5.
Individual organisms change in response to their
environment.
Variations are found among the members of a species.
Not all of the young in each generation will survive.
If an organism uses a structure more the structure will
be more developed and that trait can be passed on to
their offspring.
More than one answer is correct
The actions of the adult giraffe resulted in the
change of the phenotype. This change in
phenotype will be passed on to the offspring. This

Early breeders were interested in a dog with the greatest speed. They
carefully selected from a group of hounds the dog that ran the fastest.
From their offspring, the greyhound breeders again selected those
dogs that ran the fastest. By continuing this selection for those dogs
that ran faster than most of the hound dog population, they gradually
produced a dog that could run up to 64 km/h (40mph). Which graph
depicts this type of selection?
