- Most sexually transmitted disease causing pathogens namely Syphilis, Trichomoniasis and HIV are examples of the density dependent transmission.
- Example of a pathogen with frequency dependent transmission is Myocobacterium tuberculosis (bacterial disease causing pathogen).
Explanation : The Sexually transmitted disease causing pathogen is a density dependent transmission because the per capita contact rate between the susceptible and infected individuals depends on the population density. Whereas the Myocbacterium tubeculosis causing disease is frequency dependent transmission as the per capita contact rate between the susceptible and infected individuals does not depend on the population density.
Give one example of a pathogen with density dependent transmission and one example of a pathogen...
Define the following terms and give one example of each. (4 marks) density-dependent factor: - example: density-independent factor: - example:
1) Explain in your own words how immune system evasion represents a trade-off for the pathogen. 2) Describe an evolutionary explanation for why the human adaptive immune system has evolved to "react" to the presence of pathogens, rather than always be prepared to recognize and fight off any possible pathogen.
Give an example of how density-dependent and density-independent factors might interact.
Give an example of a situation that shows a strong correlation and has one or more extraneous variables present. Explain how any of these variables could affect either the independent or dependent variable.
Define and give an example of dependent vs. independent samples, and indicate why, in two population testing it is critical for reliable hypothesis testing. Dependent: Independent: Why Critical?
Infectious diseases can emerge through genetic, social and behavioural changes in the host and/or pathogen. Provide: (a) two examples of genetic changes, and (b) two examples of social or behavioural changes that have enabled new infectious diseases or new strains to emerge. In all four examples that you give, name the pathogens and explain how the changes led to disease emergence. Mandatory word limit: Write no more than 200 words in total.
1. A. Give an example of dependent samples. B. Give an example of independent samples. C. When do you reject the null hypothesis? D. Why don't we enter a value into the hypothesis in statcrunch (why is it kept at zero)? E. What is the only type of 2 sample mean test do we do?

Define System-1 and System-2 thinking in your own words. Give an example from your personal or work life where you would use each of them, explaining why each is appropriate to the situation in which you use it. Heuristics Define "heuristic" in your own words. Give an example of a heuristic might be used in your personal or professional life and briefly show how it could have a positive or negative effect. Do not use examples found in the text....
