Q.1
Genetic drift is change in the allele frequency of a population due to...
random chance
natural selection
non-random mating (sexual selection)
artificial selection
Q.2
What is speciation?
combining of two species to form one with different traits
Intentional breeding designed to maintain a desired trait
timing of mating that prevents normal sexual selection
A population splits and accumulates different genes in the new groups
Q.3
A phenotype that improves an organism’s chance of survival in their environment is considered a(n) ____________.
natural selection
adaption
speciation
All of above
Q.4
Individuals undergo evolution.
True
False
Q.5
Over generations of time apart on different islands with different food sources, the separated populations of Galapagos finches accumulated genetic differences until each group had different beaks. This is an example of _____.
natural selection
genetic drift
adaptation
speciation
Q.6
Brown mice survive and reproduce in their desert environment better than white mice because owls can see and eat the white mice more easily. In this situation, what part of the environment is doing the selecting?
predator
soil composition
mouse fur color
sexual preferences
Q.7
Natural selection results in change in a population's _____________ traits over time.
inherited
acquired
Q.8
This makes an organism more suited to its enviornment
species
lifespan
adaptation
mutation
Q.9
What would indicate that a series of fossils represent evolution?
the fossils were identical
the fossils were found in the same layers of rock
the fossils show similarities
the fossils were completely different
Q.10
Why do embryologist study embryos?
to see if they are related
to understand adaptations

Q.12
Change over time is
evolution
generation
growth

Q.13
Natural selection is
survival of the fittest
humans change
two species are the same
more animals survive
Q.14
Which of the following is not a piece of evidence for evolution?

is not reproducing
Q.16
What is one reason that strawberries are surviving in the winter season?
they have larger leaves
they have genetic variations allowing them to be resistant to cold
they reproduce more

Q.17
Genetic diversity
allows for a small population
allows for similar physical features
allows for genetic diversity
