Question 15

which of the following is nonpolar and would not dissolve in water?

a)vitamin c

b)electrolytes

c)salt

d)vitamin a

Vitamin A

Explanation:

Vitamin A is fat- soluble and therefore would not dissolve in water.

D) Vitamin A is nonpolar and would not dissolve in water.

A nonpolar atom has no partition of charge, so no positive or negative shafts are shaped. The electrical charges of nonpolar atoms are uniformly circulated over the particle. Nonpolar atoms show high solubility in nonpolar solvents and not in water.

Among the substances given in the options, vitamin A is considered as best option because it is a fat soluble vitamin. On the other hand, other substance such as salt, Vitamin C and electrolytes are polar substance and shows high solubility in water.

answer///multiple alleles;

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.
