The feathers of a snowy owl gradually changed to white to allow it to blend in with its environment during the winter months (with snow). This inherited characteristic is an example of ________________

• Environmental Change

• Adaptation

• Variation

The environment around Manchester, England, changed during the Industrial Revolution. How did this change affect peppered moths living in the area?

• Natural selection favored moths with dark wings because predators could not see them on the soot-colored (dark) trees.

• Natural selection favored moths with white wings that were easy for predators to see.

• Natural selection favored moths with white wings because predators could not see them on the soot-colored (dark) trees.

• Natural selection caused moths with white wings to become extinct.

_______ developed the theory of acquired inheritance. He believed that an organism could change its body/appearance, and pass these changes along to their offspring (ex: a mom and dad with muscles will have a baby with muscles).

• Darwin

• Lamarck

• Mendel

• Watson

A virus killed most of the seals in the North Sea (e.g. dropped the population from 8000 to 800). In an effort to help preserve the species, scientists caught 20 of the remaining seals and used them to start a new population in the northwest Pacific Ocean. Which of the following statements would accurately describe the new population?

• The new seal population is genetically less diverse than the original population

• The new seal population is genetically more diverse than the original population

• There is equal genetic variety compared to the original population

• The "new" seals will turn into monsters and control the ocean.
