Koalas rarely need to drink because they get most of their water from the eucalyptus leaves they eat.
C
Alligators have eyes positioned to peek out just above the waterline.
D

B
genetic variation
C
phenotypic characteristics
D

11) Which best describes the relationship between genetic variation and an organism’s ability to adapt to its environment?
A
A population of organisms with little genetic variation is better able to adapt to changes in their environment than organism
B
The environment causes genetic variation in a population of organisms, which allows them to adapt to their environment.
C
Organisms of a population have certain traits that enable them to adapt to changes in the environment, survive, and pass thes
D
Genetic variations in a population of organisms result in individuals with similar genetic traits and the ability to adapt to
