Sunlight is slowed most when traveling through a) water. b) a vacuum. c) the atmosphere. d) none of these, as light always travels at the same speed.

A

Explanation:

This is because water is the densest medium among the three. This means there are more molecules of the material per unit volume as compared to the other media. Therefore,  a ray of sunlight in water bombards with many molecules in its straight path as compared to in atmosphere or vacuum. This slows it down and diffusing it. This is why light does not get to great depths in oceans and some deep lakes leaving these deep layers of water, dark.    In vacuum, light can travel the farthest, followed by the atmosphere, then water.

answer: i cant find your answer. do u have another way i can answer it for you : )

explanation:

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.
