Answer:
Both have great effect on plant when increases from a certain limit.
Explanation:
When the temperature falls in the optimum range it has a good effect on plants growth because the rate of photosynthesis is maximum. Precipitation also has a great effect because it provides water that is necessary for the plants. If the temperature increases from a certain limit, it burns plant body and decreases photosynthesis whereas if precipitation increases it causes flood condition which kills the plant due to removal from the soil.
Answer: <u>Activators </u> can switch on enzyme activity, while <u>inhibitors </u>can switch off or reduce enzyme activity.
Enzymes are biomolecules that catalyzes a reaction. The enzymes can either speed up or slows down a reaction. Activators are compounds, molecules or elements that attach to the enzyme and promotes its activity. Inhibitors are factors which prevent the activity of the enzyme. Both activators and inhibitors are necessary for cellular metabolisms taking place in a living organism.
