All right, so you are starting a population of wild coyotes and notice that every three years there's an epidemic of bacterial disease, which is the following is most likely an explanation for this periodic cycling of the disease.
00:10
Either new coyotes, which are susceptible to the disease, are continuously born in the population, coyotes are dying from other causes over time.
00:18
During an outbreak, the proportion of coyotes who are infected slowly falls as they recover, or coyotes from other populations who have already been infected and have come from the disease immigrate into the study population.
00:30
So taking these just at face value right now, i would say the best answer probably here would be a, which is this here.
00:44
New coyotes, which are susceptible to the disease, are continuously born into the population.
00:50
And this is going off a little bit of outside knowledge as well.
00:53
So coyotes become sexually mature in one year and live an average of six to eight years in the wild.
01:02
So if the infection spreads through the population, then resistant animals would live, survive, and may have offspring...
