Alarge island has many different types of geography, including a large mountain range in the center. the island is broken into a chain of many small islands when the ocean level rises. after the small islands form, the rate of speciation is very high.

3 reasons that this area has a high rate of speciation and explain each one in a sentence.

Which process of living things produces water that enters the water cycle

How water is moving through the ecosystem ?

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.
