Question 1 A large outbred population would generally be more resistant to a novel pathogen than a small and inbred population because in the large outbred population: A greater proportion of individuals will be heterozyote at genes that mediate resistance There is likely more diversity among genes that code for the major histocompatibility complex There is likely more diversity among genes that code for Toll-like receptors There will be a greater number of alleles at genes that mediate resistance All of the above are true

- Measles is caused by an extremely infectious virus. Use the herd immunity equation to calculate the proportion of the population that needs to be immune in order to effectively halt the spread of measles via herd immunity. The Ro of the measles virus is 18 and the vaccine is 97% effective. Enter your answer as a decimal, not as a percentage. Round to the nearest 4 decimal places (example: 0.3568). It is recommended you do not round between calculation steps.What is the percentage of people that get Wolf Hirschhorn disease. Does it affect a particular gender/culture/age group. Is it preventable? If so give me some facts like. By doing this you can drop your risk by _____percent. This can lead to increase risk. If it is genetic then talk about how common it is in the populationIf these estimates are accurate and, for the sake of argument, let's say that the omicron variant has an Ro (R naught) of 4, what is - the minimum percentage of the population that will need to be immunized (or have immunity from catching the disease) to achieve herd immunity? 100- -Coverage Herd immunity Previously reported R, range 80- 60- 40- 20- '7'8'9'10' 11'12' 13' 14' 15 ' 16' 17 ' 18' 19' 20 Basic reproduction number (R) 50 75 35 85 105 (s) abesanos uogesunuu

- Suppose Inverness was considering offering a special add-on to its standard Dental insurance. For an additional 1 dollar a month a family could be fully covered for professional teeth whitening, something that normally would cost five thousand dollars a treatment. The whitening procedure would erase any stains that build up over time as a result of drinking too much coffee. Would this benefit create an adverse selection and/or moral hazard problem? If so explain why, and how the benefit could be better designed to address these issues.The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes?* nd 2 chool The proportion of DDT-resistant mosquitoes in a population remains constant due to O the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is intróduced to a rainforest. Over the next year, the finches show a death rate of…I am studying a species of octopus and find that some individuals have more resistance (immunity) to a common skin disease than others. I hypothesize that immunity will trades off with investments in other major life history traits. I predict that if I sample skin cells from different octopi in the wild, and assay them for immunity, females with higher immunity will produce fewer eggs. Which of the figures below would be the best choice for showing my prediction? A A B B
