Match the following terms and definitions. 1. occurring in the presence of oxygen anaerobic 2. occurring in the absence of oxygen fermentation 3. utilization of food molecules and energy in life processes aerobic 4. an energy-sharing arrangement of atoms to each other as parts of a molecule chemical bond 5. the stage of respiration that occurs in anaerobic conditions—for example, yeast fermentation assimilation

Explanation:

A process of respiration which occurs in the presence of oxygen is known as an aerobic process.

Whereas a process of respiration which occurs in the absence of air is known as anaerobic respiration.

Assimilation is defined as the process in which an organism is able to utilize the food molecules and energy  in its process of life.

A chemical bond is defined as the bond formed due to exchange of electrons either by sharing or transfer. In this process energy also gets shared.

Fermentation is defined as an anaerobic process in which an organic food is converted into simpler compounds along with the production of chemical energy.

Therefore, given terms are matched as follows.

1. occurring in the presence of oxygen - aerobic

2. occurring in the absence of oxygen - anaerobic

3. utilization of food molecules and energy in life processes - assimilation

4. an energy-sharing arrangement of atoms to each other as parts of a molecule - chemical bond

5. the stage of respiration that occurs in anaerobic conditions—for example, yeast fermentation - fermentation

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
