A Hippogriff is a magical beast that had tail of a horse. It is very similar to another magical creature, the Griffin, with the horse rear replacing the lion rear. A slightly different breed of Hippogriffs, living in the Rathlin Island—the northernmost point in Northern Ireland, was known to have a growth rate of 0.2 individuals per individual—year. From an initial population of N0, it grew to 35 individuals after 5 years. After 17 more years, the total population of hippogriffs in Rathlin Island rose to 1588 individuals. Solve for the carrying capacity of Rathlin Island and the initial population of the said specie.
Assume that the population of the greater roadrunner in the Guadelope Desert was 250 per hectare at the beginning of 1999. If the carrying capacity, K , is 750 and r=0.25 per year, what is the number of roadrunners: (d) a century later, and (e) a millennium later?

- A certain strain of bacteria will divide itself from 1 to 2 every to [minute]. As a result, its population can be modeled as N (t) = No2. ---(eq 1) N(t) is the population at time t, NO is the population at the beginning = 100, t = time you wait [minute]. You prepare 6 dishes. Each dish contains 100 living bacteria at the beginning. Then you wait for 20 mins, freeze the first dish to stop the bacteria in the dish from growing. Then wait for another 20 mins, freeze the second dish (i.e. the total growth time for the second dish is 40 min). Proceed to the next dish in the similar process until all 6 dishes are done. After counting all the dish, you collect the data between time and population as follow: t(min) N(t) 20 132 220 40 60 311 80 369 100 622 120 836 Find to (the time for bacteria to divide itself).

Richard Dawkins first hypothesized the existence of the "greenbeard" allele to explain why we observe some unusual phenotypes, such as green beard. According to the hypothesis, the reason why the greenbeard phenotype is selected for is because the greenbeard individuals would preferentially receive altruistic benefit from non-greenbeard individuals. The reason why the "greenbeard" hypothesis is possible is because when direct fitness and indirect fitness are in conflict, it is always the factors that increase the direct fitness that will triumph over the factors increasing the indirect fitness. The "greenbeard" effect shows that it is possible to evolve altruistic behavior toward individuals who are not genetic kin.arrow_forward
