Why should anyone else care about what I do with my sewage on my own property? Integrate specific examples from course material in your response. Solution Anyone is going to care what you are going to do with house hold sewage generation and disposal of sewage into the environment because sewage may causes high environmental problem - climate change due to presence more non-degradable phosphorous & organic compounds. Human impacts on environmental change via sewage are leading to the following imbalance in the ecosystem at trophic levels. Household-sewage and toxic lead pollutants are other factors responsible for death of the photosynthetic microalgae & macroalgae result in dead zone with photosynthetic biomass. This dead zone formation is mainly have higher impact on nitrogen cycle level of water and nitrogen cycle is going to increase due to higher farm fertilizers mixing into the aquatic zone via storm water finally bacterial activity is going to reduce “dissolved oxygen level” available to the other aquatic species dramatically via aerobic respiration.

Why do viral particles, zymosan on fungi, endotoxin (LPS) from gram negative bacteria, bacterial DNA, and bacterial flagellin each induce the same proinflammatory response, and especially the production of IL-8, IL-12, IL-1, IL-6, and TNF-alpha? What is the link between this and c-reactive protein levels in the blood stream? Solution The immune system is comprised of two branches: innate and acquired immunity. The innate immune system is the first line of host defense against pathogens and is mediated by phagocytes including macrophages and dendritic cells (DCs). The innate immune response relies on recognition of evolutionarily conserved structures on pathogens, termed pathogen-associated molecular patterns (PAMPs), through a limited number of germ line-encoded pattern recognition receptors (PRRs), Upon PAMP recognition, PRRs present at the cell surface or intracellularly signal to the host the presence of infection and trigger proinflammatory and antimicrobial responses by activating a multitude of intracellular signaling pathways, including adaptor molecules, kinases, and transcription factors. Several classes of PRRs, including Toll-like receptors triggers functional maturation of dendritic cells and leads to initiation of antigen-specific adaptive immune responses. Macrophages activated at sites of tissue injury produce a number of cytokines into the bloodstream, most notable of which are the interleukins IL-1, IL-6 and IL-8, and TNF-, which induces hepatocytes to synthesize acute phase proteins (APP) including C- reactive protein. The level of CRP in blood plasma can rise as high as 1000-fold with inflammation. Thus the greatly raised level of c- reactive protein in the blood stream can be viewed as a strategy to overcome the poplulation of pathogens..

Which of following is not a class of the phylum platyhelminthes? Trematoda Turbellaria Nemertea Monogenea. Cestoda Which one of the following statements regarding the origin of metazoans has the most support? Ancient metazoans, similar to members of the phylum Placozoa, have been ruled out as ancestral metazoans. The choanoflagellates share features with the sponges, like having collars of surrounding a flagellum and being colonial. These shared features suggest a link to at least metazoan lineage. Metazoans are derived from many separate of unicellular organisms. Modern sponges have a genetic makeup that reflects their ancestral status. The traditional view of cnidarians relative to germ layers is that cnidaria possess two germ layers, ectoderm and endoderm. only one germ layer, the ectoderm, that differentiates into the two tissue layers. two germ layers, ectoderm and mesoderm. definitely all three germ layers including the mesoglea as it is derived from ectoderm. two germ layers, endoderm and mesoderm.

What are two ways that meiosis could produce gametes that contain genetic material that is different from the parent cell? What are two ways that meiosis could produce gametes that contain genetic material that is different from the parent cell? What are two ways that meiosis could produce gametes that contain genetic material that is different from the parent cell? Solution Answer: The two ways that meiosis could produce gametes which differ genetically from its parent cells are as under: (1) During meiosis, homologous chromosomes undergo independent assortment. This means that the chromosomes associate in no way with one another. Thus, the gametes so formed may have any combination of paternal and maternal chromosomes. (2) Crossing over results in the exchange of genetic material between homologous chromosomes, resulting in recombinant chromosomes. It occurs during the pachytene stage of meiosis I. This process gives rise to new recombinant varieties and thus the gamete so produced differ genetically from the parentals..

what is the process in society that made this change to advertising objective throughout history? what objective in the list of advertising objectives bears a qualitative change in it or represents a new level of diff Solution Over the years, the advertising objectives has changed with change in societal structure and its morality. Advertising is a process to attract customer towards a product or service and it takes the route to arouse various emotion of the target audience. As the societal value has changed over the years, so has changed the pattern of advertisement to lure the consumer. In earlier days, when advertisindg came into picture, the society used to be closely knitted and had joint families. Hence, it was possible to capture a large audience at a go and that too with a well directed common messaage that includes the societal value of being together. As time progressed, families broken apart and nuclear families arose in the scene-so advertisers started targeting individual people\'s choices and came up with 2-3 versions of a single advertisement that can attract different customers having a same choice but with different mentality. Moreover, the division of society into high income group, middle income group and lower income group made the advertiser think in different ways.The concept of niche-advertising crept in- advertisers started targeting people based on their income. Then came the era of internet that changed the advertising objective all together. Initially the case was to attract the customer towards a product now marketers try to present their product at a place and time when customers need it, Today consumer is busy, having various options to compare - so reaching to the customer at a right time and at a right place is very necessary-so came the practice of using direct mail communication, tracking customer search history to know his/her preferences and present him/her with the exact product they want, came the concept of testimony from satisfied customer to gain confidence of other customers. Qualitative changes over the years that represents a new level of difference: - Niche advertising- Targeting preferences of individual class - Personal Targeting through internet- helped to save conumer efforts and made the experience rich..

This question refers to the ABO blood type locus. Remember that the A and B alleles are codominant to each other and both are dominant to the O allele. Assume no epistatic interactions with the H locus. A man has blood type A. Mark all genotypes below that are possible for this man. Select one or more: AA AB AO BB BO OO Solution Hence both A and B are codominant and dominant over O, the possible genotype of man having blood group A are AA and AO. Explanation: As both A and B are codominant if both are present iegenotype AB results in AB blood group BB and BO results in B blood group (as there is no A in genotype and B is dominant over O) OO results in O bllod group(Absence of both A and B in genotype).

This is testing Algorithm Writing For this assessment we will be combining while and if control structures together. (A):Write a pseudocode (pen and paper) algorithm that solves the ODE y\'= f(t, y) using Euler’s method. (B):Convert this algorithm into MATLAB syntax, as the function euler method . B1:Your inputs should be the start time t0, the end time tend, the function f, an initial condition y0 and an initial step size h. B2:If h × f(t, y) at any point exceeds 1, your function should halve the step size h. B3:Equally, if h × f(t, y) at any point drops below 0.01, your function should double the step size h. B4:You should also make sure that the final solution step doesn’t ‘overshoot’ tend. (i.e. change h during the final step to exactly reach tend). B5:Your MATLAB code should use the function header below, and be wellcommented with a sensible layout. (C)Include your pseudocode algorithm, as well as the MATLAB code in your Portfolio submission. Also include a discussion of when the code could break, or give incorrect outputs (you DO NOT need to design your code to avoid these). Solution Answer:) A) The derivative term in the first order ivp: y\' = f(t, y), y(t0) = y0 is approtimated by making use of Taylor series approtimation of the dependent variable y(t) at the point ti+1. That is y(ti+1) = y(ti+ Dt) = y(ti) + Dty\'(ti) + (Dt2 / 2)y\'\'(ti) + . . . = y(ti) + Dtf(ti, yi) + (Dt2 / 2)y\'\'(ti) + . . . (... y\'(ti) = f(ti, yi)) if the infinite series is truncated from the term Dt2 onwards, then y(ti+1) = y(ti) + Dt y\'(ti) (or) yi+1 = yi + Dt fi for all i That is, for i = 0, y1 = y0 + Dt f0 i = 1, y2 = y1 + Dt f1 ! i = n-1, yn = yn-1 + Dt fn-1 Since y0 and hence f0 are known (from initial condition) in the equation corresponding to i = 0, all the terms on the r.h.s are known. So y1 that is, y at t1 is calculated easily from this equation. Similarly once y1 is known, r.h.s of the equation corresponding to i = 1 is also known so y2 can be computed. As we proceed in the same way until i = n-1, yn can be obtained. This is an etplicit method because in any equation there is only one unknown which can be separated to the left side of the equation. Local truncation error : The error in the approtimation, that is the difference between the exact solution at ti+1 and the numerical solution yi+1 is called the local truncation error (assumed that yi+1 is calculated with exact arithmetic with out any round off error). Ti+1 = y(ti+1) - yi+1 = y(ti+1) - yi - Dtfi = h2/2 y\'(t) (by Taylor series & remainder theorem) where ti < t < ti+1. Hence the order of the local truncation error for Euler scheme is O(Dt2) as Dt -> 0.

The hepatic portal system, pulmonary circulation and fetal circulation all vary from the “normal” pattern of blood flow. Be able to describe these special cases. Solution 1. HEPATIC PORTAL SYSTEM 2. PULMONARY CIRCULATION In Pulmonary circulation, deoxygenated blood from the right ventricle is carried to the air sacs of the lungs and returns oxygenated blood from the lungs to the left atrium. In hepatic portal circulation, blood is carried from capillaries of the gastrointestinal organs and spleen to sinusoids of the liver. The liver stores, modifies, or detoxifies some of the substances that have been absorbed by the gastrointestinal tract. The hepatic portal system includes the veins that drain blood from the pancreas, spleen, stomach, intestines, and gallbladder and transport it to the hepatic portal vein. The pulmonary and systemic circulations are different in several ways: a. Blood in the pulmonary circulation need not be pumped as far as blood in the systemic circulation b. Pulmonary arteries have larger diameters, thinner walls, and less elastic tissue; consequently, resistance to blood flow is very low and therefore less pressure is needed to move blood through the lungs. c. As a result, normal pulmonary capillary hydrostatic pressure is lower than average systemic capillary hydrostatic pressure. 3. FETAL CIRCULATION Featal circulation exists only in the fetus and consists of structures that permit exchange of substances between the developing fetus and its mother. i. The fetal circulation permits the fetus to obtain oxygen and nutrients from the maternal blood and eliminate its carbon dioxide and wastes into the maternal blood. ii. The exchange of substances between the fetal blood and maternal blood occurs through the placenta, which attaches to the navel (umbilicus) of the fetus by the umbilical cord. iii. Deoxygenated blood flows from the fetus to the placenta via two umbilical arteries. iv. Oxygenated blood returns from the placenta to the fetus via one umbilical vein which delivers its blood primarily to the ductus venosus(fetal blood vessel that joins aorta and pulmonary artery) that drains into the inferior vena cava. .

Most commonly during Solution Answer : Ethanol Ethanol, C2H5OH, (also called Ethyl Alcohol) is the second member of the aliphatic alcohol series. It is a clear colourless liquid with a pleasant smell. Except for alcoholic beverages, nearly all the ethanol used industrially is a mixture of 95% ethanol and 5% water, which is known simply as 95% alcohol. Although pure ethyl alcohol (known as absolute alcohol) is available, it is much more expensive and is used only when definitely required. Preparation Ethanol is prepared as 95% alcohol (i.e. a 95% solution of ethanol in water) by distillation of the solution which results from the fermentation of sugars. Manufacture There are two major industrial pathways to ethanol. Ethanol which is intended for industrial use is made by the first method, while ethanol intended for food use tends to be made by the second method. Reaction of Ethene with Steam Most of the ethanol used in industry is made, not by alcoholic fermentation, but by an addition reaction between ethene and steam. Alcoholic Fermentation The fermentation process takes three days and is carried out at a temperature between 250C and 300C. The ethanol is then obtained by fractional distillation..

The ABO and MN blood groups are given below for four sets of parents (1 to 4) and four children (a to d). Recall that the ABO blood group has three alleles, I^A, I^B, and i. The MN blood group has two codominant alleles, M and N. When all the genetic data is considered together and by the process of elimination you should be able to match each of the four children with the correct set of parents. Solution Beginning from the first set of parents, let us try to determine the genotype of all sets. Parents 1: The father can be IBIB or IBi and the mother can be IAIAor IAi. For the MN group, The father is NN and the mother is MN. So, their children can of A, B, AB or O blood type and of either MN or N blood group. Parents 2: The father can be IAIA or IAi and the mother can be IAIAor IAi. For the MN group, The father is NN and the mother is also NN. So, their children can of A or O blood type and of N blood group. Parents 3: The father can be IAIAor IAi and the mother is IAIB. For the MN group, both the parents are of MN type. So, their children can of A, B, or AB blood type and of either M, N or MN blood group. Parents 4: The father is ii and the mother is IAIAor IAi. For the MN group, both the parents are of MM type. So, their children can of A or O blood type and of M blood group. Amongst the given set of children only one has the N type blood group. So this child (a) definitely belongs to the parents who can have children with only N blood group i.e. Parents 2. For the remaining 3 cases (b, c and d), we want parents with possibility of giving children of M type blood for children (c) and (d). Parents 1 cannot give an offspring with M type blood group, so it has to be matched with child (b) where it can easily give AB and MN blood types. For child (d), Only parents 4 are a match because that is the only set of parents from the remaining parents which can have a child with O blood group. That leaves parents 3 to give birth to child (c) with A blood group and M blood type and it is possible. So, 1- b, 2- a, 3-c, 4-d.
