During the process of cellular respiration, the cells use oxygen and give up carbon dioxide as their by product.
Some plants also take in oxygen and release carbon dioxide during the process of cellular respiration. The cellular respiration in the plant is similar to the cellular respiration, which occur in animals.
Hence, the given blank can be filled with cellular respiration.
Contain a repair mechanism inherent in their biochemistry (repair enzymes)
Explanation:
When cells are exposed to sublethal doses of ionizing radiation, repair and recovery may occur because cells: Contain a repair mechanism inherent in their biochemistry (repair enzymes).
The answer to this would be D: physical components of the environment, such as rocks and sand. The word "biotic" mean all the living organisms within an ecosystem such as plants and animals.
