The linked list implementation of the queue is derived from the STL template class___. Solution Standard Template Library (STL) – Provides a class to implement a queue in a program. Linked implementation of a queue – Simplifies special cases of the array implementation a doubly linked list; elements are not stored in contiguous memory. Opposite performance from a vector. Slow lookup and access (linear time), but once a position has been found, quick insertion and deletion (constant time). a singly linked list; elements are not stored in contiguous memory. Opposite performance from a vector. Slow lookup and access (linear time), but once a position has been found, quick insertion and deletion (constant time). It has slightly more efficient insertion, deletion and uses less memory than a doubly linked list, but can only be iterated forwards. It is implemented in the C++ standard library as forward list..

Corhin Eckles and Connor Hayes have recieved walkie talkies for Christmas. If they leave from the same point at the same time, Corhin walking north at 2.5 mph and Connor walking east at 3 mph, how long will they be able to talk to each other if the range of the walkie-talkies is 4 mi? Solution Corhin DATA: distance= x miles; rate=2.5 mph; time=d/r= x/2.5 Connor DATA: distance= y miles; rate=3 mph; time=y/4 EQUATIONS: 1) x^2+y^2=4^2 2) x/2.5 = y/4 Using 2) you get y=4x/2.5 Substitute into 1) to get x^2+(4x/2.5)^2=16 x^2+(16x^2/6.25)=16 6.25x^2+16x^2=16(6.25) 22.25x^2=100 x^2=100/22.25=4.49... x=2.12 hrs. x/2.5= 0.85 hrs. = 50.87 minutes This is Corhin\'s time, but it is the same for Connor..

Consider three genes in a hypothetical bird. One controls the color of feathers on the top of the head (red or brown), one controls the color of feathers on the chest (black or brown) and one controls the number of syllables in the song (3 or 4). You notice that birds frequently have either red heads and black chests or brown heads and brown chests, but very few have red heads and brown chests or brown heads and black chests. However, there doesn\'t seem to be any association between the syllables in the bird song and color. In other words, red heads are equally likely to sing songs with 3 or 4 syllables, and the same goes for the brown heads. Based on what you know about how the genome is organized and passed down to the next generation, explain this observation. Solution The observation can be attributed to the mechanism of genetic linkage. It is a well known fact that genes get passed from one generation to another. Mendel\'s second law of inheritance states that during this process, the inheritance of one gene is independent of the inheritance of another gene. Howeve, this law holds true only when the different genes are sufficiently spaced apart from each other. Inother words, if the genes are close to each other, it is difficult for them to be inherited in an independent manner. If one of the genes is inherited, then the other gene (by virtue of its proximity to the first gene) also tends to get inherited. This phenomenon is called as genetic linkage, and the genes involved are said to be Linked Genes. The same mechanism is in action in the above case. The genes for Red Head and Black Crest are linked, as are the genes for Brown Head and Brown Crest. Therefore, these two genes are inherited in a linked manner, and not in an independent manner. The two genes therefore behave as One Single Gene. The gene for song syllable is at a sufficient distance from the linked genes, and follows Mendel\'s law of independent assortment and is not dependent on the presence or absence of the former two traits..

are organic compounds that bind very tightly to iron ions for transport into cells. Solution Organisms like bacteria secrerte substances called siderophores which bind to iron for transport inside the cell. Iron is one of the important micronutrients for the bacterial metabolism. Ferrichrome,Desferrioxamine B and Desferrioxamine E are some of the important siderophores secreted by various bacteria..

Book: Business It\'s Legal, Ethical, Global Environment 10th Edition Page 204-205 Question and Problems # 2 #5 Solution Ethical issues connect intimately with economic issues. Take the economic practice of doing a cost-benefit analysis. You could spend one hundred dollars for a night on the town, or you could donate that one hundred dollars to the reelection campaign of your favorite politician. Which option is better? The night on the town increases pleasure. A politician’s successful campaign may lead to more liberty in the long term. We regularly make decisions like this, weighing our options by measuring their likely costs and likely benefits against each other. This connects economics directly to a major issue in ethics: By what standard do we determine what counts as a benefit or a cost? A list of competing candidates for the status of ultimate value standard includes happiness, satisfying the will of God, long-term survival, liberty, duty, and equality. Economists implicitly adopt a value framework when beginning a cost-benefit analysis. Different value commitments can lead to the same item being considered a cost from one perspective and a benefit from another. For example, those whose standard of value is increasing human happiness would count a new road to a scenic mountain vista as a benefit, while those whose standard is maintaining an unchanged natural environment would count it as a cost. The results of economic analysis also lead directly to ethical issues. For example, one result of the nineteenth- and twentieth-century debate over capitalism and socialism is a general consensus that capitalism is effective at producing wealth and socialism is effective at keeping people poor. Advocates of capitalism use these results to argue that capitalism is good; others might respond that “socialism is good in theory, but unfortunately it is not practical.” Implicit in the capitalist position is the view that practical consequences determine goodness. By contrast, implicit in the position of those who believe socialism to be an impractical moral ideal is the view that goodness is distinct from practical consequences. This connects economics to a second major issue in ethics: Is goodness or badness determined by real-world practical consequences or by some other means, such as revelations from God, faith in authorities or authoritative institutions, appeals to rational consistency, felt senses of empathy, or an innate conscience? The point for economic analysis, most of which is a matter of understanding and predicting the consequences of various actions, is that the relevance of economic analysis to policymaking depends, in part, on what one believes is the final source of value standards..

According the United States (U.S.) Centers for Disease Control and Prevention, in 2015 influenza and pneumonia combined were the 8th leading causes of death (55,227 deaths in total) and the only communicable diseases ranked among the top ten killers in the U.S. What were the 10 causes of mortality in the U.S. in 1900 and 2015? Since communicable disease caused a relatively few deaths in the U.S. in 2015, why should public and public health professionals be concerned about them anymore and devote resources in their prevention and control? Solution Top 10 leading causes of deaths in US: Hearts diseases Cancer Airway diseases which are non infectious Cardio vascular disorders Accidents Alzheimer\'s disease Diabetes Pneumonia or influenza Nephropathys Suicide. The period of communicability is less for the communicable diseases, hence they are prevention of disease in early stages is possible. Prevention and control of influenza: Good ventilation of public buildings Encouraging sufferers to cover their faces with a handkerchief when coughing and sneezing Stay in home at the first sign of influenza Vaccination against the influenza, may be killed or level attenuated vaccines Prevention of exposure to influenza strains by hygiene practice Antiviral drugs like amantadine or rimantidine used Prevention and control of pneumonia: Pneumococcal pneumonia vaccination, PPV 23 AND PCV7. Education of mother to observe the sings of pneumonia. History taking and clinical examination are very important for management Physical examination for, breath count, chest indrawing, listen for stridor, wheezing and for severe malnutrition, cyanosis Any signs detected, they are treated early by antibiotics and other measures Improving the primary medical care services and development..

9. For some non-Mendelian inheritance patterns, the genotype of an individual is not sufficient to predict the phenotype. For the following traits, what else do you need to know to predict the phenotype? a) Snail coiling direction b) Angelman syndrome due to deleted UBE3A gene Solution The inheritance mechanisms of both snail coiling and Angelman syndrome involve strong maternal influences. Snail coiling direction is governed by the genotype of the oocyte, not of the zygote, so much so that the snail coiling direction can be predicted from the maternal genotype alone. Similarly, Angelman syndrome (due to deletions in ube3A) is governed by the maternal copy of the gene alone. If the copy of the gene derived from the mother is functional, the individuals are healthy. If the maternal copy is defective or deficient, the individual suffers from the Angelman syndrome..
