microbiology: study of microscopic organisms
2) virology: study of viruses
3) physiology: normal functions of living organisms (ex: kidney function or
bird)
3 jobs associated with ( correct answers ) 1)
biology researcher
2) teacher
3) physician
primary literature ( correct answers )
scientists write a paper describing experiments/fieldwork they've
done (usually peer reviewed)
ex: scientific journals
secondary literature ( correct answers ) Literature that reports on
the research findings of other scientists
ex: review articles, text books
gray literature ( correct answers ) unpublished
reports ex: student's writing a paper on
something
2 main things that affect plant growth
( correct
answers ) nitrogen and
phosphorous
light = most plant growth ( correct answers )
red light
discovery based science ( correct answers ) experimentation that
does not require a preconceived hypothesis. In some cases, the goal is to
collect data to be able to formulate a hypothesis
documentation of natural processes
hypothesis based science ( correct answers ) a form
of science that begins with a specific explanation that is then tested
Null Hypothesis (H0) ( correct answers ) A statement of "no
difference." Research Hypothesis (H1) ( correct answers ) difference
between two variables
, standardized variable ( correct answers ) held constant for all
subjects in an experiment so we can compare (aka control variable)
replication ( correct answers ) reduces probability that a result
happened by chance and supports the idea that result is due to IV

example of natural selection
natural selection ( correct answers ) traits/characteristics that improve the
survival of individuals in a population will increase while traits that put
individuals at a disadvantage will decrease and possibly disappear
population ( correct answers ) A group of individuals that belong to the
same species and live in the same area
fitness ( correct answers ) Ability of an organism to survive and
reproduce in its environment
phylogenetic species concept ( correct answers ) defines a
species as the smallest group of individuals that share a common ancestor
(looks at genetics)
biological species concept ( correct answers ) Definition
of a species as a population or group of populations whose members have
the potential to interbreed in nature and produce viable, fertile offspring, but
