A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
<span>(I got this from my handbook dictionary)
"the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes."
What that basically means is that homeostasis is the ability to respond to certain environments. It is how you respond to environmental changes and how you basically adapt to it.. that's where the idea of response and adaption came from.
Hope this Helps!! (I had a quiz on this once) </span>

Answer:
in cellular respiration food is oxidized to CO2 while O2 is reduced into H2O Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.Aerobic respiration, the process that does use oxygen, produces much more energy and doesn’t produce lactic acid. It also produces carbon dioxide as a waste product, which then enters the circulatory system
