Answer:
a. hemoglobin in red blood cells
Explanation:
Carbon dioxide is constantly produced by cells during cellular metabolism (cellular respiration), generating a concentration difference between the interior of the cell and its exterior (intercellular or interstitial space), and a consequent diffusion of this carbon dioxide into the interstitial fluid. Interstitial fluid now has a higher concentration of carbon dioxide than blood plasma, which causes a diffusion into the capillary. Carbon dioxide is carried by hemoglobin or dissolved in plasma.

the ability of the muscles to exert a force. The maximum amount of force that a muscle can generate in a single effort. </span>Muscular strength<span> in the upper body is tested by the maximum bench press and the lower body by the maximum leg press</span>
Answer: Option D.
Explanation:
Active transport is defined as the transfer of molecules and other substances across a membrane from lower to higher concentration against the concentration gradient. Active transport utilizes Adenosine Triphosphate (ATP) as a energy source for the continuous movement of molecule against its concentration gradient.
Active transport function continuously because constant process of diffusion allows the movement of solutes in other direction.
For example cells are having higher concentrations of potassium (K+) and lower concentrations of sodium (Na+) in comparison to extracellular fluid. concentration gradient supports diffusion of Na+ ion into the cells and diffusion of K+ out of the cell. In such manner other small substances like glucose and amino acid constantly move across the plasma membranes and maintains concentrations of ions and other substances required for the body.
Hence, the correct option D.
