15. Sarah is a biologist who is studying a species of crab. In the wild, crabs with larger pincers will have greater reproductive success than those with smaller pincers. To
investigate this further, she placed 50 crabs with small pincers and 50 crabs with large
pincers together in an isolated area that closely resembled their natural environment.
She observed several generations of the crabs over the next ten years. If her
experimental setup replicates the natural selection process in the wild, which result is
most likely to be observed?
A. the crabs born with small claws would develop larger claws and pass this trait to their offspring
B. The percentage of crab as with large claws would increase.
C. The percentage of crabs with small claws would increase.
D. the DNA in crabs with small claws would mutate in order to produce larger claws.

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
