How would a forensic anthropologist that does anthropometry deal with the accusation that they are practicing pseudoscience? Solution Anthropometry signifies the measurement of human individual. It is tool of anthropology. Science has no absolute truth. It begins from an observation and may contribute to a greater story. These observations may be changed or removed by other observations wjich implies that the greater story is not fixed but changing. Alphonso Bertillon started anthropometry who believed that people could be identified by measurement of specific body parts. Human skull measurement was thought to indicate brain size and thus, intelligence. It was proven that white people had bigger skull which signifies more intelligence while black people had smaller skulls thus lesser intelligence. The societal acceptance of science has now become problematic in this case. The pseudoscienctific utilisation of anthropometry as an evidence for racial hierarchy helped influence the racial discrimination. In the early19th and 20th century anthropometry was regarded as a pseudoscience which was mainly used to classify potential criminals from facial characteristics..

Describe how a selectively permeable membrane is involved in osmosis. Include the role that the solute concentration plays in the direction of water movement. Now think about how this process may differ between plant and animal cells. For instance, how might cell walls disrupt the role of solute concentration and cause one to refute a hypothesis for the direction of water movement based on water concentration alone? Solution Let me first briefly descibe you how does osmosis happen. Consider there are two compartments contaning a particular solute in a solvent seperated by a semi permeable membrane. If there exists a solute difference between the two compartments, then solvent moves from the region of lower conceration (with respect to solute) to higher concentration (with respect to solute) until it reaches equilibrium. That means semi permeable membrane is permeable to solvent. Now comes the situation of in vivo (i.e., within the body). The cells, whether from animals or plants are usually hypertonic in nature that means cells have higher ionic concentration compared to its external environment (water is the solvent). Then how do these cells maintain such a higher ionic concentration by refuting the process of osmosis/diffusion. First let us consider the plant cell. Plant cell has two coverages, namely plasma membrane and cell wall. Cell wall in plant cell is made up of cellulose and cellulose is a polysacharide provides the rigidity to the cells. Actually, it is the plasma membrane which does not allow the movement of water molecules to cross based on gradient of solutes. Let me talk about the cell wall at the end of this answer. What makes that plasma membrane to refute the law of osmosis ? It is its structural organization. Plasma membrane is made up of phospholipids, cholesterol and proteins mainly. Phospholipids are oriented in bilayer form facing its hydrophilic (water loving) head at both the ends interacing with cytoplasma and extracellular environment and its hydrophobic (water hating) tails are oriented deep within the membrane interacing each other. Plasma membrane of either plant or animal are highly impermeable to the solutes and water. Permeability of plasma membrane highly depends on the nature of solutes. If solute is smaller in size and hydrophobic in nature it diffuses through the membrane quiet easily but it is difficult for the hydrophilic and largge size solutes. Charge of the solutes also plays the major role. It is not only based on the concentration gradient but also based on charge gradient. Hence it is known as electrochemical gradient. It is actually a beautiful mechanism of cells to produce energy required for the cell based on electrochemical gradient (within mitochondria) And for water, it is difficult to pass through. There is a term called \"Activation energy\". Energy need to be supplied in order to facilitate the movement of solutes.Lower the activation energy, lesser the energy required and vica versa. Comi.

Compare and contrast Erikson\'s fifth stage of personality development and Marcia\'s theory on identity statuses. Which do you agree with and why? Solution Yes , i agree , as the Marcia\'s theory on identity statuses are developed based on Erikson\'s fifth stage of personality development. The fifth phase of Erikson\'s life stage hypothesis is identity and role confusion.. Strains for a juvenile can know him/herself, what s/he will do with his/her life, fitting in gathering sand encountering things. Knowing him/herself is imperative to a pre-adult in light of the fact that on the off chance that he or she knows him/herself, his/her capacities, he or she can shape his/her life as indicated by the properties and capacities that s/he has. Young people take a stab at encountering things, for example, fitting into social gatherings, encountering things to think about themselves and capability of their identity regardless of the possibility that they need to go out on a limb. Accordingly to these strains, these encounters may bring about change in conduct, identity and look of a youthful. What\'s more, these encounters keep on happening until the pre- adult get over this identity and role confusion. In light of Erik Erikson\'s noteworthy work on character and psychosocial improvement in the 1960s, Canadian formative clinician James Marcia refined and amplified Erikson\'s model, principally concentrating on youthful development. Tending to Erikson\'s thought of character emergency, Marcia set that the immature stage comprises neither of personality determination nor personality disarray, but instead how much one has investigated and focused on a personality in an assortment of life areas from employment, religion, social decisions, sex parts, et cetera. Marcia\'s hypothesis of character accomplishment contends that two unmistakable parts frame a juvenile\'s personality: emergency (i. e. a period when one\'s qualities and decisions are being reexamined) and duty. He characterized a crisis as a period of change where old qualities or decisions are being reevaluated. The end result of an crisis prompts to a guarantee made to a specific part or esteem.. Upon developing a semi-structured interview for identity research, Marcia proposed Identity Statuses of psychological identity development: · Identity Diffusion –: the status in which the adolescent does no have a feeling of having options; he or she has not yet made (nor is endeavoring/willing to make) a promise Identity Foreclosure : the status in which the immature appears to focus on some significant parts, qualities, or objectives for what\'s to come. Teenagers in this stage have not encountered a personality emergency. They have a tendency to fit in with the desires of others in regards to their future (e. g. permitting a parent to decide a profession course) As such, these people have not investigated a scope of alternatives. Identity Moratorium – the status in which the juvenile is as of now in a.

Briefly describe the phenomenon of exon shuffling and provide an example of this in living systems Solution exon shuffling is a molecular mechanism for the formation of new genes. in this process 2 or more exons are from different genes are brought together at a non-homologous site or there is a duplication in the exons forming new intron-exon structures. exon shuffling takes place by various processes such as transposon-mediated, cross over between gametes during sexual recombination or any inappropriate recombinations. living examples for exon shuffling are metazoans such as Homo sapiens have post- transcriptional exon shuffling, Drosophila with 39% of gene rearrangements. during evolution, 1-1 shuffling units were found in Trichoplax adhaerans and Nematostella vectensis..

Use the D.A.R.E. critical thinking components to discuss article: Define, Analyze, Resolve, and Evaluate. Define: What is article about? (do not discuss the important points here) Analyze: a. Discuss salient/important ideas or points. b. What impact do you think this news has or will have on you or the world we live in? Resolve: Generate a few questions that you have about the information. Evaluate: Is it a controversial or a critical issue that needs more research? Is it information you think should be more widely publicized? Should any action be taken? by whom? Explain your thoughts. Solution Biological Science in the News News presents in form of sound, picture, text individually or in combinations. Various studies reveal that sound, picture or text has significant effects on human’s body and behavior. On the basis of that, the article has greater potential to discuss the effects of news through biological aspects. The representation and information of news makes human feel better or worse accordingly. That feelings and impressions effect the brain of human body significantly which can measure by the level of hormones like dopamine, serotonine, noradrenaline and others. These impacts may bring society to feel accountable or no accountable to the particular effects of news. People live in society and news comes from their interactions. Therefore, it would have greater impacts to the physiological and behavioral factors of human. Now, scientist, activists, and researchers are pointing out the possible harmful effects of news. Many news channels are serving news on dinning plates. They are making the news exclusive and hot. Therefore, it requires taking a stop on such news and making effective preventions..

An organization called the Repository for Germinal choice in Escondido, CA once served as a sperm bank for Nobel Prize winners and others possessing high IQs. Dozens of babies have now been produced by artificial insemination from the sperm bank. Do you regard this as wise or unwise, ethic or unethical, foolish or inspired? Solution The major rising ethical challenge is the connection between the pre-selection of embryos for \"babies with high IQ (intelligent quoscent) based on meticulous genetic analysis of sperm donation & artificial insemination followed by rising discrimination of \"disabled people\". Therefore, even though, it is a \"wise methodology\" but highly \"unethical\" and foolish due to chances of occurrence of genetic abnormalities. This ethical problem is associated with selection of future children based on their low levels of disabilities and abnormalities. The genetic abnormalities of prenatal baby with any other serious diseases but this method of screening is leading to reinforcement of disable people discrimination and stigmatization. There is chance of unintended multiple pregnancy & success rate is lesser. The meticulous ethical factor associated with donated sperm (for high IQ) via artificial insemination is any presence of sexually transmitted diseases (HIV etc), genetic disease carriers (sickle cell anemia). This methodology is regarded as “wise protocol” to those women who are unable to participate in sexual intercourse followed by sperm implantation into the women fallopian tube for fertilization with egg..

Solution Public goods is a good which is non excludable and non rivalrous. Where use by one individual doesnot effect the availabilty by others Common goods are rival but not excludable Example of public goods are national defense, uncongested nontoll roada Example of common resource are fish in the ocean, environment etc Market doesnot effect the public good because the person using it is a free rider. He will think that others will pay for his good. There can be a market interuption in common resources as private player can come in and develop a market for products like pure air and water..

What does IPO underpricing refer to? When in recent decades has it been most severe? What are some reasons that underwriters might want to underprice their IPOs? On the other hand, what might be some problems with this approach? Solution IPO refers to Initial Public Offer and underpricing refers to Pricing of shares lower than the market value. Hence, IPO Underpricing refers to the listing of the initial issue of the company at the rate below the market value of the share. Underwriters does so to make the shares feasible for every investor to invest in. Not every share is approachable to the small investors. So the motive of the IPO Underpricing is to make the issue approachable financially to small and big investors both.Thereby, knocking the opportunities for potential small investors and grabing small pockets of many investors. The problem can definitely be that the big investors doesnot look these IPO\'s and show less interest in investing them and hence the issuer will not be able to collect fund in one go..

What role does ethics play in leadership? Do you believe that some people abuse it? Why or why not? Provide examples. Solution his is extremely interesting territory. Organisations and people within organisations rarely if ever demonstrate a homogeneous mix of ethical values, but they do have to function. Ask the question. How will the Iraq even create a temporary framework to govern given that it seeks to balance such disparate issues? History tells us that we compromise because the alternatives are often far worse. Pragmatism becomes the order of the day and I think that this is a pattern that is repeated in corporations. Organisations function according to their perception of how they need to respond to the power of the circumstances around them. There is a behavioural bottom line for organisations which should not be crossed (ethical considerations embodied in the law) but, there is a vast array of other ethical issues that may or may not be taken on board. They are generally only taken on board when it is perceived that the short term self interest of the company matches the ethical value. Organisations then present different images to their stakeholders to maximise the warm glow that they project. Profit to the shareholders. Respect me vibes to the institutions. We work for our workforce vibes to employees and their supporters. All these images conflict and one of the key roles of leadership (setting the agenda) is to ensure that this conflict is managed and the business machine does not slow down. Those leaders who have gone through the processes of: 1. Learning to lead and manage themselves. 2. Developing a clear understanding their values and goals. 3. Learning to lead and motivate others. 4. Learning how to apply leadership strategically. will manage without falling off the horse. It is unlikely however, that they will lead on ethics even if their standpoint is ahead of their company\'s minimal position. They are more likely to gratefully respond to what the social consensus seeks to make imperative..
