answers
Biological organization Ans✓✓-atom, molecule, organelle, cell, tissue, organ,
organ system, organism, population, community, ecosystem, biosphere
Prokaryote Ans✓✓-a small unicellular organism that lacks a nucleus and
membrane bound organelles; bacteria and archaea
Eukaryote Ans✓✓-a cell (or often multiple cells) with a nucleus and membrane-
enclosed organelles that have specified functions
What creates unity in the diversity of life? Ans✓✓-DNA
Unified because all organisms have DNA
Diverse because of the differences in DNA sequence
hierarchical organization Ans✓✓-Domain, Kingdom, Phylum, Class, Order, Family,

data analysis, publication, peer review
, Flexibility of the Scientific Process Ans✓✓-Scientists work through the first five
steps repeatedly until it is time to publish, when the researchers in that field build
consensus and then work toward societal benefits, at which point the scientists
may return to forming and testing hypotheses
control group Ans✓✓-In an experiment, the group that is not exposed to the
treatment; serves as a comparison for evaluating the effect of the treatment.
standard variable Ans✓✓-held constant for all subjects in an experiment
