Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
They are accepted as true until they are proven false. Once a theory has been tested and it is wrong, then it is no longer true.
Answer;
-Skin cells do not need crystallin for their function.
-Skin cells have the crystallin gene but do not express it.
Explanation;
-The crystallin proteins are water-soluble structural proteins that occur in high concentration in the cytoplasm of eye lens fibre cells. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors.
-The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. The skin cell does not make crystallin protein because the skin cells do not need crystallin for their function and also they have the crystallin gene but do not express it.
Answer:
Symptomatology and transmission
The clinical manifestations of acute HBV infection are age dependent. Infants, young children (younger than 10 years of age), and immunosuppressed adults with newly acquired HBV infection are usually asymptomatic. [2] Older children and adults are symptomatic in 30%–50% of infections
