Organisms have internal and external structures that function to support:

Plants living in Utah desert regions:

Animals take in information through:

• a. their brains

• b. books they read

• c. their senses

Some animals have one sense that is stronger than others. Bats send sound waves out to hit various objects. The soundwaves return to the bat and this information is processed by their brain. It helps them know where other objects and insects are. This process is called:

• a. sound wave transfer

• b. vibration

• c. echolocation

Fossils from long ago tell us:

• a. what color eyes the organism had

• b. if current organisms have structures that help them to survive.

• c. the type of organisms that lived long ago

If a paleontologist found ocean animal fossils up on a highland mountain, what might they conclude?

• someone probably carried ocean fossils up the mountain and left them there

• the area that is now mountains may have once been under the ocean

• fish and other organisms left the ocean to live on the mountain

• all of the above

If you found fossils of a particular bird in older layers of rock, but did not see the bird fossils in newer layers, and did not see that bird currently existing, what could you infer about that bird species?

• the bird species is extinct and became extinct after the last time period there was evidence it existed

• the birds may have flown away from the later layers

• The bird is now an endangered animal

• There never were any birds
