theory - ANSWER-an explanation that can be used to explain a broad set of
phenomena
hypothesis - ANSWER-a proposed explanation for a narrow set of phenomena
law - ANSWER-a state based on repeated experiment observations that describes
some sort of phenomenon of nature
Eukarya - ANSWER-organisms that have cells with nucleus
Archaea - ANSWER-single celled organisms without a nucleus
Neucloid - ANSWER-region where DNA is in Archaea

Chemotaxis - ANSWER-response to chemicals
Phototaxis - ANSWER-response to light
Macro evolution - ANSWER-the descent of different species from a common ancestor
over many generations
analogous structures - ANSWER-Body parts that share a common function, but not
structure
applied science - ANSWER-aims to use science to solve problems
basic science - ANSWER-seeks to expand knowledge regardless of the application
Adaptation - ANSWER-when organisms exhibit a "fit" to their environment.
Evolution - ANSWER-the process of gradual change during which new species arise
from older species
Micro evolution - ANSWER-changes in gene frequency in a population from one
generation to the next
mutagens - ANSWER-agents in the environment that can change DNA. causes
mutations.
