The red maple tree is found in Florida. Seasonal changes cause the red maples in Florida to lose their leaves around the same time every year. The leaves grow back during the next spring season. How do red maple trees in other parts of the world most likely respond to seasonal changes?

• They never lose their leaves and instead stay green all year long.

• They lose their leaves during daylight and grow them back overnight.

• They lose their leaves during one part of the year and never grow them back.

• They lose their leaves during one part of the year and grow them back during another.

Keri observed the leaves of the same type of tree and noticed that some looked healthier than others. Keri wonders what makes the leaves different. She wants to plan an investigation to find an answer. What do all investigations begin with?

• a data table

• a prediction

• a conclusion based on evidence

• a question about the natural world

What do all producers have in common?

• They are all herbivores.

• They all make food with energy from the Sun.

• They all move from place to place to get their food.

• They all gain energy from consuming other animals.

Coral vine is a plant humans imported to Florida because of its beautiful flowers. The vine was planted in many areas around the state. It is able to grow rapidly and take over surrounding areas even when it is planted in poor soil or in an area with air pollution. Other plants in these areas die because they receive little or no water, sunlight, and nutrients from the soil after the vine takes over. Which characteristic makes the coral vine a threat to Florida’s environment?

• Coral vines are flowering plants.

• Coral vines require good soil to grow.

• Coral vines take over surrounding areas quickly.

• Coral vines are unable to grow near air pollution.

Raymond wraps three jars with three different materials: paper, cotton, and wool. Then he fills the jars with hot water of the same temperature. Raymond concludes that wool is better than cotton or paper at keeping a liquid warm. What evidence would best support Raymond’s conclusion?

• The final water temperature was coolest in the jar wrapped in wool.

• The final water temperature was coolest in the jar wrapped in cotton.

• The final water temperature was warmest in the jar wrapped in wool.

• The final water temperature was warmest in the jar wrapped in cotton.

The resurrection fern can be found growing on oak trees in Florida forests. During the winter the resurrection fern turns brown and curls up. During warmer parts of the year it unfolds and turns green and lush. Which is a possible explanation for the resurrection fern turning brown and curling its leaves?

• It helps them reproduce.

• It helps them spread their seeds.

• It helps camouflage them from predators.

• It helps them survive cooler temperatures.
