Both the respiratory system and the digestive system involve the uptake of necessary molecules from an animal’s surroundings. Alveoli are tiny sacs that aid in the exchange of carbon dioxide and oxygen in the lungs. Intestinal villi are tiny projections along the lining of the intestines used to take in nutrients from food passing through.

Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?

• Endocrine

• Integumentary

• Immune

• Circulatory

Answer explanation

The circulatory system transports blood to and from the heart and the rest of the body. Nutrients and gases, such as oxygen, are dissolved in the blood. The circulatory system must interact with the respiratory and digestive systems to transport the nutrients and gases in the blood throughout the body.

A student makes a model of the sun-Earth system by swinging a ball around her head. Using this model, the student is trying to explain how Earth stays on a path around the sun.The student explains that this path is the result of —

• The magnetic attraction between Earth and the sun

• Potential energy stored in Earth that originated in the sun

• The gravitational attraction between the sun and Earth

• Electromagnetic energy from the sun pulling on Earth

Major surface currents of the ocean are shown in the diagram.

Ocean currents affect weather patterns by —

• regulating when tides occur in coastal areas

• trapping heat at the equator to regulate the global climate

• distributing heat from the uneven absorption of solar energy

• increasing the rate of evaporation to transport water to areas experiencing droughts
