At different places on Earth, depending on elevation, air pressure varies. Which of the following reflects the pressure at any point on Earth?

• carbon dioxide levels in the air

• moisture (water vapor) in the air

• the weight of the atmosphere above that elevation

• the strength of Earth’s magnetic field at that elevation

Vivian placed an ice cube in a tray of warm water. The following picture shows her investigation.

Which statement describes the energy transfer that happens in Vivian’s investigation?

• Energy in the form of heat is transferred from the ice cube to the water by radiation.

• Energy in the form of heat is transferred from the water to the ice cube by radiation.

• Energy in the form of heat is transferred from the ice cube to the water by conduction.

• Energy in the form of heat is transferred from the water to the ice cube by conduction

The organization of the human body includes both nervous tissue and muscle tissue. What do both nervous tissue and muscle tissue have in common?

• Each tissue is found in only one organ in an organism.

• They are both found in the same organ inside an organism.

• Each tissue is made of groups of similar cells that work together.

• They are organized into organ systems that help an organism live.

The survival of a cell depends on the cell maintaining homeostasis. What is most likely to happen to a cell if homeostasis is not maintained?

• The cell will immediately divide.

• Cell processes will continue unchanged.

• The cell will eliminate wastes more efficiently.

• Many chemical reactions in the cell will slow down or even stop.
