Avariegated leaf has white patches. the patches occur where chlorophyll is missing from the chloroplasts in some of the cells. chloroplasts have their own dna, and are inherited from one parent only. how is the variegated leaf trait inherited? a. variegation is inherited from the male parent. the nucleus of the male gamete transforms into a chloroplast. b. variegation is inherited from the female parent. only the egg cell contributes cytoplasm with chloroplasts to the embryo. c. variegation is inherited as a codominant trait, causing white and green leaf patches. d. variegation is inherited from the male parent. the male gamete contributes cytoplasm containing chloroplasts to the embryo.

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.

As a result of these processes the single celled organism accomplishes
