Answer the following question given this paragraph: The drummer in Figure below is hitting the drumheads with drumsticks. This causes the drumheads to vibrate. The vibrations pass to surrounding air particles and then from one air particle to another in a wave of energy called sound energy . We hear sound when the sound waves reach our ears. Sound energy can travel through air, water, and other substances, but not through empty space. That's because the energy needs particles of matter to pass it on. Q: What energy, produced by vibrations, cannot travel through empty space? Choices: - light - heat - plasma - sound A:
sound
Answer the following question given this paragraph: Primary Lymphoid Organs and Lymphocyte Development Understanding the differentiation and development of B and T cells is critical to the understanding of the adaptive immune response. It is through this process that the body (ideally) learns to destroy only pathogens and leaves the body's own cells relatively intact. The primary lymphoid organs are the bone marrow and thymus gland. The lymphoid organs are where lymphocytes mature, proliferate, and are selected, which enables them to attack pathogens without harming the cells of the body. Q: The primary lymphoid organs are the bone marrow and what else? Choices: - pinneal gland - thyroid - kidneys - thymus gland A:
thymus gland
Q: Answer the following question given this paragraph: Weathering changes solid rock into pieces. These pieces are called sediments. Sediments are described in the chapter Earth's Materials and Crust . Sediments are different sizes of rock particles. Boulders are sediments; so is gravel. At the other end, silt and clay are also sediments. Weathering may also cause the minerals at the Earth's surface to change form. The new minerals that form are stable at the Earth's surface. There are two types of weathering, mechanical and chemical. These are discussed in the next two concepts. Q: Over time, what changes solid rock into pieces? Choices: - metamorphosis - creep - leaching - weathering A:
A: weathering
Question: Answer the following question given this paragraph: Q: The function of which organ is to filter blood and form urine? Choices: - liver - lungs - gallbladder - kidneys A:
Answer: kidneys

Answer the following question given this paragraph: If water gets hot enough, it starts to boil. Bubbles of water vapor form in boiling water. This happens as particles of liquid water gain enough energy to completely overcome the force of attraction between them and change to the gaseous state. The bubbles rise through the water and escape from the pot as steam. Q: When water particles become hot enough to overcome the force of attraction between them, what happens to the water? Choices: - it freezes - it pools - it evaporates - it boils A:
**Answer**
it boils
