Eye color is and example of a. Translation control
b. Gene expression
c. Transcriptional control
d. Gene regulation

b. Gene expression

Explanation:

The eye color trait is controlled by polygenetic heritability. A group of genes is responsible for the trait manifestation, and they must be associated to transmit the characteristic.

Eye color in a person is produced by pigments in the iris´ cells called melanocytes. At least two or more genes control melanin synthesis in the iris. Melanosomes are cellular structures produced by melanocytes, where melanin is produced and stored. Different genes control the eye color by its expression. We can name two of them as examples. There is a gene called OCA2 that codifies for the P protein synthesis. This protein plays an important role in the amount of melanin produced. The less P protein, the less melanin the cell will produce, which leads to blue eyes.  Another gene called HERC2 contains a region known as intron 86 that controls the OCA2 gene, by allowing or inhibiting its expression.

the answer is cell division : )

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
