B. PACs allow their members to support a range of candidates with a single contribution.
C. Candidates receive contributions from so many PACs that the effect of any single PAC is diluted.

Cellular Respiration
Carbon stored in plants reaches the atmosphere through the process called cellular respiration.
Cellular respiration in Plant can be defined as a set of metabolic activities that enables plants to transform energy from nutrients into ATP (adenosine triphosphate) with the use of CO2 and H2O to release waste products such as carbon and oxygen.
Carbon and oxygen are waste products and are discharged into the environment through the pores underneath the leaf of a plant.
