Answer: maintenance of internal conditions within certain
boundaries
◉ maintain homeostasis.
Answer: living organisms need to keep themselves stable with
regard to temperature, moisture level, acidity, and other factors
◉ Evolution.
Answer: descent of organisms from common ancestors, with the
development of generic and phenotypic changes over time that
make them more suited to the environment
◉ Natural Selection.
Answer: mechanisms of evolution caused by environmental
selections of organisms. most fit to reproduce. results in adaptation
