The photograph shows a two-toed sloth. These slow-moving organisms cannot outrun or outclimb predators, so they spend most of their time hanging from branches in trees. The sloths eat the leaves and flowers from these trees. Two-toed sloths often have a greenish tint on their fur because algae grow on their bodies. Which of these is the most likely reason the algae are able to help two-toed sloths survive?

by allowing the sloths to blend in with the trees to hide from predators

by providing sloths with easy access to another food source

by making sloths more attractive to other sloths to encourage mating

by helping to keep the body temperatures of sloths cooler during hot weather

A student uses a microscope to observe a single-celled organism that can move. The organism contains a nucleus and many chloroplasts. Based on the observations, the student claims the organism is not a bacterium. Which observation best supports the student’s claim?

The organism performs photosynthesis.

There are advantages to both sexual and asexual reproduction. Which of these describes the most likely advantage of sexual reproduction?

More variation among offspring.

large numbers of offspring are produced at once.

increases the chance of harmless mutations.

When an athlete began running, both her breathing and heart rates increased. The athlete’s breathing and heart rates increased as she was running because the athlete needed to:

transport more oxygenated blood to her muscles.

exhale more oxygen from her lungs.

decrease the temperature of her skin.

increase the amount of carbon dioxide in her blood.

Students are studying the behavior of matter as a gas. Each sample is at the same temperature and in different 1.0-liter rigid containers. The number of particles shown in the diagram is proportional to the number of particles in each sample. Which three statements about the gas in the containers are true?

The gas particles in Container 1 will be the easiest to compress.

The gas particles in Container 3 will be the hardest to compress.

The gas particles in Container 3 will move slower than the gas particles in Container 1.

The gas particles in Container 2 will move faster than the gas particles in Container 1.

If the temperature is decreased in each container, the pressure will decrease in each container.

Which of these describes a behavioral adaptation that will increase the probability that a species will survive?

A mother bear stays with her cubs for a year and a half until they learn skills to live on their own.

A bird has brown feathers that help it blend with the ground where its nest is located.

A giraffe has long legs that help it reach leaves growing at the tops of acacia trees.

A moth has large dark spots on its wings that resemble eyes and scare away predators.

Which change in the carbon cycle would have the greatest effect on the amount of carbon dioxide in the atmosphere?

a 50% increase in the burning of fossil fuels

a 10% increase in the amount of decomposing organic matter

a 20% increase in land used for agriculture

a 15% increase in the number of trees planted

Two types of cells are shown. Organelles found in both cells are labeled. Which two claims about cell function are supported by the evidence in the diagram?

Both types of cells produce proteins.

Both types of cells can control what enters and exits the cell.

Both types of cells are unable to produce energy.

Both types of cells can store excess water.

Both types of cells can maintain a rigid shape.

Students are learning about the functions of different parts in cells. The students model a cell part with a screen that sorts large objects from small objects. When objects of different sizes are placed on the screen, the screen allows the smaller objects to pass through it but not the larger objects. Which of these cell functions is most likely being modeled?

passive transport across the cell membrane

energy production by the mitochondria

photosynthesis inside the chloroplast

In a type of bean plant, the trait for yellow pods (B) is dominant to the trait for green pods (b). A plant that is heterozygous for yellow pods is crossed with a plant that has green pods. An incomplete Punnett square of the cross is shown. Which statement correctly describes the probability that offspring of this cross will display certain traits?

50% yellow pods and 50% green pods

75% yellow pods and 25% green pods

A student was reading about the gases in air. Ozone helps protect Earth from harmful ultraviolet rays that come from the sun. Certain types of pollution created by humans have caused a hole in the ozone layer. This hole is over the South Pole and could become larger if this type of pollution increases.
Which question should the student ask to determine if ozone is an elemental molecule?

What is the color of the molecule?

What is the shape of the molecule?

What elements are present in the molecule?

How many atoms are present in the molecule?
