Answer: a biome is defined by its biogeography, temperature, and precipitation
Explanation:
Regulatory system. hope I helped !
he number of protons give elements their unique chemical properties, and define their electron energy levels. All three of these elements are naturally occurring, and act chemically like hydrogen because they each have one proton. The different number of neutrons gives them all greatly different atomic mass.

<span>You did not specific if the evolution of O2 gas comes from the decomposition of hydrogen peroxide. But I assume it is , since MnO2 is commonly used to increase the rate of hydrogen peroxide decomposition to water and oxygen.
Thus MnO2 increases the rate of O2 gas evolution, but the amount of O2 gas evoluted is the same. It does so by providing an alternative reaction pathway via a transition state with lower activiation energy.</span>
