The outside of the phospholipid membrane is hydrophilic which attracts water and the inner lipid layer is hydrophobic which repels water causing water to be pulled into or out of the cell based on the concentration gradient of solutes
If a heterozygous male with the genotype Ww is mated with a homozygous recessive female with the genotype ww, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are Ww, Ww, ww, and ww.
<h3>What is Genotype?</h3>
A genotype may be defined as the ultimate combination of the alleles of those genes which are selected for specific studies.
If a heterozygous male with the genotype Ww is mated with a homozygous dominant female with the genotype WW, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are WW, WW, Ww, and Ww.
Therefore, it is well described above.

Answer:
b. adrenal medulla
Explanation:
The gland responsible for the "fight or flight" response is the adrenal medulla. The nervous system sends out an impulse to smooth muscles and glands that tell the adrenal medulla to release adrenaline and noradrenaline into the bloodstream.
