Hamish is studying what happens when he sends a sound wave through different mediums, and he records his data in a table. A 2-column table with 4 rows titled Hamish's Waves. The first column labeled Wave has entries 1, 2, 3, 4. The second column labeled Information has entries liquid, solid, gas, liquid. Which statement could made about the data collected in Hamish’s table? Wave 1 will move the fastest. Wave 2 will move the slowest. Wave 3 will move the slowest. Wave 4 will move the fastest.

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.

Stem cells found adult tissue such as in bone marrow brain muscle skin and liver are only capable of what
