ANOTHER 50 POINTS TO HELP ME Using information from data in Graph 2, describe the relationship between marine iguana body length and reproductive success for male iguanas on Genovesa and Santa Fe.

Describe the correlation (positive, negative or no relationship) for the data shown for one of the islands.

Explain how the relationship described in Part A would likely lead to natural selection over many generations of iguanas and identify the likely outcome for the body length trait in males of this population.

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.
