- A study of smoking and lung cancer was conducted in a small island population. There were a total of 1,000 people in the study, and the study participants were followed over a ten year period. Four hundred were smokers and 600 were not. Of the smokers, fifty developed lung cancer. Of the non-smokers, 10 developed lung cancer. Calculate the relevant measure of association, interpret and make a conclusion. Compute Attributable Risk and interpret . Describe the difference between incidence rate and the prevalence rate.The fundamental axiom of preventive medicine suggests that: Select one: a. We should screen the population to identify those with only slightly abnormal values (e.g. blood pressure) and then treat those individuals preventatively. O O b. We should screen the population to identify those with highly abnormal values (e.g. blood pressure) and then treat only those individuals. C. We should screen the population to identify those with only slightly abnormal values (e.g. blood pressure) and then only treat those individuals who show symptoms of disease. d. We should not screen the population and identify those with highly abnormal values (e.g. blood pressure) as they become sick and then treat only those individuals.The lenz-ising model has veen linked to: I.

- 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 school The proportion of DDT-resistant mosquitoes in a population remains constant due to 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 introduced to a rainforest. Over the next year, the finches showa death rate of…3. Researchers are investigating a newly discovered condition that greatly increases the likelihood of lung damage associated with the use of e-cigarettes. They found that 2% of their study population has the condition. The researchers believe they have found a useful marker locus for assessing the presence of the condition in individuals with unknown family history. They have found that, of those individuals with the condition, 99% have the marker allele M1. Of those without the condition, 99.8% have an alternative allele M2 at the marker locus. What is the probability that an individual has the condition if they have marker allele M1 and what do you conclude about the utility of the marker locus for indirect diagnosis?7. Red blood cells can possess a surface antigen called the Rhesus (Rh) factor. Rh+ (presence of the factor) is dominant over Rh¯ (absence). A village of population 400 was sampled and the frequency of the allele coding for Rht was found to be 0.356. a) Determine the number of individuals in the village who will be Rh b) Determine the probability of being heterozygous
