Answer the following question given this paragraph: Fruit-eating bats ( Figure below ) also receive food from plants. In return, they help these plants spread their seeds. When bats consume fruit, they also consume the seeds within the fruit. Then they carry the seeds in their guts to far-away locations. Q: Fruit-eating bats receive food from plants and, in return, help these plants by doing what? Choices: - pollinating seeds - fertilizing them - protecting them - spreading seeds A:
**Answer**
spreading seeds

Answer the following question given this paragraph: 22.3 Magnetic Fields and Magnetic Field Lines Einstein is said to have been fascinated by a compass as a child, perhaps musing on how the needle felt a force without direct physical contact. His ability to think deeply and clearly about action at a distance, particularly for gravitational, electric, and magnetic forces, later enabled him to create his revolutionary theory of relativity. Since magnetic forces act at a distance, we define a magnetic field to represent magnetic forces. The pictorial representation of magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. As shown in Figure 22.15, the direction of magnetic field lines is defined to be the direction in which the north end of a compass needle points. The magnetic field is traditionally called the Bfield. Q: What is the magnetic field traditionally referred to as? Choices: - m-field - charged field - spicule - bfield A:
**Answer**
bfield

Answer the following question given this paragraph: Single-displacement reactions are a subset of redox reactions. In this subset, what is oxidized and what is reduced? Give an example of a redox reaction that is not a single-displacement reaction. Q: Single-displacement reactions are a subset of what? Choices: - gravitational reactions - kinetic reactions - particle reactions - redox reactions A:
**Answer**
redox reactions

Answer the following question given this paragraph: After doing the research, the farmer will try to answer the question. She might think, "If I don't plow my fields, I will lose less soil than if I do plow the fields. Plowing disrupts the soil and breaks up roots that help hold soil in place. " This answer to her question is a hypothesis . A hypothesis is a reasonable explanation. A hypothesis can be tested. It may be the right answer, it may be a wrong answer, but it must be testable. Once she has a hypothesis, the next step is to do experiments to test the hypothesis. A hypothesis can be proved or disproved by testing. If a hypothesis is repeatedly tested and shown to be true, then scientists call it a theory . Q: What is another name for a reasonable explanation for something that might be formed near the beginning of a scientific inquiry into a problem? Choices: - experiment - conclusion - theory - hypothesis A:
**Answer**
hypothesis
