- Which of the following is the best definition of the term controlled variables? a) The variable is what is measured or recorded in the experiment. This is the variable in an experiment that the researcher can change and b) control A treatment level that is often used for comparison, it is usually zero or a c) natural level. d) The things in an experiment that are kept the SAME for every level of treatment. e) A statement explaining an observation.The following is an example of what kind of study? Participants are recruited based on exposure status as ascertained through historical records (medical records or other records from the past), disease status is determined after recruitment, and risk of disease among the exposed is then compared with risk in the unexposed. a) Ecological study b) cross-sectional study c) case control study d) cohort study e) randomized control trialThe SIR model for the spread of an infectious disease is used to predict the spread of a disease in a community. The variables are: S: Number of susceptible people, who are currently healthy but could get the disease I: Number f=of infected people Put S horizontally and I vertically. They are related by the following equations. S'=-0.0005SI I'=0.0005SI-0.05I What are the S-nullclines and the I-nullclines?

Note: Provide an answer with 150-200 wordsIn the early part of this century, tropical medicine expert Dr. Richard P. Strong obtained permission from the Governor-General of the Philippines to inoculate a number of criminals with plague bacillus. The Filipino prisoners were not asked for their consent, but they were rewarded by being provided with cigars and cigarettes (Pahl:284). Discuss the ethics of this experiment. Discuss the moral issue of informed consent. Why is it so important in medical research and experimentations? What are some of the circumstances that make it difficult to obtain? Why is there a need for human experimentation?https://www.nature.com/articles/s41598-020-75261-9 Identify the population group that will benefit from this research.
- A population with three life-stages separated by 3 years is modelled by a Leslie matrix, resulting in these predictions. The x-axis shows the number of time steps in the vector dynamics from the Leslie matrix multiplication. How many years before the long-term dynamics take over? a) 0 b) 2 c) 5 d) 15 What is the long term prediction for this population? a) decreases to zero b) anything could happen c) increases to infinity d) stable If the population started with many more animals and in different proportions from each life stage, would the prediction be the same or different? If the population started with many more animals and in different proportions from each life stage, in the long term dynamics what would be the ratio of newborns (stage 1) to youths (stage 2) to adults (stage 3). a) about 1 to 1 to 1 b) about 4 to 2 to 1 c) about 6 to 3 to 1 d) no way to judgeThe 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.Which of the following is NOT an important step in developing a research hypothesis?
