28. What is the proposed role of thioredoxin in seed protein mobilization? 29. How do monocots and eudicots differ in the placement and activation of the peptidases needed to mobilize seed storage proteins? Solution 28)The role of thioredoxin in seed protein mobilization is that it leads to the reduction of disulfide bonds and they respond of active oxygen species and help in the proteing mobilization. 29)The monocots and eudicots are different. When we have a monocot seed and we open it then the stored food of the seed is present as one unit .On the other hand the Eudicots have the food source which is broken into two parts – which is referred by “di”. Moreover when the seed germinates, the monocot usually forms one seed leaf which is known as the the cotyledon while the the Eudicot forms two seed leaves Another difference is that the monocots are represented by the leaves which have parallel veins. This shows that the veins usually begin at the base of the leaf and these veins usually move parallel to one another towards the end While the Eudicots have leaves with net veins,.

Lists the stages in the development of the earth and the formation of life on earth Lists the stages in the development of the earth and the formation of life on earth Solution Earth is the only habitable planet in our solar system known so far and the process of development of the Earth play an important role in sustaining life on Earth. Many theories exist which debate on the formation of Earth. But the most plausible theory is the core accretion theory. The development of the Earth was accompanied by immense geological changes which gradually gave rise to life on this planet and eventually evolution took place. Stages in the development of the Earth Formation of life on Earth.

How exactly do Protease inhibitors help HIV patients fight the disease? Where exactly do quinolones act to prevent bacterial multiplication? Cite 4 characteristics of an ideal antimicrobial agent Solution 1.Enzyme that breaks down protein into its building blocks, amino acids, is called a protease.In an HIV virus, proteolytic cleavage of the polypeptide precursors into mature enzymes and structural proteins are catalyzed by HIV protease.HIV protease inhibitors are peptide-like chemicals that competitively inhibit the action of the virus aspartyl protease. These drugs prevent proteolytic cleavage of HIV Gag and Pol polyproteins that include essential structural and enzymatic components of the virus. This prevents the conversion of HIV particles into their mature infectious form. 2.Quinolones bind to a bacterial complex of DNA and DNA gyrase, blocking DNA replication. Quinolones such as nalidixic acid bind to the cleavage complex composed of DNA and gyrase during this strand passage. This interaction of quinolone acts to stabilize the cleavage intermediate which has a detrimental effect on the normal DNA replication process. The effects of this inhibition result in the death of the bacterial cell. The newer fluoroquinolones such as ciprofloxacin, norfloxacin, and ofloxacin also interact with DNA gyrase and possess a broad spectrum of antimicrobial activity. 3.solubility in body fluids-agent must dissolve in body fluids to be transported in the body and reach the infectious organisms selective toxicity-agents must be more toxic to microorganisms than to host cells. toxicity not easily altered-agent should maintain a standard toxicity and not be made more or less toxic by interactions with foods and other drugs or abnormal conditions such as diabetes and kidney disease in the host nonallergenic-agent should not elicit an allergic reaction in the host stability-maintenance of a constant, therapeutic concentration in blood and tissue fluids, agent should be sufficiently stable in body fluids.

Fred, Tom, Jenny and Sarah pooled their money and purchased a packet of jellybeans. Tom received twice as many jellybeans as Fred while Sarah received tour less than Tom. Jenny was given a third of the number of jellybeans that Sarah received. How many jellybeans did each of the children receive if there were 40 jellybeans in the packet? Solution Let Fred has x jellybeans.so tom has 2x , sarah has 2x-4 , jenny has (2x-4)/3 jellybeans.since they total have 40 jellybeans then x + 2x + (2x-4) + (2x-4)/3 = 40 => 3x+4(2x-4)/3=40 =>17x-16=120 =>x=136/17=8 so fred has 8,tom has 16,sarah has 12 & jenny has 4 jellybeans..

Explain the various categories of ratio analysis and provide examples of at least two ratios in each category. If you were an investor, which category would you be most interested in? Why? Solution Part-1 Ratios are used by lenders and business analysts to determine a company\'s financial stability and standing.It\'s important to understand that financial ratios are time sensitive; they can only show a picture of a business at a given time. There are five catagories of Financial ratios and those are as follows : Part-2 : There are a large variety of ratios out there, but for an investor using financial ratios which are broken up into four major categories: profitability ratios, liquidity ratios, solvency ratios and valuation ratios. As an investor he should consider Profitability ratio because Profitability ratio is a key piece of information that should be analyzed when you\'re considering investing in a company. This is because high revenues alone don\'t necessarily translate into dividends for investors unless a company is able to clear all of its expenses and costs. In general, the higher a company\'s profit margin, the better, but as with most ratios, it is not enough to look at it in isolation. It is important to compare it to the company\'s past levels, to the market average and to its competitors. Profitability Ratios : The profitability ratios are just what the name implies. They focus on the firm\'s ability to generate a profit and an adequate return on assets and equity. They measure how efficiently the firm uses its assets and how effectively it manages its operations and answers questions like how efficiency his business and it helps to compare with other competitor. Examples of Proftitablity ratios are Gross profit ratio, Net profit ratio, Operating profit ratio and Return on investment ratio. Market Value Ratios : The market value ratios can be calculated for publicly traded companies only as they relate to stock price. There are many market value ratios, but a few of the most commonly used are price/earnings (P/E), book value to share value and dividend yield . LEVERAGE RATIO /Capital Structure ration : The term capital structure refers to the relationship between various long term forms of financing such as debentures (long term), preference share capital and equity share capital including reserves and surpluses. Leverage or capital structure ratios are calculated to test the long term financial position of a firm. Generally capital gearing ratio is mainly calculated to analyse the leverage or capital structure of the firm. Example of ratios are total debt ratios, the debt/equity ratio, the long-term debt ratio, the times interest earned ratio, the fixed charge coverage ratio, and the cash coverage ratio. Asset Efficiency or Turnover Ratios : The asset efficiency or turnover ratios measure the efficiency with which the firm uses its assets to produce sales. As a result, it focuses on both the income statement (sales) and the .

Compare and contrast swabs and contact (RODAC) plates for their ability to enumerate bacteria and viruses from surfaces. (Consider the question carefully, it is a bit of a trick question). Solution Swabs and contact (RODAC) plate methods are use for surface sampling for all microorganisms. In Swabs method, we use sterile cotton or calcium alginate swabs for small surfaces and Sponges for big surfaces to pick microorganisms and transfer them to broth nutrient medium. This method is easy to use, Inexpensive and can apply to any surfaces. The main disadvantage of this method is microorganisms’ recovery is very poor and collectable in broth medium only. In contact plate or RODAC plate method, the whole plate is pressed against the surface of chosen and then collect microorganisms. RODAC abbreviates for Replicate Organism Detection and Counting. This method is usable to smooth surface very efficiently and nutrient medium flexible. The main disadvantage for this method is, overgrowth occurs if surface is highly contaminated..

Briefly explain the ventral and dorsal body cavities and the membranes which line the ventral cavities. What is a mesentery? Solution The ventral body cavity is a body cavity that is in the anterior (front) aspect of the body. It is made up of the thoracic cavity, and the abdominopelvic cavity. The abdominopelvic cavity is further divided into the abdominal cavity and pelvic cavity, but there is no physical barrier between the two. The abdominal cavity contains digestive organs, the pelvic cavity contains the urinary bladder, internal reproductive organs, and rectum. The thoracic cavity is separated from the abdominopelvic cavity by the diaphragm. The thoracic cavity is further separated into the pleural cavity which contains the lungs and the superior mediastinum which includes the pericardial (heart) cavity. The organs within the ventral body cavity are called the viscera. The walls of the ventral body cavity and outer covering of its organs contain a thin covering called the serosa (also called serous membrane). It is a double-layered membrane made up of two parts called the “parietal serosa” (lines the cavity walls) and “visceral serosa” (covers organs in the cavity). The serous membranes are separated by a thin layer of fluid called “serous fluid“. Serous fluid is secreted by both membranes and acts as a lubricant, allowing organs to slide in the cavity without causing friction. The dorsal body cavity is located along the dorsal (posterior) surface of the body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord. The two cavities are continuous with one another. The cranial cavity is a large, bean-shaped cavity filling most of the upper skull where the brain is located.The vertebral cavity is a very narrow, thread-like cavity running from the cranial cavity down the entire length of the spinal cord. Just as the brain and spinal cord make up a continuous, uninterrupted structure, the cranial and spinal cavities that house them are also continuous. The brain and spinal cord are protected by the bones of the skull and vertebral column and by cerebrospinal fluid, a colorless fluid produced by the brain, which cushions the brain and spinal cord within the posterior (dorsal) cavity. The covering and protective membranes for the dorsal body cavity are called meninges..

Write a 250-300 word abstract explaining that the internet is the greatest acheivement in the 21st century. It was not invented in the 21st cenury but it has mainly become significant in the 21st century. USE IEEE format. Thank you! Solution The Internet is, obviously, one of mankind’s greatest accomplishments in this Information Age. But this new technology not only saves time—it wastes it too. It makes life simpler, yet more complicated; it brings us together, yet pushes us apart. Now that is a paradox! Internet is one of the great advances not only of our current culture, but of any culture at any point in history. The Internet allows for better documentation of the world around us, and we are slowly getting closer to a completely accurate documentation of history. Heffernan compares prior historical documentation to the crackle of vinyl records: they are a representation of reality created by humans but with a low fidelity to reality itself. Technology, including the internet, is slowly evolving to be better at documenting what life is like. There are 4D movies, iPhones that can create holograms, and apps to document police encounters (such as Hands Up) or put dog ears on a selfie (Snapchat.) As Mark Fischbach, online Youtube personality known as Markiplier, said back in December, 2014: “The global, shining goal of the Internet is to combine everybody and to let everyone talk with everyone, and unite, and make cool stuff together. I didn’t know it would happen this quickly.” He’s quite right. The Internet works best when everyone can contribute, and it lets people across the world interact and learn about other cultures, and other ways of thinking. Just a few decades ago, sound in movies was a brand new thing, and color wasn\'t even thought of. It was not that long ago that historians filmed real life Civil War veterans doing the now famous rebel yell. As Heffernan points out, the Internet and similar technologies are just illusions of pure documentation, like video of Civil War vets. What\'s more, the Internet is just getting better... Our troubles and calamities have not just doubled; they’ve multiplied—thanks to modern technology! But our God has allowed modern communication methods to dramatically increase. The Internet is bridging the gap that He put in place some 4,000 years ago. Already, the minds of the people of the nations of the world have been drawn closer together—and now, with the help of the digital information superhighway, man has turned earth into a “global village.” With this invention he’s not only collapsed distance; he’s demolished all inhibiting boundaries..

Why is it recommended that vegans take an oral vitamin B12 supplement? Provide a detailed answer and back up with research. Solution Vitamin B12 or cyanocobalamin- it is a water soluble vitamin so it does not stay in the body for long time, thus required from dietary intake or supplements. Sources- liver, fish, shellfish, crabs, tofu, soy milk, egg, dairy products, red meat, cheese etc. Importance of vitamin B12- It is observed in various studies that Vegetarians or vegans whose dietary intake does not contain vitamin B12- rich food items are usually deficient in vitaminB12 and hence are prone to diseases like- Depression Constipation Confusion and dementia Cardiovascular diseases Neurological and mood disorders Bone disorders According to a study published online by Kaam S Woo, et al,i n the journal Nutrients, vegans especially Indians and Chinese are more likely to suffer from metabolic vitamin B12 deficiency. Also strict vegetarians ( those who totally avoid consumption of eggs and dairy products) are even more vulnerable to vitamin B 12 deficiency, which eventually affects or alters the arterial endothelial function and carotid-intima-media thickness (changes in these 2 parameters leads to atherosclerosis). Further, the deficiency can also lead to neurological disorders like dementia etc. Thus it is recommended to vegans to consume food fortified with vitamin B12, diary products and vitB12 supplements. Regular checkup for serum level of vital B12 is mandatory to avoid any risks that are associated with its deficiency..

Often associated with metabolic acidosis, this breathing pattern is compensatory as it attempts to blow off excess CO2 build up in body Kussmaul is respiratory compensation for a metabolic acidosis, most commonly occurring in diabetics in diabetic ketoacidosis. Blood gases on a patient with Kussmaul breathing will show a low partial pressure of CO2 in conjunction with low bicarbonate because of a forced increased respiration. Kussmaul breathing develops, as the acidosis grows more severe..
