Answer:
a) polar heads on the outside and nonpolar fatty acids on the inside
Explanation:
The cell membrane is made up of phospholipids arranged in a bilayer, where hydrophilic polar (negatively-charged) heads of phospholipids interact with water molecules (i.e., aqueous surrounding media). Moreover, non-polar (uncharged) fatty acid tails are hydrophobic because they cannot be dissolved in water. Thus, the bilayer cell membrane is a structure where non-polar fatty acid chains are localized in the inner region (away from the water), while hydrophilic phosphate heads face outward, interacting with water on both sides of the cell membrane.
Answer:
to provide electrical signals to initiate peristalsis
Answer:
E. The man had one dominant and one recessive allele.

Woman marries a man with Wilson disease, a autosomal recessive disorder. The woman doesn't have the disease, the son got it. Therefore, the man has another dominant allele.
Diffusion helps maintain homeostasis so the cell doesn't have doesn't have a build up of waste chemicals. diffusion transports some of the waste to the outside of the cell so the amount of waste doesn't become to high and dangerous.
