Answer:
Photons
Explanation:
The retina is a thin layer (membrane) in the eye that receives light through photoreceptor cells that convert this light into chemical and nervous signals transported to the brain's visual center.
The photoreceptors in the retina are known as rods and cones. Rods detect motion and sare responsible for black and white vision, they are present in the macula. Cones on the other and, are responsible for central and color vision. <em>These photoreceptors absorb photons that trigger the membrane's potential of the cells.</em>

Answer:
sinoatrial node and atrioventricular node
Answer:
The correct answers are-
a. Its metabolic demands increase.
b. It's surface area-to-volume ratio decreases.
c. Its ability to transport enough nutrients in and transport wastes out to meet cellular metabolic demands decreases.
Explanation:
As the size of a cell increases the surface area to volume ratio decrease. So a big cell has less surface area and small volume. Therefore surface area for transfer of metabolic substance per unit volume decreases so the cell's ability to transport enough nutrients in and transport wastes out to meet cellular metabolic demands also decreases.
But due to an increase in the volume of the cell the metabolic demand of cell increases because a larger cell requires more nutrients than a smaller cell to survive which can not be fulfilled efficiently due to less surface-area-to-volume ratio.
Therefore the correct answer is a, b, and c.
The answer to this question would be leukopenia.
Leukopenia is a condition where the total white blood cells count is too low. White blood cell is fighting the microbes, so decreased of their number might cause the patient immune system to be decreased to, leading to immunocompromised status.
