Biologists have observed similarities across the domains of life in the strategies that organisms have evolved to solve common problems. Organisms that are otherwise very dissimilar can have similar mechanisms for responding to information from their environments. Several examples are listed below. For each example, 1) describe the behavior that the two organisms have in common, 2) explain how this behavior helps each organism survive, and 3) predict a third organism that would be likely to also share this behavior and explain why. a) Responses to seasonal changes by whales and by birds (5 points)

b) Chemical signaling between ants and between slime molds (5 points)

c) Attraction to flowers by birds and by bees (5 points)

d) Dormancy behavior in perennial plants and in hibernating bears (5 points)
