Explain the orientation of the phospholipids.

phospholipid molecules organize themselves into a bilayer where the hydrophilic heads are facing towards the water, whereas the hydrophobic tails are avoiding the water.

Explanation:

Phospholipids consist of a hydrophilic head and a hydrophobic tail. These two components create a cell's double membrane.

In the phospholipid bilayer, the heads of the phospholipids are found at the surface of the intracellular membrane and extracellular, while the tails are found in between each of the heads. The phospholipids are very closely packed, with the heads more or less touching, and the tails found attached.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
