Pls the phospholipid bilayer of the cell membrane is both hydrophobic and hydrophilic. why is this important to the function of the membrane? a. to maintain balance of water and nutrients in the cell. b. to allow cellular bonding. c. to allow for covalent bonding.

The cell membrane separates the intracellular environment from the extracellular environment outside of the cell. A phospholipid is composed of a phosphate group and a lipid. It is composed of a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails.

The structure of the bilayer is such that the tails are shielded from contact with water, creating a selectively-permeable barrier which will be impermeable to most hydrophilic molecules.

So, the answer is A) To maintain balance of water and nutrients in the cell.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
