<span>Aquatic organisms and the physical and chemical components of their environment are inseparably inter-related and interact with other. Flow and water chemistry are the primary factors governing life in riverine habitats, and both are closely related to seasonal variations.</span>
Answer:
The correct answer will be- the cell structures undergo repeated breakdown and formation.
Explanation:
The carbohydrates, fatty acids and amino acids are the three important bio-molecules which form the components of various cellular structures.
In the given question, the cell biologist radiolabeled these biomolecules and then observed the cellular structures after cell metabolism. He found that few cellular structures contained radiolabeled structures and few not. This showed that the cellular structures constantly undergo changes in their structures due to cellular metabolic reactions and are broken down and reformed.
Thus, the cell structures undergo repeated breakdown and formation is the correct answer.
