The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.
Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.

The hearts contraction that maintains our blood pressure allowing us to breathe and exchange gases at all levels of respiration, ensuring oxygen is provided to all cells of the body, and waste products are eliminated.
Answer:
Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus
Explanation:
Proteins are mainly made up of amino acids. The basic structure of amino acids is that they have a carboxylic group, amino group and side chain. The carboxylic group is mainly Carbon, Hydrogen and Oxygen. The amino group is mainly Nitrogen and Hydrogen. The side chains are unique per amino acid having different elements including Phosphorus.
