In sea urchins, the protein bindin enables sperm to attach to eggs, and is thought to play an important role in successful fertilization in the ocean. Bindin genes differ substantially among sea urchin species. The bindin gene is therefore likely to play a major role in: a. Geographic separation
b. Prezygotic isolation
c. Postzygotic isolation
d. Gametic isolation
e. Both B & D

b. heterotroph

explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
