Scallan Science Module 2 Review

Which statement best explains why fossils are useful to scientists?

• They can tell the exact year something was alive many years ago.

• They can show what the present day environment is like in a far away location on earth.

• They can help describe what types of organisms were present long ago and the environment they likely lived in.

• They can show what types of organisms are present all over the world today.

Which statement best explains what happens to organisms when the environment changes?

• All organisms that were living in that environment will die when their habitats in the environment change.

• All organisms that were living in that environment will continue to live in their habitats in that environment.

• Some organisms will survive and stay in that environment and some will migrate to new locations.

• The organisms with characteristics that allow them to survive in the new environment will stay, others will migrate or may even die.

Which statements describe animals living in groups? 

Select the two correct answers

• All animals live in groups because it helps them to survive.

• All animals live in small groups that help them to collect food.

• Some animals live in small groups that may help to protect themselves from predators.

• All animals live in large groups that help them to protect themselves and their young from predators.

• Some animals live in groups to help them cope with changes in their environment.

Which claims can best be supported by the fossil record in the figure? 

Select the two correct answers.

• The type of animal that formed fossil Y existed for only 50 million years.

• The type of animal that formed fossil W existed for the longest period of time.

• The type of animal that formed fossil X was the last of the animals to die out

• The type of animal that formed fossil Y died out more than 350 million years ago.

• The type of animal that formed fossil X could be found on Earth more than 300 million years ago.

A road is being built through a grassy area where lined snakes live.

 In which way will this road most likely affect the snakes in the area?

• More snakes will die because they will have less grass to live in.

• More snakes will die because new predators will move into the area.

• More snakes will survive because they will be able to find more food.

• More snakes will survive because they will have better places to sun themselves.

Black carp are fish that were brought to the United States in the 1970s. Some black carp escaped into rivers during floods. They began to eat mussels and snails. The way mussels and snails feed helps clean the water in a river.

Which effects will most likely be caused by introducing black carp into new ecosystems?

Select the two correct answers

• Other types of fish will find new food sources

• Some types of snails will disappear from the ecosystem.

• The water in rivers will become dirty as black carp eat more mussels.

• Plants that live in rivers will be healthier because fewer nutrients will be in the water.

• The number of large predators will increase because they will have more kinds of fish to eat.

A scientist studied layers of rock on the side of a cliff. In the top layer of rock, she found fossilized sand dunes. In the middle layer of rock, she found fossils of coral, clamshells, and shark teeth. In the bottom layer of the rock, she found fossils of fern leaves. 

What is the correct order of the environments of the three layers, from oldest to youngest?

• desert, ocean, forest

• desert, forest, ocean

• ocean, forest, desert

• forest, ocean, desert

River otters have short legs, webbed feet with claws, and strong tails. Their ears can close to keep water out. They also have thick fur that keeps water from reaching their skin. They eat animals that live in the water, such as fish, frogs, and turtles. Animals such as alligators and hawks hunt and eat river otters.

What environment is a river otter best suited for?

• Desert, because river otters do not need a lot of water

• Tundra, becauser river otters have fur and can stay warm

• Wetlands, because river otters are best suited for water and land

• Marine, because river otters only live in the ocean
