What is the primary function of this body system?

• The protection of vital organs from injury

• The chemical breakdown of food into smaller pieces

• The transport of nutrients, water, and oxygen to body cells

• The production of hormones that regulate growth and metabolism

A group of scientists studies some trees in a pine forest. In the densely forested areas, the trees were within 1 m of each other. The scientists observed that these trees had dead branches near the ground. They measured the height above the ground at which the first living branches were found on different-sized trees in the forest. Then they repeated this procedure on the same kind of trees in an open meadow. This graph summarizes the scientists' data.

Which interference is best supported by these data?

• Pine trees in a dense forest can grow taller than pine trees in an open meadow

• Pine trees in a dense forest compete for sunlight with the surrounding trees.

• Pine trees in a dense forest are part of a less-complex food web than pine trees in an open meadow

• Pine trees in a dense forest have more living branches than pine trees in an open meadow.

Which of the following best describes a relationship in this grassland?

• Badgers are top predators because they eat upland sandpipers and beetles

• A producer-consumer relationship exists between lupines and ants

• A predator-prey relationship exists between beetles and ground squirrels

• Upland sandpipers are primary and secondary consumers because they eat grasses and grasshoppers

To fight a bacterial infection, a patient was given antibiotic to take for 10 days. After the patient finished taking the antibiotics as directed, almost all the bacteria were killed. After another 10 days, the patient was sick again with the same type of infection. What most likely happened?

• A few bacteria survived the antibiotics and stopped reproducing

• The patient's high fever inactivated the antibiotic, allowing the surviving bacteria to grow rapidly

• The antibiotic slowed the life cycle of the bacteria

• Some of the bacteria were resistant to the antibiotic, and they reproduced

An ecosystem that is not sustainable can break down when a natural disaster occurs. This can lead to organisms in the ecosystem either leaving the area or dying off. Increased biodiversity results in a more sustainable ecosystem because-

• a greater number of plant species means that there is less barren land

• a greater variety of species present allows more organisms to adapt after changes occur

• the transition area between two ecosystems is narrower

• there are fewer species to be affected by environmental stresses

How would the absence of sunlight affect a plant's ability to grow?

• The plant could not absorb nutrients from soil.

• The plant could not absorb water from the soil.

• The plant could not produce carbon dioxide and oxygen.

• The plant could not produce food through photosynthesis.

Which describes how organisms process materials to gain energy for life processes?

• Oxygen is broken down in a chemical reaction with sugars to release energy.

• Sugars are broken down in a chemical reaction with oxygen to release energy.

• Vitamins and minerals are used to build complex molecules that store energy.

• Vitamins and minerals are used to break down complex molecules that store energy.

Which most accurately describes how plants and animals obtain the energy they need for growth and survival?

• Molecules are broken down during respiration to release stored energy.

• Molecules are broken down during photosynthesis to release stored energy.

• Animals produce energy through photosynthesis, while plants produce energy through respiration.

• Animals produce energy through respiration, while plants produce energy through photosynthesis.
