Answer the following question given this paragraph: In science, sound is defined as the transfer of energy from a vibrating object in waves that travel through matter. Most people commonly use the term sound to mean what they hear when sound waves enter their ears. The tree above generated sound waves when it fell to the ground, so it made sound according to the scientific definition. But the sound wasn't detected by a person's ears if there was nobody in the forest. So the answer to the riddle is both yes and no!. Q: In science, what is defined as the transfer of energy from a vibrating object in waves that travel through matter? Choices: - energy - photons - vibration - sound A:
sound
Answer the following question given this paragraph: Remember that individuals do not evolve. Their genes do not change over time. The unit of evolution is the population. A population consists of organisms of the same species that live in the same area. In terms of evolution, the population is assumed to be a relatively closed group. This means that most mating takes place within the population. The science that focuses on evolution within populations is population genetics . It is a combination of evolutionary theory and Mendelian genetics. Q: What is the unit of evolution? Choices: - species - community - biome - population A:
population
Q: Answer the following question given this paragraph: A related process to diffusion is the effusion. Effusion is the process of a confined gas escaping through a tiny hole in its container. Effusion can be observed by the fact that a helium-filled balloon will stop floating and sink to the floor after a day or so. This is because the helium gas effuses through tiny pores in the balloon. Both diffusion and effusion are related to the speed at which various gas molecules move. Gases that have a lower molar mass effuse and diffuse at a faster rate than gases that have a higher molar mass. Q: Both diffusion and effusion are related to the speed at which what objects move? Choices: - electricity - copper molecules - solids - gas molecules A:
A: gas molecules
Question: Answer the following question given this paragraph: Continuous Capillaries The most common type of capillary, the continuous capillary, is found in almost all vascularized tissues. Continuous capillaries are characterized by a complete endothelial lining with tight junctions between endothelial cells. Although a tight junction is usually impermeable and only allows for the passage of water and ions, they are often incomplete in capillaries, leaving intercellular clefts that allow for exchange of water and other very small molecules between the blood plasma and. Q: What is the most common type of capillary? Choices: - channels - large - ending - continuous A:
Answer: continuous

Answer the following question given this paragraph: The kidneys filter blood and form urine. They are part of the urinary system, which also includes the ureters, bladder, and urethra. Q: What organs filter blood and form urine? Choices: - the appendix - the spleen - the liver - the kidneys A:
**Answer**
the kidneys

Answer the following question given this paragraph: Mushrooms and other fungi obtain energy from other organisms. That's why you often see fungi growing on a fallen tree; the rotting tree is their source of energy ( Figure below ). Q: Mushrooms and other fungi obtain energy from what? Choices: - the soil - the sun - the air - other organisms A:
**Answer**
other organisms
