Explanation:
Production. According to the U.S. Energy Information Administration, most of the nation's electricity was generated by natural gas, coal, and nuclear energy in 2018. Electricity is also produced from renewable sources such as hydropower, biomass, wind, geothermal, and solar power.
If the temperature is too low, enzyme molecules don’t have enough kinetic energy to collide and combine with other substrate molecules. So the enzyme activity/ reaction rate will be very low. The rate will rise again once the temperature increases to its optimum temperature.
But if the temperature is too high, enzyme will be denatured, which means the shape of the active site of the enzyme is changed. It can no long combine with other substrate molecules. The rate will drop significantly. Yet, lowering the temperature won’t help because denaturation is permanent and irreversible.

Answer:
The answer is C. cytoplasmic proteins of bacteria
Explanation:
The immune system includes innate immune responses and adaptive immune responses.
- Innate immunity: rapidly act against strange toxin or invaded microbes. It evolves membrane bound receptors and cytoplasmic proteins that present on the surfaces of invading microorganisms.
- Adaptive immunity: it expresses exquisite specificity for target antigens.
