Siderophors are iron-binding agents that transport iron into cells. Although there are structural differences among different siderophores they generally all share the property of: A. binding extracellular ferrous iron (in its +2 oxidation state) and releasing it in the cytoplasm of the cells as ferric iron (in its +3 oxidation state). B. binding extracellular ferric iron (in its +2 oxidation state) and releasing it in the cytoplasm of the cell as ferrous iron (in its +3 oxidation state). C. binding extracellular ferric iron (in its +3 oxidation state) and releasing it in the cytoplam of the cell as ferrous iron (in its +2 oxidation state). D. binding extracellular ferrous iron (in its +3 oxidation state) and releasing it in the cytoplasm of the cell as ferric iron (in its +2 oxidation state). Solution C. binding extracellular ferric iron (in its +3 oxidation state) and releasing it in the cytoplam of the cell as ferrous iron (in its +2 oxidation state). They foem tight and stable complexes with ferric ion..

Intravenous Pyelogram Reason for exam: Fever of unknown origin Technical data: no-known allergies. 100 milliliter infusion through iv. No reaction noted. Intravenous Pyelogram: Following the intravenous injection of contrast material, several films were taken including anterior-posterior and oblique views showing that both kidneys are normal in size and configuration. The visualized course of the distal ureters are both normal. The bladder is well visualized on a delayed film and is within normal limits. There is a small amount of urinary residual on the post voiding film. Conclusion: Essentially normal intravenous pyelogram. Answer: Solution As the patient was suffering from fever of unknown origin. The possible cause of fever was assumed to be kidney infection (Acute pyelonephritis), urinary tract infection or bladder infection. So to have a clear idea the Intravenous Pyelogram was performed. It is an x-ray examination in which an injection of contrast material is used to evaluate the kidneys, urinary bladder and ureters. Since the reprts of intarvenous pyelogram was normal, the origin of fever is not the urinary system. Now the doctor can diagnose other organs to locate the origin of fever..

if you use the command sudo iptables -L -v you will notice that FORWARD policy hasn’t seen any traffic. Discuss a scenario where this policy will be used Solution The INPUT chain specifies changes to packets as they are processed, but after the PRE ROUTING chain is traversed. The POST ROUTING chain specifies changes to packets as they are exiting the firewall, after the OUTPUT chain is traversed.The FORWARD chain specifies changes to packets that are forwarded through the firewall. The OUTPUT chain specifies changes to locally generated outgoing packets. information is available about packet marking in the iptables documentation, beyond that it’s used by the Linux Quality of Service implementation and that it’s intended as a communication flag between iptables modules. Scenarios and scenario techniques are also distinguished by the type of information which they can and should assimilate and/or transport. Are qualitative descriptions alone used r the generation of scenarios depending on whether quantitative or qualitative data are required, meaningful, and available. Quantitative knowledge is used, for example, in topic areas like demography and economics, whereas on the other hand cultural, institutional or political dimensions often tend to be recorded qualitatively ,The methodological decision for proceeding either qualitatively or quantitatively has direct consequences regarding the possible degree of formalization of the scenario technique to be used. To put it provocatively and ideal-typically, quantitative approaches have recourse to mathematical models, qualitative approache on the other hand have recourse to narrative and literary techniques..

How did the Great Awakening inspire ordinary citizens to assert their right to independent judgement? Did the movement expand freedoms? Solution Answer:- Great awakening inspired ordinary citizens. Great Awakening was a series of Christian revivals that swept Britain and its American Colonies between the 1730s and 1740s. The revival movement had a permanent impact on Protestantism as adherents strove to renew individual piety and religious devotion. The Great Awakening marked the emergence of Anglo-American evangelicalism as a trans denominational movement within the Protestant churches. In the United States, the term Great Awakening is most often used, while in the United Kingdom, it is referred to as the Evangelical Revival. Great awakening inspired people to fight for freedom. The Awakening played a major role in the lives of women, though they were rarely allowed to preach or take leadership role Great Awakening changed in Americans\' understanding of God, themselves, the world around them, and religion. In the southern Tidewater and Low Country, northern Baptist and Methodist preachers converted both white and black people. Some were enslaved at their time of conversion while others were free. Caucasians began to welcome dark-skinned individuals into their churches, taking their religious experiences seriously, while also admitting them into active roles in congregations as exhorters, deacons, and even preachers..

Charles Darwin Origin of Species 3. Discuss the difficulties with sterility of organisms under captivity. 4. Why do organisms that are closely related look different? 5. How important is the environment to growth of organisms? Solution 3). The animals under human care, otherwise known as organisms under captivity can be turned sterile if they are the hybrids containing two different sets of chromosomes. So, no breeding between the animals is possible and all the animals are produced mostly from one origin. This could contribute to the termination of that particular species and also alter the biodiversity..

Determine one (1) advantage to selecting an S corporation status. Provide a rationale for your advantage. Determine one (1) disadvantage to selecting an S corporation status. Provide support for your determination. Solution one (1) advantage to selecting an S corporation status: Limited liability: Company directors, officers, shareholders, and employees enjoy limited liability protection. An S corporation protects the personal assets of its shareholders. Absent an express personal guarantee, a shareholder is not personally responsible for the business debts and liabilities of the corporation. Creditors cannot pursue the personal assets (house, bank accounts, etc.) of the shareholders to pay business debts. In a sole proprietorship or general partnership, owners and the business are legally considered the same—leaving personal assets vulnerable. one (1) disadvantage to selecting an S corporation status. Provide support for your determination: Formation and ongoing expenses. To operate as an S corporation, it is necessary to first incorporate the business by filing Articles of Incorporation with your desired state of incorporation, obtain a registered agent for your company, and pay the appropriate fees. Many states also impose ongoing fees, such as annual report and/or franchise tax fees. Although these fees usually are not expensive, and can be deducted as a cost of doing business, they are expenses that a sole proprietor or general partnership will not incur..

Delegate: \"The role members of Congress serve in representing the interests and policy preferences of their constituents\" (Zaino, 2012, p. 66) Trustee: \"The role members of Congress serve in acting on behalf of the interests of the home constituents and nation regardless of whether constituents would immediately approve of the members\' decisions\" (Zaino, 2012, p. 66) An example of how these two perspectives (delegate and trustee) may conflict is when the legislator is asked to vote on the closing of a military base in his/her district where it may be good for overall society to minimize the expense of the base but in that legislator’s district it may cause the loss of jobs. A trustee may be more willing to close the base where a delegate would not. Most legislators try to balance the two types of representation. The discussion question(s) is: If you were a legislator and had to decide whether to close the base or not, what would you decide? Are you acting more as a delegate or a trustee in making your decision? Explain your response in detail please. Solution If I am the legislator, I would decide to close down the military base but not at once. As a representative of the people of the constituency, I should not go against the betterment of my own constituency. On the other hand, I should take care of national benefit. But I will act more as a delegate. In the delegate model, constituents elect their representatives as delegates for their constituency. These delegates act only as a mouthpiece for the wishes of their constituency, and have no autonomy from the constituency. On the other hand, in the trustee model constituents elect their representatives as trustees for their constituency. These \'trustees\' have sufficient autonomy to deliberate and act in favor of the greater common good and national interest, even if it means going against the short-term interests of their own constituencies. The military base is an economic actor—a direct employer, a keystone industry and a hub of social and cultural interactions. Military bases across are firmly entrenched in the local economies that they adjoin. Close a major military base implies dozens of small businesses associated with it may as well close down. As a result, families will be forced to relocate and whole towns may fail partially. On the other hand, military installations pay no taxes. Military expenses would become burden for the society at large. So closing military base would reduce the financial burden. So instead of closing down the entire military base at once, I will prefer partially reduce the expenses of the military base. This will allow the people of the locality to get the opportunity to adjust and find alternative sources of earning..

An earthquake measuring 6.4 on the Richter scale struck Japan in July 2007, causing extensive damage. Earlier that year, a minor earthquake measuring 3.1 on the Richter scale was felt in parts of Pennsylvania. How many times more intense was the Japanese earthquake than the Pennsylvania earthquake? (Round your answer to the nearest whole number.) times Solution M = log(I/S) where S is the intensity of std eartquake. 6.4 = log(I1/S) 3.1 = log(I2/S) subtracting 2nd from 1st: 6.4 -3.1 = log(I1/S) - log(I2/S) 3.3 = log(I1/I2) I1/I2 = 10^3.3 I1 = 1995I2 So, eartquake in Japan was 1995 times stronger than eqrtquake in Pennsylvania.

A veterinarian amputated a swollen testicle from a zebra at a zoo and discovered that the testicle contained a molar tooth, complete with long roots. What is the most likely explanation? A.The genes that govern the growth of teeth moved from the zebra\'s mouth down to his testicle. B.The genes that govern the growth of teeth were duplicated too many times during cell division. C.The genes that govern the growth of teeth were accidentally turned on in the cells of the testicle. D.A gene that normally governs the production of sperm mutated into a gene coding for teeth. E.Another zebra had bitten the testicle, and the tooth got embedded in the flesh. Solution Answer is C. In multicellular organisms, all cells comprises same genetic composition but the expressed portions are different in different types of cells. This is called cell or tissue specific expression. Some times due to some mutations, the genes which acctually not expressed in that cells are also expressed. This is thecalled reason for abovedifferences condition.

Albinism. Some might wonder why this disorder doesn\'t \"phase out\" of the gene pool over time? Why do people from different parts of the world have different colored skin? Why do people from the tropics generally have darker skin color that those who live in colder climates? Solution Albinism:It is a complete or partial absence of pigment in skin hair and eyes. it causes skin cancers and skin burns due to lack of pigmentation and a number of vision defects.albinism also called achromasia. GENEPOOL:It occurs due to recessive genes passed from both parents,it is due to absence of tyrosinase enzyme(it contains copper for the production of melanin).there are other genetic mutations which are be associated with albinism. DIFFERENT PARTS OF THE WORLD HAVE DIFFERENT COLOURED SKIN: People have different coloured skin due to different types of climates in different parts of the world,people who live in the tropic side have darker skin then people who live in the colder countries.but the colour of the people is determines by a pigment caled mealanin.people with dark skin has more melanin, melanin protects the body from harm ful uv radiations.people with light pigmentation have less melanin. PEOPLE IN THE TROPICS GENERALLY HAVE DARKER SKIN THEN PEOPLE WHO LIVE IN COLDER COUNTRIES: People who live in the tropics are more exposed to harmful uv radiation so the body produce more melanin to protect the skin from harm ful uv radiations.In colder climates there is no harmful uv radiations,so the people has light skin colour..

A concave mirror forms an image on a screen that is twice as large as the object. Both the object and the screen are then moved to produce an image on the screen that is three times the size of the object. If the screen is moved 75 cm in the process, how far is the object moved? What is the focal length of the mirror? Solution magnification: m = hi / ho = di/do hi = size of the image ho = size of the object but, hi = 2* ho, so m = 2*ho / h o = 2, Then di= 2*do mirror formula: 1/ f = 1/do + 1/di 1/f = 1/do + 1/2do 1/f = 3/2do new magnification is m \' = 3, so distance moved by the screen is s = 75 cm new image distance: di \' = di +s do\' =do-s\' then, m \' = di\'/do\' = di +s /do-s\', therefore, 3(do-s\') = di +s new focal length: 1/ f = 1/do \' + 1/di\' 1/f = 1/ do-s\' + 1/3(do-s\') solve the above equations, we get, s\' = do /9 thus, do =112.5 cm, hence, s\'= 112.5cm /9 =12.5 cm therefore, the focal length: f = 3/2do = 75 cm.

Concisely, how may HDL metabolism and the onset of type-II diabetes be correlated? What\'s the evidence? Solution Chylomicros are the major lipoprotein components of dietary lipids, which primarily enable synthesis of triacylglycerol components of low-density lipoproteins, high-density lipoproteins, very low-density lipoproteins finally followed by synthesis of cholesterol esters and cholesterol by Mevalonate pathway. The individuals who have been suffering from type 2 diabetes are associated with high lipid profiles of High-density lipoproteins (HDL) and these can be examined by higher HDL clearance. These aspects can be evidenced by the calculating “apoA-1” and “apoA-2” kinetics. It has clearly illustrated that these is significant correlations between the HDL clearance & plasma levels of glucose in type 2 diabetes patients.

Write about the following ethics case studies 1. Hyatt Regency Walkway Collapse 2. TV Antenna Collapse 3. Trench Failure 4. Three Mile Island 5. Tacoma Bridge Solution (1) Hyatt Regency Walkway Collapse :- On July 17, 1981, the Hyatt Regency Hotel in kansas City, Missouri, held a videotaped tea-dance party in their atrium lobby. With many party-goers standing and dancing on the suspended walkways, connections supporting the ceiling rods that held up the second and fourth-floor walkways across the atrium failed, and both walkways collapsed onto the crowded first-floor atrium below. The fourth-floor walkway collapsed onto the second-floor walkway, while the offset third-floor walkway remained intact. As the United states\' most devastating structural failure, in terms of loss of life and injuries, the Kansas City Hyatt Regency walkways collapse left 114 dead and in excess of 200 injured. In addition, millions of dollars in costs resulted from the collapse, and thousands of lives were adversely affected. (2) TV Antenna Collapse. :- Total collapse during installation of a 6-ton FM antenna being placed on a new 1800 ft. tower. 5 technicians killed, 3 on the hoist and 2 on the tower. It was determined that insufficient sized bolts on a makeshift lifting lug extension failed. The falling debris severed one of the tower\'s guy wires, causing the tower to collapse. The following case is based on an actual incident. However, individual actors and company names have been changed due to possible pending litigation. In addition, although conversations and memorandums used are based on evidence surrounding the case, they are hypothetical in nature, and are used to illustrate important issues rather than to attempt an actual reenactment of what \"really\" happened. In 1982, a television station video crew was filming the raising of their new television tower. The antenna was designed and manufactured by Antenna Engineering, Inc., a moderately-sized local firm. Riggers, Inc., a small local firm, was contracted to raise and assemble the antenna. During the initial design, Antenna Engineering submitted antenna plans to Riggers for their approval. Riggers approved the plans which provided for placement of the antenna hoisting lugs. These lugs provided attachment points for lifting cables which would be used for removing the antenna sections from the delivery truck, and for hoisting the antenna into the air for final assembly on a 1000 foot tower. A crew of riggers who had constructed such towers for many years was on-site. The crew used a vertically-climbing crane mounted on the already constructed portion of the tower to lift each new section of the tower, and finally, the two-section antenna onto the top of the tower. The design called for a three-legged tower, and as each new section was lifted, it was positioned and bolted onto the previous tower sections, one piece at a time. The tower legs were solid steel bars with 8 inch diameters. The tower sections we.
