True is the answer hope this helped
The body cells depend upon products of both the respiratory and digestive systems' functions in order to maintain themselves. To produce energy, cells burn nutrient molecule fuel in oxygen. The digestive tract provides the nutrient molecules, through the process of digestion, while the respiratory tract provides oxygen. As such, the two systems work together to give your cells the ingredients they need to produce energy, which they use to communicate, build cellular products and grow.
Answer/explanation:
These cells are diverse since they utilize the same set of qualities in an unexpected way. So indeed in spite of the fact that each of our cells has the same 20,000 or so qualities, each cell can select which ones it needs to "turn on" and which ones it needs to keep "turned off".
