-organism
-population - ANS-Population- includes organisms which include all other levels of
organization (chapter 1)
What term is used to describe the total amount and types of proteins contained within a
cell or organism? - ANS-Proteome (chapter 1)
Conducting research without a preconceived hypothesis is called - ANS-Discovery
based science
What is the purpose of using a control group in scientific experiments? - ANS-A
researcher can compare the results in the experimental group and control group to
determine if a single variable is causing a particular outcome in the experimental group
The passage of DNA from one species to another different species is an example of
vertical descent with modification.

(different species), then this would be a community.
Many people are sending their saliva to Ancestry.com and 23andme to find out their
ancestry. These companies look at 600,000 sites in your DNA and compare it to others.
What are these tests doing?
a. Comparing different species.
