By regulating the cell cycle, multicellular organisms gain which of these benefits? A. eliminating unnecessary genes B. healing wounds effectively C. replacing lost cells such as shed skin cells D. preventing communication among cells All of the above B & C only A & D only Other:

## Step 1<br />The cell cycle is a series of events that cells undergo as they divide and grow. It is a fundamental process in all living organisms, including multicellular organisms. The cell cycle is regulated to ensure that cells divide in a controlled manner, which is essential for the growth and development of the organism.<br /><br />## Step 2<br />Option A, "eliminating unnecessary genes", is not a direct benefit of regulating the cell cycle. The cell cycle is about cell division, not gene regulation. Therefore, this option is not correct.<br /><br />## Step 3<br />Option B, "healing wounds effectively", is a benefit of regulating the cell cycle. When an organism is injured, the cell cycle is regulated to produce new cells that can replace the damaged ones. This is how wounds heal. Therefore, this option is correct.<br /><br />## Step 4<br />Option C, "replacing lost cells such as shed skin cells", is also a benefit of regulating the cell cycle. The cell cycle is regulated to produce new cells that can replace the ones that are naturally shed or lost. This is how the skin, for example, is constantly renewed. Therefore, this option is correct.<br /><br />## Step 5<br />Option D, "preventing communication among cells", is not a benefit of regulating the cell cycle. In fact, communication among cells is essential for the coordination of cell division and other cellular processes. Therefore, this option is not correct.
