The answer is I guess A. Omnivore. That is the only answer choice you gave.
Answer:
- <u>A increases the rate of chemical change.</u>
Explanation:
Elements undergo chemical bonding-where electrons are shared, and rearranged to form various molecules and compounds. Bond formation in chemical reactions have specific requirements for molecular configurations and energy.
Molecules usually collide at random til conditions are favorable for bonding. Chemical change or reactions occur at faster rates at higher temperatures. Heating molecules increases their collision frequency and makes it more possible for the correct molecular orientation (for breaking and forming bonds) and energy to react are present.
