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 iris is composed of muscle layers - an outer layer of longitudinal smooth muscle and an inner layer of circular smooth muscle. The inner circular layer is innervated by the parasympathetic nerves. When these muscles contract, they that cause the pupil to constrict in bright light. the The outer layer of longitudinal smooth muscle is innervated by the sympathetic nerves. When these muscles contract, they that cause the pupil to dilate in dim light.
