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
Answer:
the glutamate causes an influx of ca2+ions the nerve cell akin to what occurs during depolarization.
That answer sounds great! You might also want to add that the cell cycle is thrown out of control by the mutations that occur. Cancer is fundamentally the accumulation of reproduced mutated cells.
