The caterpillars of monarch butterflies eat milkweed leaves. Milkweed leaves contain sap that is toxic to many animals but not to monarch butterfly caterpillars. This sap makes the monarch butterfly caterpillars toxic to predators and protects them from being eaten. Which of these is an inherited trait of monarch butterfly caterpillars? (5.10B)

• The size of the milkweed leaves that the caterpillars eat

• The ability of the caterpillars to eat toxic leaves without being harmed

• The number of milkweed leaves the caterpillars eat each day

• The number of leaves on the milkweed plants the the caterpillars visit each summer

The table shows characteristics of two different types of birds that live in similar forest environments.

Which statement explains an advantage of a bone in the macaw's tongue that the hornbill does NOT need?

• It helps macaws catch and chew small mammals and crustaceans.

• It helps macaws break open and eat tropical fruits and nuts.

• It helps macaws make large holes in trees to reach insects to eat.

• It helps macaws swallow whole prey.

The tallest trees in a rain forest are removed for lumbar. This increases the amount of light on the forest floor. The table shows information about fungi and ferns that grow on the forest floor.

Which statement explains why one organism is better adapted to the removal of the tall trees?

• The fungi are better adapted because they have spores that grow better in the dark.

• The ferns are better adapted because they have strong root systems.

• The fungi are better adapted because they can get energy from decaying trees.

• The ferns are better adapted because they can get energy from the sun.

Lacewings are insects that hatch from eggs. Which of these correctly compares the lacewing life cycle with the frog life cycle?

• Adult lacewings lay eggs, but adult frogs give birth to live larvae.

• When they hatch, young lacewings and young frogs look different from their adult forms.

• When they hatch, both lacewings and frogs have long legs for jumping.

• Both adult lacewings and adult frogs have more legs than they had as larvae.

• Listens to music daily

• Has a scar on her left arm

• Plays an instrument really well

• Green eyes

Deltas are large landforms found along coastlines. What process forms deltas?

• Cementation of sediments by rivers.

• Deposition of sediments by rivers.
• Erosion of sediments by ocean waves.

• Deposition of sediments by ocean waves.

Describe what the difference is between Model 1 and Model 2. What landform is each model trying to represent, and what force made the two different land formations?

A group of students wants to build a desert garden at school. They need soil that allows water to drain away easily for the desert plants in this garden. The students test different soils to determine how much water passes through and how much water remains in each soil as shown in the table.

Based on the table, which types of soils are best to use to build the garden?

• Clay and sand

• Sand and gravel

• Gravel and silt

• Silt and clay
