Please help Which sentence supports the fact that we always see the same side of the Moon?
The Moon takes about four weeks to rotate once on its axis and about the same time to orbit the Earth. The gravitational effect of Earth has slowed the rotational period of the Moon to match its orbit. Since the rotational period is exactly the same as the orbital period, the same portion of the Moon always faces Earth. As the Moon orbits Earth, the lit side that we see changes in size. These changes are called the lunar phases.

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.
