This is my very last biology class assignment and I would appreciate all help with the answers.
Thx in advance.
Multiple Choice
1. Evolution is defined as
a mutation that causes an "unfit" outcome
survival of the fittest
to turn 360 degrees
change over time
2. What is an example of looking at biogeography as evidence for evolution?
comparative anatomy
marsupial versus placental animals
snow-preserved organisms
developing embryos from different species
3. Where are fossils formed? (choose the most correct answer)
in ice, snow, tar pits, and quick sand
in water, tree sap, quick sand, and peat bogs
in tar pits, ice, peat bogs, and water
in quick sand, snow, sand, and decaying plant tissue
4. A missing link is
when two organisms have structures that look the same
when two organisms have structures that do the same function
the absence of a fossil in an intermediate step of evolution
usually found in sedimentary rock
5. The definition of a vestigial feature is
when DNA is used to compare closely related species
a hipbone in whales
a structure that seems to have no purpose
a structure that has a relative and absolute date
6. What event in Darwin's life marked the beginning of his major research on evolution?
pre-medical school and Edinburgh University in Scotland
clergy school at Cambridge
growing peas in the monastery garden
traveling around the world aboard the HMS Beagle
7. What natural selection event occurred to change the population of the peppered moth?
The industrial revolution polluted the lichens and turned them dark.
The farmers used DDT year after year without switching pesticides.
The peppered moths began mating with other moths.
There was an inversion mutation in the moth's chromosomes.

A
B
C
D
9. Which statement is true about mutations?
Mutations always have a negative effect on an organism.
Mutations don't always affect the organism.
Mutations always have an effect on an organism, either positive or negative.
Mutations have a positive effect on an organism.
10. What is the name for the mutation in which a sequence of DNA is backwards?
inversion mutation
insertion mutation
deletion mutation
point mutation
11. Two species breeding at different times describes which of the following isolating mechanisms?
ecological
behavioral
temporal
mechanical
12. Geographic barriers lead to which evolutionary outcome?
sympatric speciation
allopatric speciation
hybrid sterility
gametic isolation
13. Which of the following scenarios describes a genetic drift situation?
A tiger eats the rabbits that are the slowest runners.
A peppered moth is noticed by a bird and then eaten.
A flood kills many of the shorter deer.
A dolphin avoids being eaten due to its bright warning colors.
14. In the laboratory assignment, what did the holes represent in the Styrofoam container?
the population
a generation of time
the selecting force
the survivors
15. The horse hoof is used as an evidence of evolution in which of the following ways?
as a vestigial feature
in comparative anatomy
in the fossil record
in biogeography
16. Comparing the structure of a human arm to the structure of an alligator arm is an example of comparing?
fossils
analogous structures
vestigial features
homologous structures
17. If the number of birds in a certain population shift from being found in a variety of colors to having only the darker colors, which type of natural selection would this be?
directional
stabilizing
disruptive
straight
18. Which type of speciation occurs when a physical or chemical sign is required before a species will mate?
temporal
behavioral
gametic
hybrid sterility
19. Identify the correct term for the following definition: "A catastrophic event occurs and, by chance, changes the traits in the population."
founder effect
isolating mechanisms
bottleneck effect
mechanical
20. Sympatric speciation refers to a type of
geographic barrier
chemical barrier
catastrophic barrier
reproductive barrier
