    Which of the following is a possible scenario that could lead to a new species? Select one: a. A tree frog needs to jump higher to escape predators. The frog's offspring jump higher due to the frequency of jumping by the parent. b. Over time, many mutations occur in the gene pool of a population of butterflies. c. A giraffe stretches its neck to reach the leaves at the top of the tree. The offspring are born with necks that are longer than the parents due to the stretching. d. A bird and a frog reproduce with one another, creating a "brog."

    It isn't A because a frog teaching its offspring is not going to change the species. It isn't C because stretching it's neck will not make it's offspring have longer necks. And it isn't D because a bird and a frog will not mate.

    An earthquake causes a one hundred mile square area to be fractured into four different geographical areas. Two of the areas have a river running through it, the other two have ponds. Which of the following is a likely scenario based on the new geography? Select one: a. Over time, the areas with the rivers will have less animals than the areas with the ponds. b. Within a couple years, the areas with the river will have many more plants than the areas with the ponds. Incorrect c. Animals that need access to large quantities of salt water will be found in the area with the ponds. d. Flying animals will be able to cross back and forth between the two areas easily.

Evolve to have less hair over the course of a few years b. Become extinct if the temperature gets too high c. Become the predominant form of life d. Have more offspring in order to increase its survival rate Incorrect
