Tortoises found on the Galapagos Islands can have varied phenotypes. One of the variations in the phenotypes is with regard to their shells. They can have a domed shell with a hood above the head. The shells without domes lack the hood above the head, such that the tortoise's neck is always pointing downward. A group of evolutionary biologists studied the tortoise population for generations on these islands. The study coincided with a severe drought in the area that lasted many years. The data for the changes in tortoise shell shape is shown here. Evaluate the data and select the statement that is best supported by this data. B

one would be wind another would be water density

the answer is a) a shiprock was formed by igneous process

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
