrying to the first molecule in the ETC * This releases the protons from the hydrogen atoms and these protons are actively transported across the inner mitochondrion membrane. The e- meanwhile, pass along the ETC molecules in a series of oxidation-reduction reactions. The e- lose energy as the pass down the chain, some of this is used to combine ADP and inorganic phosphate to produce ATP. The remaining energy is used to from heat. * The protons accumulate in the space between the 2 mitochondrion membranes before they diffuse back into the mitochondrion matrix via protein channels. * At the end of the chain the e- combine with the protons and oxygen to form water.Oxygen is therefore the final acceptor in the ETC. Photosynthesis Photosynthesis occurs in 2 stages. The light-dependent reaction which takes place in the thylakoid, and the light-independent which takes place in the stroma. Both are vital for the production of ATP. The light-dependent needs light to undergo its reactions. The thylakoid contains chlorophyll which absorbs light. Photophosphorylation occurs during this reaction which is the making of ADP plus an inorganic phosphate to make ATP.NADP is also reduced during this reaction into NADPH. As well a s this happening in the light-dependent reaction, water is split via photolysis in to protons and electrons and oxygen which diffuses out of the leaf. The light-independent reactions does not require light to process, however it does rely on 2 major products of the light-dependent reaction to take place, ATP and NADPH. This reaction is shown in the form of the Calvin cycle. * CO2 enters the stroma from the light-dependent reaction, and produces 2 3-carbon glycerate-3-phosphate. 2 ATP molecules then donate 2 phosphate molecules to produce ADP. And NADPH is oxidized to produce NADP. This goes on to form 2 3-carbon triose phosphate molecules. * 1-carbon from the triose phosphate molecule is then stored to contribute to making glucose. ATP is then reduced again donating a phosphate molecule to produce 5-carbon rubiscose bisphosphate, this in turn then produces and enzyme rubisco which catalyses the whole cycle again. * This cycle must happen 6 times in order to make 1 glucose molecule.

Charles Darwin And Darwin s Theories On The Human...

When Charles Darwin published The Origen of Species in 1859, he knew the asseverations made in it would cause a rift in the scientific community of his day. Also, he knew that his work would not be received by humanity with open arms because of the dogmatic idea of creation that was predominant in his time. Nonetheless, he went ahead and published the results of his extensive and detailed work because he knew, that not doing so would cause him to lose the right to claim this discovery for himself. At first, the scientific community attacked his arguments because they were against the traditional beliefs, but eventually his ideas began to gain ground until they became one of the pillars of modern science. Upon considering these facts, I believe it is important to ponder on the reasons behind the opposition to Darwin’s ideas, how he managed to convey them, and more importantly how these ideas helped shape our understanding of biological history. Before even talking about The Ori gen of Species or Darwin’s theories it is important to discuss the historical context in which this book was first published. Up to this point in history, the origin of all life on the planet had been explained using a theological approach. In other words, God had created the world along with all its vegetation, then created all the animals, and then created humans as the center of creation. According to this view, all animals, trees, and landscapes we see today are the same that existed when Adam andShow MoreRelatedDarwin s Theory Of Evolution1115 Words   |  5 Pages There are many theories as to what scientist believe is the forth coming of evolution or what they deem to be the reasoning behind its development. However, Charles Darwin would change the theories of evolution and would go down in history as one of the greatest influential figures in human existence.

Charles Darwin put forth a coherent theory of evolution and amassed a great body of evidence in support of this theory.
