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
I think it is B. biome

<span>Forces can be measured using a device called force meter. The unit of force is called the Newton. It is represented by the symbol N. A force of 2N is smaller than 7N. A force usually results from an interaction.</span>
Some are:
-laws tell how
- laws are proven true
- Theories attempt to explain
- Theories are developed based on likely true things, but not necessarily proven
- hypothesis is an educated guess
- hypothesis is made before your test/experiment.
- laws are formed after tests and experiements.
- Theories are often based off of tests/experiment, but again, not necessarily proven to be true.
