8. Which statement best describes how antibiotics affect cellular homeostasis?
A Antibiotics interfere with the transport of intracellular and extracellular materials.
B. Antibiotics decrease the rate of cellular respiration in animal cells by producing oxygen. C. Antibiotics increase the rate of DNA replication in human cells by forming nucleotides.

The meaningful differences between organisms in a population are genetic. Variations in the genome of members of a population arise through mutation. Occasionally, a mutation occurs in an individual that is beneficial, that helps that organism be better able to survive and repoduce in its current environment.
