Given the following steps for a mechanism: Step 1: O3 + NO = NO2 + O2 (slow)
Step 2: NO2 + O = NO + O2(fast)

Define mechanism.

Explanation:

Prokaryotes have the advantages associated with greater simplicity, including more rapid reproduction, rapid mutation and adaptation to new environments, and more diverse metabolic systems. They also possess an ability to pass on adaptive genes to other bacteria in the form of plasmids.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
