sleep periods in which a person's eyes move rapidly

Explanation:

In REM (Rapid eye movement stage of sleep) a sleeping person has a conscious mind due to which he/she is able to sense his/her dream to be taking place in reality. The brain of a person in this sleep stage is as active as the brain of an awake person.

Due to this conscious dreaming, a person eyes move very fast which is also known as darting of eyes.

Thus, REM sleep refers to sleep periods in which a person's eyes move rapidly

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
