14. Disagree; although they have very dif-
ferent characteristics, both dog breeds
are a result of thousands of years of
artificial selection. Humans bred the
ancestors of today’s wolves to produce
the variety of dogs we have today.
Wolves and different kinds of dogs are
closely related.
15. Disagree; antibiotics may kill many
bacteria, but the bacteria that remain
are more resistant to the antibiotics.
This use of antibiotics promotes the
evolution of resistant populations of
bacteria. Over a period of time, diseases can’t be controlled as effectively
with the same antibiotics. This makes
diseases harder to treat and more people may get them.
16. Disagree; by definition, a population
is made up of all the members of the
same species that live in the same
place at the same time. A community
is made up of all the populations in
the same place at the same time. If
organisms are members of the same
species and live in the same community, they all are part of the same
population.

INTERPRETING OBSERVATIONS
11. The hawks would see the dark gray
rabbits more easily than the white
rabbits when snow was on the ground
because the white rabbits would
blend in. Therefore, the hawks probably ate more gray rabbits than white
rabbits. More white rabbits lived to
reproduce.
12. During most months the remaining
dark gray rabbits would blend in with
the surroundings better than white
rabbits would. Hawks would eat
fewer dark rabbits than white rabbits.
The rabbit population would change
to include more gray rabbits because
they would more likely survive to
reproduce.
13. More rabbits are born than can survive. The rabbits in a population differ in the traits that they have. Some
of these traits give rabbits advantages
that help them survive. Rabbits can
then reproduce and pass these traits
on to their offspring. Each generation
REFINING CONCEPTS
17. Insects are difficult to control because
they are small and can get into a home
easily, they don’t need much food to
survive, they move quickly and can
hide in small spaces easily, they reproduce quickly, and they can become
resistant to insecticides.
18. No; all ecosystems are interconnected. Answers may vary. Sample
answer: Humans in the city rely on
resources, such as water and food,
from other ecosystems. Anything
that affects water, air, land, or living
things can affect the city’s food and
water supply. Also, air in the city
comes from other ecosystems. A
