Answer:</h3>
Enzymes functions in a specific temperature range.
<h3>
Explanation:</h3>
- Enzymes are biochemical catalysts whose function is to speed up the rate at which chemical reactions occur.
- Enzymes work best at a specific range of temperatures known as optimum temperature.
- Low temperatures below optimum levels deactivate the enzyme and thus lowering the rate of enzyme activity.
- Extreme temperatures, on the other hand, denatures the enzyme altering enzyme's active sites making it difficult for substrates to fit.
Genetic drift I believe because it means <span>variation in the relative frequency of different genotypes in a
small population, owing to the chance disappearance of particular genes
