D! Predictable and controlled
Answer;
-The rate of the reaction;
The presence of an enzyme affects only the rate of the reaction.
Explanation;
-Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
-Additionally, the rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.
Answer:
changing environment
Explanation:
If the species fails to adapt, it will die off.
