The model for continuous-time exponential death is d𝑆(𝑡)d𝑡=−𝑐𝑆(𝑡)In this model, what is c?Group of answer choicesThe death rate per capitaThe change in the population size over timeThe population size at time tThe number of individuals who have died

The model for exponential growth coupled to exponential death is d𝑆(𝑡)d𝑡=𝑟𝑆(𝑡)−𝑐𝑆(𝑡). Which of the following statements about the value of r/c is CORRECT?Group of answer choicesIf it is smaller than one, the population size will increaseIf it is smaller than zero, the population size will decreaseIf it is greater than zero, the population size will decreaseIf it is greater than one, the population size will increase

At time 𝑡=0 years, the population of a certain city was 23,144. During each of the next 10 years, the population decreased by 4% per year. Based on this information, which of the following models the population as a function of time 𝑡, in years, for 0≤𝑡≤10 ?Responses23,144-0.04𝑡23,144 minus 0.04 t23,144-0.96𝑡23,144 minus 0.96 t23,1440.96𝑡23,144 open parentheses 0.96 close parentheses to the power of t

n the logistic model for resource-limited growth (and death) of a population, the growth rate per capita, r, is replaced by:𝑟(𝑆(𝑡))=𝑟𝑚𝑎𝑥1−𝑆(𝑡)𝐾.Which of the following statements about r is CORRECT?Group of answer choicesThe value of r cannot be larger than rmax.All of the other answers are correctThe value of r decreases with increasing population size S(t).The value of r is zero when the population size S(t) = K.

In what situation might a continuous-time exponential growth model be a GOOD description of how population size grows over time? Group of answer choicesA population of animals infested by transmissible deadly parasitesA population of birds with several predators.A bacterial culture growing in a laboratory with an unlimited amount of resources.A population of rats living on a small island.
