What internal adaptation do plants have that allow the transportation of water?

• Leaves

• Petals

• Root

• Xylem

What can we hypothesize if a plant had no xylem?

• It would move to another place for water.

• It could not survive.

• It would live stronger cause the vacuole would have all the water it needs.

• Nothing would happen, the xylem is not important to survival of plant.

• Bones that are heavy for speed

Hollow bones in birds is a perfect example of?

• How birds fly

• How birds find food

Why would different organisms have different types of bones?

• That is the way organisms are made to help reproduce.

• There is no real reason why organisms have different types of bones.

What can we hypothesize about organisms that live in the water that do not have gills?

• They will die due to drowning.

• They have another adaptation that allows them to breathe and therefore survive in the water.

• Those organisms don't exist.

• All of the above

Sharks and dolphins are both animals that live in the ocean. Dolphins, like other marine mammals, frequently come above water for air to get needed oxygen. Sharks, like many other fish, never have to leave the water for air. Which of the following best explains why sharks do not have to leave the water for air?

• Sharks do not need oxygen to live

• Sharks’ gills extract oxygen from the water.

• Sharks have lungs that store oxygen.

• Sharks absorb oxygen through their skin.
