Answer the following question given this paragraph: That is the main difference between sexual and asexual reproduction. Sexual reproduction is combining genetic material from two parents, usually from two gametes. How the two cells combine may take many forms, but does not necessarily involve physical contact. Sexual reproduction produces offspring that are genetically distinct from other offspring and from their parents. Asexual reproduction produces offspring from just one parent. These offspring are genetically identical to that one parent. Q: What type of reproduction involves combining genetic material from two parents to create distinct offspring? Choices: - mild reproduction - bsexual reproduction - asexual reproduction - sexual reproduction A:
sexual reproduction
Answer the following question given this paragraph: Before lymph reaches the bloodstream, it passes through small oval structures called lymph nodes, which are located along the lymph vessels. Figure below shows where some of the body's many lymph nodes are concentrated. Lymph nodes act like filters and remove pathogens from lymph. Q: What act like filters and remove pathogens from lymph? Choices: - spine nodes - tissue nodes - electric nodes - lymph nodes A:
lymph nodes
Q: Answer the following question given this paragraph: Figure 14.5 Structures of the Ear The external ear contains the auricle, ear canal, and tympanic membrane. The middle ear contains the ossicles and is connected to the pharynx by the Eustachian tube. The inner ear contains the cochlea and vestibule, which are responsible for audition and equilibrium, respectively. Q: The cochlea and vestibul make up what part of the ear? Choices: - middle - upper - outer - inner A:
A: inner
Question: Answer the following question given this paragraph: U-235 nuclei can capture neutrons and disintegrate more efficiently if the neutrons are moving slower than the speed at which they are released. Fission reactors use a moderator surrounding the fuel rods to slow down the neutrons. Water is not only a good coolant but also a good moderator, so a common type of fission reactor has the fuel core submerged in a huge pool of water. This type of reactor is called a light water reactor or LWR. All public electricity generating fission reactors in the United States are LWRs. Q: What do fission reactors use to slow down the neutrons? Choices: - inertia - brake - control - moderator A:
Answer: moderator

Answer the following question given this paragraph: A: You can see that snow and sand have a different color. You can also feel that snow is softer than sand. Both color and hardness are physical properties of matter. Q: What are color and hardness physical properties of? Choices: - cells - ions - elements - matter A:
**Answer**
matter

Answer the following question given this paragraph: Any two waves in the same medium undergo wave interference as they pass each other. At the location where the two waves collide, the result is essentially a summation of the two waves. In some places, a wave crest from one source will overlap a wave crest from the other source. Since both waves are lifting the medium, the combined wave crest will be twice as high as the original crests. Nearby, a wave trough will overlap another wave trough and the new trough will be twice as deep as the original. This is called constructive interference because the resultant wave is larger than the original waves. Within the interference pattern, the amplitude will be twice the original amplitude. Once the waves pass through each other and are alone again, their amplitudes return to their original values. Q: What is it called when two waves in the same medium pass one another? Choices: - accumulation - frequency - synchrony - interference A:
**Answer**
interference
