Which of the following explains adaptation.
A. An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.
B. The species as a whole changes their characteristics.
C. Beneficial traits allow organism to survive and pass on those traits
D. New characteristics arise in a species as needed. If these traits are helpful, they are passed down.
_________ is when an animal stands out in its environment.
A. warning coloration
B. mimicry
C. protective resemblance
D. camouflage
A physical or behavioral trait that helps an organism survive and reproduce in its environment is called a what?
A. An adaptation
B. A response to a stimulus
C. A mutation
D. Evolution
When an organism has a trait that allows it to blend in with its environment, we call that ____.
A. mimicry
B. camouflage
C. lucky
D. sonic hedgehog gene
If species A and B have very similar genes and proteins, what is probably TRUE?
A. species A and B share a relatively recent common ancestor
B. species A evolved independently of species B for a long period
C. species A is younger than species B
D. species A is older than species B
The colors & patterns on a turtles shell help it blend in with the forest floor. This adaptation is called:
A. hibernation.
B. behavior.
C. migration.
D. camouflage.
What do we call structures that no longer perform their original function?
A. Natural Selection
B. Analogous Structure
C. Vestigial Structure
D. Homologous Structure
What would indicate that a series of different fossils showed the evolution of a species?
A. the fossils were identical
B. the fossils were found in the same layers of rock
C. the fossils show similarities
D. the fossils were completely different
An owl is mostly nocturnal meaning it hunts and is active at night.
A. Behavioral Adaptation
B. Structural Adaptation
Mutations are important because they bring about
A. death of the organism in which they develop
B. genetic variation needed for a population to evolve
C. benefits for the individual, not for the population
D. Hardey-Weinberg equilibrium within a population
A population of rabbits grows rapidly from one year to the next. Then one year, a disease strikes approximately one fourth of the adult rabbits. The disease remains with the population in the years that follow.
As explained by Darwin’s theory, which of these conditions allows the rabbit population to evolve by natural selection?
_
A. The disease affects adult and juvenile rabbits equally.
B. The disease reduces the ability of the rabbits to reproduce.
C. Some rabbits are resistant to the disease, and they pass the resistance to their offspring.
D. No rabbits are resistant to the disease, and all die when the disease strikes them.
When an organism has a trait that makes it resemble another species, either in looks or behavior, we call that ____
A. mimicry
B. camouflage
C. copycatting
D. sonic hedgehog gene
________ enable an organism to survive in its environment.
A. adaptations
B. natural selections
C. divergence
D. extinctions
When an environment changes faster that an species can adapt, the most likely outcome is…
A. …biological evolution.
B. …voluntary mutation
C. …species extinction
D. …selective breeding
Ostrich wings are examples of
A. homologous structures
B. vestigial structures
C. adaptations
D. traits
