What is Biology?
The change of a living thing over time, usually in terms of increasing size or biological mass.
What is Growth?

What is a gene?
When Living things change into progressively different shapes or behaviros.
What is Development?

What is an Organism?
What viruses need host cells for.
What is Reproduction?
Where cells come from.
What are other cells?
A biological molecule that stores and passes on hereditary traits.
What is DNA?

What is a Stimulus?
