• A zebra's stripes allow it to confuse its predators.

• A frog's large hind legs allow it to jump from danger.

• A cat sleeps on a sofa to avoid the vacuum cleaner.

• extinction

• Natural Selection

A grizzly bear survives because he is well-adapted to his environment. When he reproduces, he passes on those traits to his offspring. This process is called __________.

Why might it be useful for a species to have a lot of variations (differences)?

• They cannot be seen by predators.

• If the environment changes, they might be better able to adapt to the changes.

• It is helpful in asexual reproduction.

• They don't recognize each other.
