b. Alleles
c. Polygenic
d. Chromosomes
Question 2

B) The tails are in contact with extracellular and intracellular fluid and the heads oriented away from these fluids
C) Half of all heads and tails are in contact with extracellular fluid
D) Both heads and tails are in contact with intracellular fluid
