Answer the following questionsa)How long will it take for a dolphin population to be reduced by 50% if the intrinsic rate of increase is -.04?b)In the last 70 years the blue whale population decreased from 340,280 to 4,727. What is the intrinsic rate of decrease (r)? c)If the current intrinsic rate of increase for blue whales is .1, how long will it take the current population of 4,727 to climb back to 340,280?

1.) Which statement below is not consistent with a population in Hardy-Weinberg equilibrium? A.) Genetic drift is occuring. B.) Random mating is occuring. C.) Population size is large. D.) Migration is not occuring. 2.) Sickel cell anemia is an autosomal recessive genetic disorder. Because individuals affected by sickle cell anemia have defective hemoglobin proteins, their blood cannot transport oxygen properly. There appears to be a relationship between the incidence of malaria and sickle cell anemia. Individuals with sickle cell anemia are carriers of the sickle cell allele have some resistance to malaria. Malaria is caused by the parasite Plasmodium and is transmitted between humans by mosquitoes.” If scientists are successful in significantly reducing or eliminating malaria, the best prediction for what will happen to the allele for sickel cell anemia in the population is that it will: A.)not be affected by the elimination by malaria. B.) increase as its selective advantage…
One reason why human populations have been able to sidestep the factors that usually control population growth is that: a. the carrying capacity for humans has remained constant sincehumans first evolved. b. agriculture and industrialization have increased the carryingcapacity for our species. c. the population growth rate (r) for the human population hasalways been small. d. the age structure of human populations has no impact on itspopulation growth. e. plagues have killed off large numbers of humans at certaintimes in the past.

1.In wildlife management, population numbers must be sustainable in that populations cannot exceed the environment’s ability to support them. Using the ∆N formula, consider the following: Coyotes are members of the Canis family, or dog family, that wanders natural or agricultural grasslands and temperate forest in search of rodents and small prey. Occasionally they will form packs to bring down a larger animal – perhaps a young, sick, or old deer. In this scenario, assume population numbers of coyotes have increased dramatically. a.Using your knowledge of the ∆N formula, provide four possible causes for this dramatic increase in population. b.Assume you are a wildlife manager and that the high coyote population is resulting in more human/coyote interactions. Steps need to be taken to correct the imbalance in coyotes. Provide two ecologically sound solutions to the problem.
