Hello can u help me with these 3 questions.....

Exercise 1. What is a Minimal Viable Population? Why are Zoos and Animal Conservationists concerned with this for tigers or snow leopards? Name four other species and their population problems/solutions. Cite your references.

Exercise 2. Evaluate the human population growth rates for FOUR different COUNTIES in YOUR STATE. Evaluate the population trends in each county (not country). Why are they different or the same? Expound on your reasons. List your sources.

Exercise 3. Rotary International is an organization that has many goals, one of which was/is to eliminate polio from the world's human population. Give a brief history of this mission (one paragraph) and then give YOUR prediction about the world's population's growth if another condition/disease (you choose it) is eliminated from the human population worldwide. Include a population curve for the population WITH the condition and then a simultaneous curve on the same graph of the population WITHOUT the condition after 100 years. (Color code your two population curves.) Cut/paste the graph into the msword document for this week's iLab. Include the sources of the original population density's data.

Will need them by wednesday....
Thank you
