Why would it be advantageous to be able to become an endospore if you were a soil bacterium? A water bacterium? A pathogen? (answer each individually - think about the environmental stresses these bacteria are under; 3 points) Solution Endospore is a tough resistant, protective layer, which keep the cell in the dormant state under unfavorable conditions of growth. For example, in tundra soils, the bacteria form endospores during the cold summers and become active during the warmth summers when the temperature allows their active metabolism. Eg: Bacillus species. Endospore formation is advantageous to water bacteria because the decreased water levels or dried water sources does not favour their growth. The bacteria become active again when the water is available. Eg: Clostridium species. Pathogenic bacteria can from endospores in response to toxicity of drugs and radiation. These bacteria become active in the absence of these stressors. For example, Mycobacterium tuberculosis..

What is black hole? Solution A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star\'s life. Some black holes are a result of dying stars. Because no light can escape, black holes are invisible. However, space telescopes with special instruments can help find black holes. They can observe the behavior of material and stars that are very close to black holes..

We are interested in determining whether scale traits for the Rio Grande Horned Toad follow a common epistatic relationship. The observed phenotypes are scaled and fused. Which mode of inheritance would mostlikely explain the data below? Phenotype Scaled 122 Fused 98 Total 220 Select One: dominant/recessive epistasis deuplicate dominant epistasis duplicate genes with cumulative effect single dominant epistasis single resessive epistasis duplicate recessive epistasis Solution The correct answer is :dominant/recessive epistasis. Reason: In this case,dominant allele in both homozygous and heterozygous conditions and recessive allele in homozygous condition at each defined locus will give rise to same effect i.e scaled phenotype while other genotypes will produce fused phenotype..

The respiratory gases of animals are . oxygen and nitrogen. nitrogen and carbon dioxide. oxygen and carbon dioxide. Solution Answer: oxygen and carbon dioxide. Reason: Animals are vertebrates and perform their metabolic reactions using oxygen to generate ATP as energy in mitochondria in which oxygen is the chief electron acceptor finally CO2 is generated as metabolic waste product finally eliminated in the form of bicarbonate or expiration via lungs.

2.) Explain the origin/evolution of viruses by these hypotheses: reductive, additive, horizontal gene transfer, and common ancestor. Why are there so many different ideas? Is there any one right answer? Why? Solution Origin of virus has been hypothesized by three main views: 1. Reductive hypothesis: This states that viruses were initially small parasites of large cell. Just like parasites, they used to take nutrition from the host; and left the host when host\'s body became diseased and useless for the virus. This hypothesis is also known as degeneracy hypothesis. This hypothesis is not accepted much, especially in case of large viruses like pox virus. Moreover, no parasites on earth resemble viruses at all. 2. Additive hypothesis: Complex protein and nucleic acids combined together to form the infectious agents, i.e. viruses. This hypothesis is also known as virus-first hypothesis. In this hypothesis, the actual definition of virus is totally changed. Why couldn\'t the genetic material of replication machinery combine together during the course of evolution; even after being more fit than the rest of the genetic material? 3. Horizontal gene transfer: Small bits of RNA or DNA escaped from large organisms and then underwent homologous recombination; to form infectious agents known as virus. The process was random. This is also known as escape hypothesis. This hypothesis was not accepted much because it could not explain the formation of capsid around the genetic material. So many different answers are there, because the genetic material of virus is of different types like ssRNA (+ and -), dsRNA (+ and -), ssDNA, dsDNA etc. This is not the case with cellular organisms like prokaryotes and eukaryotes. All of them have dsDNA as genetic material. Now, because of different genetic material, it is very difficult to trace the common ancestor of all viruses. Therefore, different researchers have proposed different hypothesis from time to time. None of these hypotheses has been accepted. One right answer is Common ancestor hypothesis. This states that there must be some common ancestor from which all viruses originated..

Priority queues may to implemented as linked lists kept in key order, or linked lists kept unordered compare the cost for the implementation of the operation of Inserting a new key Changing a key value Deleting the maximum Key We\'ve implemented a FIFO queue With the usual structures and algorithms. Now we add reverse links to each node. Does the Order of queuing or dequeuing change? Solution 1)Queue is a First In First out data structure and one of the way to implement is linked list with order and unorder. So, lets first talks aboit the order liked lists: For example linked list is Increase order that highest element is at first and least element is at last. and deletion of elements takes place at last and inserting of elements is taking at first we can think in reverse also. To insert an element we need to travrse all the list to the required osition to insert the element , If N elements are in the list then for AVERAGE and Worst time cases takes O(N) time and for Deletion also takes O(1) time whcich is constant. and in the case of changing any elements it is same as the inserting element becase in first step element needs to be found and in second step value neeeds to be changed. IN UNORDER list case The INSERTION and DELETION takes O(1) time only. and for changeing it is O(N) in average and worst time complexities. 2)No it depends on the way we does those operations. I mean that If to wish to do insertion at last and deletion at first and vice-verse that upto you to code. but if links are changed all the meaning of your first code also changes. I think you got my point..

People with long-standing diabetes have a greater risk of developing pancreatic cancer when compared with those who do not have diabetes. This is an example of:An epidemiological fallacy Solution Ans D Epidemiological association 80% people having pancreatic cancer have either glucose intolerance or diabetes. Now there can be 2 possibilities, either cancer caused the associated diabetes or the long standing conditions caused the pancreas to have cancer. Recent studies and investigations supports both the hypothesis. So there is an epidemiological association between them..

Modigliani and Miller disagreed with the proposal by Gordon and Lintner regarding dividends. Why? M&M claimed that many, if not most, investors will spend their dividends on consumer goods. M&M claimed that many, if not most, investors will reinvest their dividends in the same or similar manner that the firms would. M&M claimed that many, if not most, investors would prefer capital gains. M&M claimed that firms only attract investors who would prefer dividends. Solution . 1.An intuitive understanding of MM dividend irrelevance from the concept of a homemade dividend. Means an investor can sell of their shares to generate cash flow. 2.

1) A female student suffers from anorexia nervosa. One afternoon she is rushed to the emergency room because of an irregular heartbeat. Her breath has the smell of an aromatic hydrocarbon (fruity). Blood and urine samples reveal ketonemia and ketonuria, respectively. Why do you think she is having the irregular heartbeat? Helpful hint: As the kidneys excrete excess H+, they reabsorb K+.

How do they happen? What happens that causes a concussion? Examples of symptoms of concussions? Are there examples of people who have suffered concussions in popular culture? Look up well documented cases of famous athletes example E_ic Lindros. Solution Concussion is mild traumatic brain injury that results from a blow to the head, or a fall, or any injury that shakes the brain inside the skull. The brain temporarily loses some of its functions. * The physiology behind concussions is either stretching of axons or changes in the flow of ions in the neurons. * Symptoms are either behavioral or cognitive, but physical symptoms of damage are rare to diagnose. Amnesia, loss of conciousness, impaired congnition skills, headache, and emotional changeability are the most common symptoms..
