Because the cells in the body are in a state of starvation, how does the body compensate to maintain homeostasis

The plasma levels of fatty acids and ketone bodies increase in starvation, whereas that of glucose decreases. The metabolic changes on the first day of starvation are like those after an overnight fast. The low blood-sugar level leads to decreased secretion of insulin and increased secretion of glucagon.

Yes yes yes very good

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!
