During the warm temperatures of summer, the arctic fox produces enzymes that cause its fur to become reddish-brown. During the c

old temperatures of winter, these enzymes do not function. As a result, the fox has a white coat that blends into the snowy background. What explains this change in color?
the genes of a fox are made of unstable DNA
mutations can be caused by temperature extremes
random alteration of DNA can occur on certain chromosomes
the expression of certain genes is affected by temperature

Answer: the expression of certain genes is affected by temperature

Explanation:

For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.

For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.

Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature

"Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA
Dima020 [189]

Answer:

G - 21%

T - 29%

A - 29%

Explanation:

Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.

From the information given, C is 21%

Therefore G is also 21% of the genome as  C is bound to G, the therefore are the same proportion.

C and G make up 42% of the genome (that 21% + 21%).

The remaining 58% (100%-42%) is made up of A + T

Similarly the proportion of A is equal to that of T,

Hence A is 29% (half of 58%) and T is 29%.
