BIO 152 EXAM 1 WITH CORRECT
ANSWERS 2025
adaptation correct answers >> change in genome;
permanent, generation to generation
acclimation correct answers >> change their physiology
temporarily; not generation to generation
species correct answers >> individuals that can exchange
genetic material through interbreeding
gene pool correct answers >> all the alleles present in all
individuals in a species
population genetics correct answers >> study of genetic
variation in natural populations
populations correct answers >> interbreeding groups of
organisms of the same species living in the same geographical
area
somatic mutation correct answers >> occur in body's tissues
germ-line mutation correct answers >> occurring in
reproductive cells, passed on to ancestors
, neutral mutations correct answers >> neither harmful or
advantageous, occur in regions that aren't functionally important
advantageous mutations correct answers >> mutations that
improve their carrier's chances of survival and reproduction; ones
that result in adaptation
allele frequencies correct answers >> rates of occurrence of
alleles in populations
Hardy-Weinberg equilibrium correct answers >> reproductive
success; no migration; no mutation; sufficiently large population;
mate at random
evolution correct answers >> over time, species accumulate
changes; as a result decedents differ from their ancestors
natural selection correct answers >> non-random process,
selects for heritable traits that grants fitness advantages (aka
reproductive success)
preconditions for evolution through natural selection correct
answers >> variation must exist in the population; variation
must lead to differential reproductive success; variation must be
heritable
artificial selection correct answers >> non-random process
by which traits become more/less common in a species because
humans are selecting which organisms have offspring
