BSC 101 Wodika: Exam One questions with
accurate answers
Contrast "blending" and Mendelian models of inheritance Ans✓✓✓
Mendelian is all or nothing and blending is a mix of both(incomplete
dominance)
Define analogous structures Ans✓✓✓ Structures of different species
having similar or corresponding function but not from the same common
ancestor
define biology Ans✓✓✓ the study of living organisms and their
interactions with one another and their environments
Define Eukaryote Ans✓✓✓ An organism made up of cells that have a
nucleus enclosed by a membrane.
define gene flow Ans✓✓✓ movement of alleles from one population to
another(pollen or animals eating seeds from one location and pooping in
another)
define genetic drift Ans✓✓✓ Changes in gene pools due to randomness
or chance events. More observable in smaller population. (only 5
bunnies reproduce and it happens to be five brown bunnies which makes
more brown bunnies). Not more fit to reproduce it just happens
, Define genotypic ratio Ans✓✓✓ the number of times a genotype would
appear in the offspring after a test cross
Define homeostasis Ans✓✓✓ the ability of an organism to maintain
constant internal conditions
Define homologous structures Ans✓✓✓ structures that are shared by
related species and that have been inherited from a common ancestor
Define hypothesis Ans✓✓✓ -Are not guesses.
-They are based on prior knowledge.
-Plausible explanations that have not been tested yet.
Define independent, dependent, control variable, control group, and
experimental group Ans✓✓✓ -independent: what you change
-dependent: what is changed as a result of the IV
-control: what is kept the same among all experiments
-control group: group that is left in an environment it would naturally
occur in
-experimental group: group experimented on
Define iterative in science Ans✓✓✓ series of experiments that circle
back to answer the same question to form a deeper understanding of the
topic(think the game of pinball)
