Please help asap!! Imagine a population of birds in which first-year birds can either (1) find a mate and raise an average of three offspring or (2) stay in their parents' territory and help the parents raise two more offspring than the parents would have been able to raise without any help. Which of following statements best describes this situation? A) Most first-year birds would choose to forego breeding, increasing fitness.
B) The behavior of helping at the nest would not increase fitness in this population.
C) Altruistic behavior would be common in this population, increasing fitness.
D) Most territories would have young birds helping at the nest to increase fitness.

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
