An oil spill decreases the number of zooplankton in the Chesapeake day.

How will the oil spill most likely affect the osprey and eagle populations?

• Osprey and eagle populations will increase.

• Osprey and eagle populations will decrease.

• Osprey population will increase and the eagle population will decrease.

• Osprey population will decrease and the eagle population will increase

The illustration shows an ecosystem consisting of the Sun, plants, and a cow.

How is the energy from the primary source of energy transferred through the ecosystem?

• The Sun shines on the cow, directly providing it with energy to eat the plants.

• The cow produces food, which is the source of energy that the plants use to grow toward the Sun.

• The Sun shines on the plants, directly providing them with energy to produce food that the cow will eat.

• The cow produces waste products, which provide energy to the soil that the plants use to grow toward the Sun.

A population of leopards lives on a rocky, snow-covered mountain. After many generations, some members of this population have eyes located higher on their foreheads.

How does this new trait most improve their chance of survival over the rest of the leopard population?

• They can stay lower behind cover while stalking prey.

• They can protect their eyes better from wind and snow.

• They can better see small animals hiding in holes between rocks.

• They can hunt for longer periods because of improved night vision.

Many plants have flowers that attract butterflies, bees, and other pollinators.

What advantage does pollination by an animal have for the plant?

• Direct pollen transfer is most likely to produce seeds.

• More nutritious seeds for the animal will be produced.

• Larger seeds that are most likely to sprout will be produced.

• More pollen will be produced so than the pollinator can eat some.

Susan has been assigned to build a model of a plant cell. She has many materials to help her build her model: plastic wrap, a plastic sandwich bag, aluminum foil, different kinds of dry pasta, stiff cardboard, and pipe cleaners.

She selects the stiff cardboard to represent which outside supporting part of the plant cell.

• A cell membrane

• mitochondria

• cell wall

• nucleus

Which difference between plant and animal cells explains why amoeba cells can change shape and algal cell cannot?

• Plant cells lack a nucleus to control movement.

• Plant cells have a cell wall and animal cells do not.

• Plant cells have chloroplasts and animal cell do not.

• Animal cells allow cytoplasm to move through the cell wall.

What is the function of the plasma membrane?

• to produce proteins

• to help the cell move

• to storage energy molecules

• to control what enters the cell

What role do the bones of the skeletal system play in breathing?

• Bones store extra air.

• Bones make up the diaphragm.

• Bones surround and protect the lungs.

• Bones squeeze the lungs to force air out.

Asma built a model of a human backbone, following a diagram in her science textbook. She made her first model by stringing wooden beads on a pipe cleaner. When she bent the pipe cleaner, the beads rubbed together. Next she placed rings of soft foam in between the wooden beads. Now the beads did not rub together .

What are these models meant to show?

• how a backbone is made of bones

• how discs in the backbone protect the vertebrae as they move

• how many vertebrae are in the backbone

• how many discs are between the vertebrae

• how to make an art project using the backbone as a model

Which three bunnies are most likely the babies of these two parent rabbits?
