Answer the following question given this paragraph: After the blood in the pulmonary capillaries becomes saturated with oxygen, it leaves the lungs and travels to the heart. The heart pumps the oxygen-rich blood into arteries, which carry it throughout the body. Eventually, the blood travels into capillaries that supply body tissues. These capillaries are called peripheral capillaries . Q: After the blood in the pulmonary capillaries becomes saturated with oxygen, it leaves the lungs and travels where? Choices: - to the lungs - to the kidneys - to the brain - to the heart A:
(A).
to the heart

(Q).
Answer the following question given this paragraph: If the rocks on one or both sides of a fracture move, the fracture is called a fault ( Figure below ). Faults can occur alone or in clusters. A cluster of faults creates a fault zone . Earthquakes happen when rocks break and move suddenly. The energy released causes an earthquake. Q: What is the fracture called when rocks on both sides move? Choices: - a crevice - a shear - a stress fracture - a fault A:
(A).
a fault

Answer the following question given this paragraph: Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms. They are the simplest class of hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. You can see an example of a saturated hydrocarbon in the Figure below . In this compound, named ethane, each carbon atom is bonded to three hydrogen atoms. In the structural formula, each dash (-) represents a single covalent bond, in which two atoms share one pair of valence electrons. Q: What are hydrocarbons that contain only single bonds between carbon atoms called? Choices: - caloric hydrocarbons - unsaturated hydrocarbons - carcinogenic hydrocarbons - saturated hydrocarbons A:
(A).
saturated hydrocarbons
