There is a theoretical protein called largeX that helps to stimulate growth of the body during adolescence. The promoter on the lrgX gene that codes for it normally can have a protein bind to it that promotes transcription called Largene. Largene, bound to the promoter, can receive yet another signal in the form of largeXase—a protein that changes the conformation of largene so that it can no longer bind to the promoter. Predict what would happen to an individual if he or she began expressing a lower level of largene than normal at puberty. The individual would show

a. degradation of lrgX
b. a smaller phenotype than others
c. an abnormally large height
d. an alternative form of largeX

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.

Which environmental change would most likely result in bullfrog offspring that are able to store more water than bullfrogs in previous generations?
