What is an ecosystem?
All diversity of life is organized by this on a phylogenetic tree.
What are domains?
(bacteria, archaea and eukarya)
Developing a scientific understanding of a natural phenomenon typically begins by
What is an observation?
Atoms held together by chemical bonds.
What is a molecule?
Monomers of this are amino acids.
What is a protein?
This is the basic unit of life.

What is a dichotomous key?
The variable which a researcher manipulates.
What is the independent variable?
The bonds that hold water molecules together.
What are hydrogen bonds?
Something that does not dissolve in water.
What is hydrophobic?

What is an acid?
The negatively charged subatomic particles surrounding an atom.
What are electrons?
Evolutionary history and relationships among a species or group of species
What is phylogeny?
The study of the interactions of DNA and RNA and how they are regulated.
What is molecular biology?
