Which best compares the respiratory system to the circulatory system?
The respiratory system transports oxygen to cells, while the
circulatory system provides oxygen for cells.

system transports oxygen to cells.
The respiratory system breaks down food for cell energy, while the
circulatory system rids the body of waste.

A litter of kittens have traits that are similar to both the mother cat and
the father cat. Which best explains this situation?
The kittens are provided the same kind of milk from their mother as
they grow.
The kittens inherit some of their traits from their mother and some
from their father.

A simple food chain includes hawks, lizards, and insects. Which will most
likely happen to the lizard and hawk populations if a pesticide is sprayed
to kill the insects, and the lizard and hawk populations cannot find other
food in this ecosystem?
Both the lizard population and the hawk population will increase.
Both the lizard population and the hawk population will decrease.
The lizard population will increase, but the hawk population will
decrease.
The lizard population will decrease, but the hawk population will
increase.
In a food chain, foxes are consumers of rabbits and mice. If the mice
population suddenly decreases, what will most likely happen to the
number of foxes?
The number of foxes will increase because they will eat fewer rabbits.
The number of foxes will stay the same because they will eat more
rabbits.
The number of foxes will decrease because they will be eaten by the
rabbits.
The number of foxes will decrease because they will only have one
remaining food source.
