a)
basketball
b)
natural selection
c)
evolution
d)
mutation
10.
A lion makes more cubs than the Sahara Desert can support (there's not enough prey around), so only a few of the cubs survive to become adults. They live on to reproduce.
Of the four parts of natural selection, which is this an example of?
a)
overproduction
b)
genetic variation
c)
selection
d)
adaptation
11.
Due to a mutation, some jaguars inherit larger jaw sizes than other jaguars within that population and this trait is passed down from parent to offspring. This gives those jaguars an advantage when it comes to hunting down turtles as prey.
Of the four parts of natural selection, which is this an example of?
a)
overproduction
b)
genetic variation
c)
selection
d)
adaptation
12.
Tigers with larger paws hunt deer more easily to survive in an environment where resources are limited. As a result, the tigers with larger paws are “selected” (the larger paws become more common in the next generation of tigers).
Of the four parts of natural selection, which is this an example of?
a)
overproduction
b)
genetic variation
c)
selection
d)
adaptation
13.
Populations of species which do not adapt to their environment can eventually become...
a)
stronger
b)
humans
c)
extinct
d)
angry
14.
In both the past and the present, humans have selected plants or animals for breeding based on desirable traits. This process is known as...
a)
artificial selection
b)
natural selection
c)
farming
d)
cropping
15.
Genetic variation can arise from a random change in the DNA of a gene.  The change is called a(n)
a)
mutation
b)
gene flow
c)
gene pool
d)
