Explain the four factors of production. In what way are they related to the circular flow diagram? Explain the four factors of production. In what way are they related to the circular flow diagram? Solution The four factors of production are land, labor, capital and entrepreneurship. These factors are used in almost every firm to produce a commodity. The returns to these factors are rent, wages, interest and profits respectively. The land, capital, labor and entrepreneurial services are the factor inputs by the households to a firm. The households in turn gets rent, interest, wages and profits respectively from the firm..

Is this a Cohort Study? What would be an example of a Cohort study? 1) Solution Cohort studies, case control studies and randomized controlled trials When people read about a research study, they may not pay attention to how the study was designed. But to understand the quality of the findings, it\'s important to know a bit about study design. According to the widely-accepted hierarchy of evidence, the most reliable evidence comes from systematic reviews (see Infocus, Summer 2004), followed by evidence from randomized controlled clinical trials, cohort studies and then case control studies. Research studies typically fall into one of two main categories: Observational studies Here researchers observe the effect of a risk factor, diagnostic test or treatment without trying to influence what happens. Such studies are usually \"retrospective\".

Discuss the involvement of interest groups in the political circumstances that affect \"agenda setting.\" You should incorporate the specific ways they influence agenda setting in your response. Solution Agenda setting is the ability to influence the importance of topics on public agenda. The involvement of interest groups in the political circumstances that affect \"agenda setting\", gives more depth and gravity to the process. It makes the process more relevant and germane. Most importnatly, it gives the matter a practical feel and a tangible feel. The agenda becomes identifiable due to the involvement of interest groups. For example people in India are demanding one rank one pension (OROP) for army and defense personnels, on the same lines as civic officials. The involvement of retired defense personnel (interest groups) has given the process a more relevant outlook. More political parties are involved now. The ways in which the agenda setting can be done are: first level agenda setting - here the importnace is given to the issue on hand. The next level or the second level of agenda setting gives importance to the attributes of the agenda. This level considers how opinion are affected by the agenda..

Determine which of these statements describing the cytochrome P450 family of enzymes or the mechanism of action are true. a) The iron in cytochrome P450s can exist in both Fe2 and Fe3 states in a single catalytic cycle. b) The coenzyme NADPH can serve as a source of electrons for cytochrome P450s. c) Fe3 acts as a general base during the catalytic cycle. d) Each cytochrome P450 isoform can act on only one specific organic substrate. e) Cytochrome P450 uses molecular oxygen (O2) as a reactant. f) The activity of cytochrome P450 generally results in carboxylated products. Please include an explanation with your answer! Thank you. Solution Cytochrome P450 is a class of enzymes essential for many metabolic reactions. This includes about 50 enzymes. ‘Heme’ is the cofactor of all these enzymes, means ‘heme’ is present in the active site of the enzyme. ‘Heme’ shifts from Ferrous and ferric states as electrons are accepted and donated. So, statement (a) is totally correct. And this iron component is present in the centre of porphyrin ring. So, single/same catalytic site is there for ferrous and ferric. In mitochondria, electrons are transferred from NADPH by cytochrome P450 reductase. So, statement (b) is correct. Base is anything which accepts protons. Fe3 (ferric) accepts protons from oxygen in mitochondria. So, statement (c) is also correct. Statement (d) is incorrect. There are several isoforms of P450. Among these CYP3A4 is the most important. It metabolizes nearly half of the total drugs used in clinical biology nowadays. These include codeine, acetaminophen, erythromycin etc. So, one isoform would act on many organic substrates. Statement (e) is correct. Yes, it uses molecular oxygen, and converts it to water. Statement (f) is incorrect. Activity of cytochrome P450 resulted in formation of water (by reduction of oxygen); this is not a carboxylated product..

Describe some of the different ways members of Congress can represent the American people. What are the principles behind sociological and agency representation? What are some examples of each type? Describe the difference between a trustee and a delegate. Which type of representation do you believe is the best? Describe the electoral connection in Congress. Describe some examples of constituency service. What are some of the ways a member of Congress can directly aid their state or district? What effect do incumbency and redistricting have in the makeup of Congress? Solution Congress is the most important representative institution in american government. It is the voice of the american people. Members of congress consider different views and demands as they reprsents their district. Member of congress regularly reach out to their constituents and devote a great amount of staff amount to constituency service . teh farmers of the constitution provided for bicameral legislature with House and Senate to serve different constituencies . They are Law and Policy makers and on the other hand represent the needs and the best interest of their particular constituents. The Snete is choosen by the state legislatures and serve a total six year term represents the elite member of society . While the house who are elected by voters in congressional districts serves a two year term represent the people or well organized local interests. Sociological representation is a type of representation in which representative have similar racial , ethnic , religious or educational background as their constituents . Sociological likeness helps promote good represntation by the government . On the other hand agency representation act as an agent of his or her constituency. Constituent hire their agency representative and if the constituent feel they are not being represnted well they can fire their representative . There are two different ways elected legistators in congress can act. One way is to act as a trustee . this mean that the legistators will vote and act according to their own personal belief and what they feel is best for society Unlike the trustee a delegate vote according to whom they represents . The deligate connects to their constituents completely tries hard to epathize with their feelings and wants to be liked by the constituents ..

You cut your finger, and your skin cells divide to heal up the wound. What type of nuclear division is happening in the skin cells? (Mitosis or meiosis?) and why. You cut your finger, and your skin cells divide to heal up the wound. What type of nuclear division is happening in the skin cells? (Mitosis or meiosis?) and why. Solution When we cut our finger the skin cells undergo mitotic division to heal up the wound, because skin is a somatic cell not a germ cell. Only germ cells like egg cell and sperm cells undergo meiosis as these cells are the only haploid and give rise to a new organism with n+n = 2n number of chromosomes. In our body rest all cells divide by mitosis, as mitosis ensures that (2n)chromosomes after dividing are distributed evenly between two cells and maintain the idenity of the cell while dividing..

Question 29 Answer : an adult Long bones have three unmistakable areas the diaphysis, or shaft; the metaphysis, or the flared end of the pole; and the epiphysis, or end top of the bone. Long bone development happens at the epiphyseal or development plate, situated between the metaphysis and epiphysis.The development plate itself is comprised of a framework of ligament. Osteoblasts, the fibroblast-like cells in charge of bone creation, are set down on this platform. The osteoblasts create a collagen network that is then mineralized to wind up distinctly new bone. On the off chance that development is as yet progressing, more ligament is set down on that bone as the development plate moves more distant far from the focal point of the pole, and the procedure rehashes. At the point when development is at last achieved, development stops and the epiphysis and metaphysispermanently fuse together =================== Question 30 Answer : the remains o traces of an accent organism including fossilized bones, casts an dmummies a. the Snagglus Rex fossil you found must be a male. b. nothing -- information on Snagglus Rex in the same region does not give you any information at all about the Snagglus.

Which of the following is an amino acid side chains can receives a terminal phosphate from an ATP molecule? Serine Threonine Tyrosine None of the above All of the aboveA. SerineB. ThreonineC. TyrosineD. None of the aboveE. All of the above Solution Answer: E. All of the above Explanation: While phosphorylation is a prevalent post-translational modification (PTM) for regulating protein function, it only occurs at the side chains of three amino acids, serine, threonine and tyrosine, in eukaryotic cells. These amino acids have a nucleophilic (–OH) group that attacks the terminal phosphate group (-PO32-) on the universal phosphoryl donor adenosine triphosphate (ATP), resulting in the transfer of the phosphate group to the amino acid side chain..

When animals die, muscles stiffen in rigor mortis because 1. actin and myosin cannot bind without ATP. 2. actin and myosin cannot separate without ATP. 3. ATP forms cross-bridges between filaments. Solution Answer : The correct answer is 2 (actin and myosin cannot separate without ATP).Explanation : After the death, ATP synthesis stops as breathing stops. However, so the crossbridges cannot detach from actin. The resulting condition, in which muscles are in a state of rigidity( cannot contract or stretch) is called rigor mortis..

What isThe difference between multiple independent variables and multiple levels of independent variables are that multiple independent variables Solution The independent variables can be of different types, and these different types can be present in the same study. Qualitative independent variables describe different kinds of treatments. Independent variables cannot be manipulated by the researcher. If more than one independent variable is examined, the independent variables may interact in such a way that the effect of one or more variables depends upon the levels of one or more dependent variables.

1) A person who is shot in the head and the bullet goes through the cerebral cortex in the parietal lobe makes a lesion that results in: a. Twitching of the arms b. Difficulty recognizing faces c. The inability to speak d. An inability to mail a letter e. Amnesia Solution Damage to the parietal lobe of cerebral cortex; Answer is \'C\': The inability to speak. In mammalian brain, the parietal lobe is one of the four major lobes of the cerebral cortex. It is positioned above the occipital lobe and behind the frontal lobe. The parietal lobe mainly integrates sensory information including spatial sense, navigation; the sense of touch in the somatosensory cortex and the dorsal stream of the visual system. The major sensory inputs from the skin such as touch, temperature, and pain receptors, relay through the thalamus to the parietal lobe. Several areas of parietal lobe are involved in language processing. Damage to the parietal lobe may result in \"Gerstmann\'s Syndrome.\" including right-left confusion, difficulty with writing, calulations and produce disorders of language (aphasia) and the inability to perceive objects normally. Answer \'d\'is also correct to some extent: An inability to mail a letter. Damage to the parietal lobe result inability to focus visual attention. A person can’t produce words from memory for writing and faces problems in reading because inability to recognise the word. However frontal lobe of cerebral cortex also plays a major role in flexible thinking process and memory. b. Difficulty recognizing faces: Related to temporal lobe of brain e. Amnesia: Associated with damage to the hippocampus and related areas..

What is the purpose of an approval committee in the software development process? Who is usually in this committee? Solution Approval committee usually serves as the decisions make body concerning investments in software development process projects. Committee usually has a wide managerial representation plus therefore can avoid allocate capital that will provide just narrow managerial benefit. The approval committee usually has project mistake responsibilities as fine; monitor project presentation later than the project have been established. The work of the approval committee will differ from association to association, but usually consists of high-level manager since right through the association. In IT the work of a steering committee is to create positive each IT project ropes business goal and objectives. The steering committee is frequently in charge for creating running group and chooses the correct expert to finish a project. Planned changes to a project\'s range projects should be accepted by the steering committee to make sure the change side with the project aim. a lot of steering committee make project charter to grip project team accountable..

(a) List two DNA viruses and two RNA viruses. (b) What is a Lytic cycle? (c) What must happen for a virus to attach to a cell? (d) Why wouldn\'t a virus infect just any type of cell? Solution 1. I: dsDNA viruses (e.g. Adenoviruses, Herpesviruses, Poxviruses) II: ssDNA viruses (+ strand or \"sense\") DNA (e.g. Parvoviruses) III: dsRNA viruses (e.g. Reoviruses) IV: (+)ssRNA viruses (+ strand or sense) RNA (e.g. Picornaviruses, Togaviruses) 2. A temperate bacteriophage has lytic and lysogenic cycles. In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is integrated into the host genome, in which it is passed on to next generations. 3. When virus attached to a cell, it delivers its DNA or RNA into the host cell. Therefore, contamination requires that the virus get through the cell membrane. Some viruses remain outside the cell. They connect to the membrane at specific receptor. Once connected the virus injects its DNA or RNA into the cell. Enveloped viruses are enclosed in a membrane just like that of the host cell. The virus and the envelope fuse and the virus enters the cell through endocytosis. In the first example simple genetic material enters the cell. In the second case the entire virus from the envelope enters the cell. 4. All viruses have a form of protein at the outer coat or envelope that \"feels\" or \"acknowledges\" the right host cell.This protein attaches the virus to the membrane of the host cell.Some enveloped viruses can dissolve proper through the cell membrane of the host because each the virus envelope and the cell membrane are product of lipids. Those viruses that don\'t enter the cell have to inject their contents (genetic commands, enzymes) into the host cell. Those viruses that dissolve into a cellular certainly release their contents as soon as in the host. In either case, the consequences are the identical.So virus would not infect each cell. Hope everything is clear and you like the answer..

What are the differences between the solidification of pure metals and metal alloys? Solution During solidification, pure metal converts from liquid state to solid sate at a single temperature while an alloy solidifies over a range of temperature. Pure metal composition remains constant throughout solidification process but the composition of alloy changes continuously. But the composition of alloy in the solid sate becomes same as that when it was in liquid state.that is, this change of composition take place only during liquid+ solid state. Importantly , all this occurs only during cooling under equilibrium conditions..
