Asingle pair of goldfish in a aquarium produced a large number of offspring.

these offspring showed variations in body shape and coloration.

the most likely explanation for these variations is what?

(a.) offspring were adapting to different environments.

(b.) parent fish had not been exposed to mutagenic agents.

(c.) offspring were produced from different combinations of genes.

C. Offspring were produced from different combinations of genes.

Explanation:

The offspring would not be adapting to different environments as they all live in the same aquarium. There is no mention of mutagenic agents present in the aquarium and that would have had more of an effect on the parents and not the offspring. The parents may have had different sets of alleles which could produce a variety of phenotypes of their offspring.

this protocol provides a detailed procedure for chromatin immunoprecipitation (chip) to study the dna-protein interactions.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
