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

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

Genetic mutations are the direct cause of which of the following?

• Aliens

• Super heroes

• Variations

• 9th grade behaviors

If Easter eggs were living species of organisms, their different colors would be considered:

• Adaptations

• Variations

• Different species

• Extinct species

The peppered moth's color camouflaged it on the light colored tree bark. It's color was an example of a/n

• Variation

• Dominant trait

• Recessive trait

• Adaptation

Where are hereditary traits stored in all organisms?

• In the blood

• In the brain

• In the DNA

• In the heart

Why might it be helpful for a species to have a lot of variations?

• They can't be seen by predators

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

• It is helpful in asexual reproduction

• They don't recognize each other

If a sick person takes an antibiotic but it doesn't kill all of the bacteria causing the sickness, what might explain this?

• Variations in the bacteria allowed some organisms to be less affected by the antibiotic

• Bacteria cannot be killed by antibiotics

• You cannot cure a bacterial infection

• Bacteria do not cause sicknesses

One female salmon can lay hundreds of eggs. Why doesn't the salmon population increase dramatically?

• Salmon reproduce asexually

• Most offspring do not grow up to reproduce

• Salmon eggs don't hatch

• Salmon are extinct

Another term for Natural Selection is:

• Breeding

• Commensulism

• Communism

• Survival of the fittest

Individuals that are well adapted to their environment will survive and produce:

• Fewer mutations
• Stronger genes
• More offspring
• Better traits
