Q: Answer the following question given this paragraph: Energy that the sun and other stars release into space is called electromagnetic energy . This form of energy travels through space as electrical and magnetic waves. Electromagnetic energy is commonly called light. It includes visible light, as well as radio waves, microwaves, and X rays ( Figure below ). Q: Energy that the sun and other stars release into space is called what? Choices: - static energy - kinetic energy - mechanical energy - electromagnetic energy A:
A: electromagnetic energy

Q: Answer the following question given this paragraph: Igneous rocks are classified first by composition. Categories go from from felsic to ultramafic. Color can indicate composition. Q: What is the first classification of igneous rocks? Choices: - size - color - weight - composition A:
A: composition

Q: Answer the following question given this paragraph: One path of blood in the heart is through the right atrium and right ventricle. The right atrium receives oxygen-poor blood from the body. It pumps the blood into the right ventricle. Then the right ventricle pumps the blood out of the heart to the lungs. This path through the heart is part of the pulmonary circulation. Q: What structure of the heart receives oxygen-poor blood from the body, then pumps the blood into the right ventricle? Choices: - left ventricle - right ventricle - left atrium - right atrium A:
A: right atrium

Q: Answer the following question given this paragraph: The acidity of a solution is typically assessed experimentally by measurement of its pH. The pOH of a solution is not usually measured, as it is easily calculated from an experimentally determined pH value. The pH of a solution can be directly measured using a pH meter (Figure 14.4). Q: The acidity of a solution is typically assessed experimentally by measurement of its what? Choices: - mass - density - color - ph A:
A: ph
