2.) Organelle - mitochondria, chloroplast, nucleus
3.) Molecular - water, glucose, DNA
4.) Atomic - hydrogen, carbon, nitrogen, oxygen
5,) Subatomic - protons, neutrons, electrons

environment . Organisms recognize certain chemicals as nutrients while ignoring others.
Homeostasis - Answer -Living systems have some capacity to change harmful
conditions into conditions more favorable to their continuing existence - the conversion
of chemical compounds.
Growth and Biosynthesis - Answer -Living systems go through phases during which
they make more of their own material.
,Genetic Material - Answer -Living systems contain genetic material (DNA and RNA) to
allow inherited traits.
Production - Answer -Living systems can reproduce & pass on genetic material.
Population Structure - Answer -Organism form populations. Of these organism capable
of sexual processes, a population is all those organisms that can interbreed with one
another.
Scientific Method - Answer -1.) Observation
2.) Hypothesis
3.) Experiment/Observation
4.) Conclusion
5.) Theory

New Paradigm - Answer -Darwinism, Classical Mendelian genetics, Germ Theory of
Disease, Modern Evolutionary Theory
Antibiotics - Answer -Penicillin, doxy, etc.

buds in children. It is still used today in cancer treatments.
