Juli2301 [7.4K]

Answer:

The answer is C.

Explanation:

The initial proportion of 90% light-brown (sand-like) colored fish to 10% mottled fish is the result of the light-brown fish mixing with their background and thus being preyed less by the birds than the mottled fish which are of course more visible above a light brown sandy bottom. The higher predation results in the removal of more mottled fish and thus a smaller number of these fish in the population. When the gravel is added to the bottom of the lake, this situation reverses. Suddenly the light brown fish are more visible to the birds and we can expect that their numbers will decrease, while the mottled fish will become more numerous as they will be harder to spot and capture by the birds, and will therefore survive more than their pale counterparts.

What is one way that changes can occur in a DNA sequence?
zaharov [31]
<span>A change in a DNA sequence is called a mutation. Mutation occurs through a large variety of processes. The most written about in the press is of course the chemical-induced mutations. There is a large variety of chemicals that can induce mutations, most of time by binding to the DNA itself and breaking it, forcing an imperfect reparation or by blocking the replication of the DNA, which will force the replication system to duplicate it imperfectly, i really hope this helps, good luck babe!!</span>
