Which is NOT required for reciprocity (reciprocal altruism) to evolve?

  We examined these three graphs when discussing barnacle population dynamics. Visually, dN/dt is shown by… 

Regulating mechanisms influence the population growth rate. Some regulating mechanisms are density dependent, while others are density independent. Recall the population of barnacles that we discussed in class, shown below. Describe one density dependent and one density independent factor that may affect barnacle population dynamics and explain your reasoning. Advice: Make sure it’s clear which factor is which and that you understand why the factor is density dependent or density independent.

Select the correct option about the statement below. Iteroparous organisms may have a higher chance of some of their offspring reaching adulthood because they reproduce several times throughout their lives and some of those reproductive events may occur at times with favorable environmental conditions. Iteroparous organisms are often unable to put all of their energy into each reproductive event because they need to save energy for future reproduction.

Match the examples to the corresponding scale of ecology.

True or false: One way that altruism is maintained through natural selection is because it prevents a population from going extinct.
