Scientists found some fossil bones from an extinct animal. The scientists used the bones to make a model of the animal’s skeleton.

Based on the feature shown, which of these is the best conclusion the scientists can make?

• The animal lived in water.

• The animal blended in well with its environment.

• The animal had many offspring each year.

• The animal migrated long distances to find food.

Organisms have different types of behaviors. Some of these behaviors are

natural responses called instincts. Other behaviors are learned through

the use of an organism’s senses through interactions with the environment.

Which three behaviors are examples of instincts?

•  birds returning to a bird feeder for food

• monkeys using tools

• ants living in a colony

• sea turtles swimming

• geese flying in a group

Scientists study a fossil of an extinct fish. The scientists compare the

extinct fish to fish that are living today.

Which of these is the best conclusion the scientists can make about the

extinct fish?

• The extinct fish had fins on its body similar to the fins on many fish that are

  living today.

• The extinct fish had stripes on its skin similar to the stripes on some fish that

  are living today.

• The extinct fish could live for many years, similar to some fish that are living

  today.

• The extinct fish had many predators, similar to many fish that are living

  today

The picture shows two mice called pocket mice. Pocket mice can be born

with either light-colored fur or dark-colored fur. A group of pocket mice

lives in a habitat where there is light sandy soil and dark lava rocks. Mice

with light-colored fur blend in with the light sandy soil. Mice with

dark-colored fur blend in with the dark lava rocks.

Which habitat change would most likely benefit mice with dark-colored

fur and not help mice with light-colored fur?

• Dark lava rocks break into small pieces from weathering.

• Light sandy soil becomes very dry because of direct sunlight.

• Lava erupts from a volcano and then hardens into large areas of dark lava

  rocks.

• Light sandy soil blows around in the wind and covers up dark lava rocks.

The diagram shows four layers of sediment under the ground. A vertical shaft was dug and fossils were collected from each layer.

Which three statements can students make about these soil layers?

• Fossils collected from Layer 1 will be younger than those collected from

  Layer 4.

• Fossils collected from Layer 3 will contain organisms larger than those

  collected from Layer 2.

• Fossils collected from Layer 1 will be the same age as those collected from

  Layer 3.

• Fossils collected from Layer 4 will be older than those collected from Layer 2.

• Fossils collected from Layer 2 could be closely related to those collected from

  Layer 1.

Which of these most likely describes a behavior that an animal learns and

is not an instinct?

• A moth keeps flying around a bright light many times.

• A kitten makes purring sounds as a mother cat cleans its fur.

• A dog sits quietly and waits while its owner opens a bag of dog treats.

• A sea turtle returns to the location where it was hatched and lays its eggs

  there.

The diagram shows fossils in rock layers. Rock layer 5 formed first.

Which of these correctly compares the age of the fossil in rock layer 3 to fossils in the other rock layers?

• The fossil in rock layer 3 is younger than the fossils in rock layers 1 and 2.

• The fossil in rock layer 3 is the same age as the fossils in rock layers 2 and 4.

• The fossil in rock layer 3 is younger than the fossil in rock layer 2 and older

  than the fossil in rock layer 5.

• The fossil in rock layer 3 is older than the fossil in rock layer 2 and younger

  than the fossil in rock layer 5.

The diagram shows two cliffs that are located very close to each other.

Both cliffs have rock layers that contain fossils.

Which statement correctly compares the ages of the rock layers?

• Rock layer F is the same age as rock layer E.

• Rock layer J is younger than rock layer D.
