Answer the following question given this paragraph: All electric circuits have at least two parts: a voltage source and a conductor. They may have other parts as well, such as light bulbs and switches, as in the simple circuit seen in the Figure below . To see an animation of a circuit like this one, go to: http://www. rkm. com. au/animations/animation-electrical-circuit. html. Q: A voltage source and a conductor are common to all what? Choices: - magnets - thermometers - cooling circuits - electric circuits A:
electric circuits
Answer the following question given this paragraph: Figure 18.15 Both positive and negative objects attract a neutral object by polarizing its molecules. (a) A positive object brought near a neutral insulator polarizes its molecules. There is a slight shift in the distribution of the electrons orbiting the molecule, with unlike charges being brought nearer and like charges moved away. Since the electrostatic force decreases with distance, there is a net attraction. (b) A negative object produces the opposite polarization, but again attracts the neutral object. (c) The same effect occurs for a conductor; since the unlike charges are closer, there is a net attraction. Q: What type of polarization does a negative object create> Choices: - common polarization - simple polarization - negative polarization - opposite polarization A:
opposite polarization
Q: Answer the following question given this paragraph: Biomass is the mass of biological organisms. It is usually used to describe the amount of organic matter in a trophic level of an ecosystem. Biomass production involves using organic matter ("biomass") from plants to create electricity. Using corn to make ethanol fuel is an example of biomass generated energy. Biomass is generally renewable. Q: Biomass is the mass of biological what? Choices: - tissues - proteins - lipids - organisms A:
A: organisms
Question: Answer the following question given this paragraph: Caecilians The caecilian order is the amphibian order with the fewest species. Caecilians are closely related to salamanders. They have a long, worm-like body. They are the only amphibians without legs. Caecilians evolved from a four-legged ancestor but lost their legs later in their evolution. As adults, they often burrow into the soil. That's one reason why Caecilians tend to be less well known than other amphibians. microcaecilia. Q: What are the only amphibians without legs? Choices: - newts - crustaceans - porifera - caecilians A:
Answer: caecilians
