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? A:
OPTIONS:
- magnets
- thermometers
- cooling circuits

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> A:
OPTIONS:
- common polarization
- simple polarization
- negative polarization
- opposite polarization

Answer: opposite polarization

Question: 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? A:
OPTIONS:
- tissues
- proteins
- lipids
- organisms
Answer: organisms

input with options: 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? A:
OPTIONS:
- newts
- crustaceans
- porifera
- caecilians
output: caecilians

Problem: OPTIONS:
- assimilation
- hydration
- activation
- hybridization
Q: Answer the following question given this paragraph: Quantum-mechanical calculations suggest why the observed bond angles in H2O differ from those predicted by the overlap of the 1s orbital of the hydrogen atoms with the 2p orbitals of the oxygen atom. The mathematical expression known as the wave function, , contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals, LCAO, (a technique that we will encounter again later). The new orbitals that result are called hybrid orbitals. The valence orbitals in an isolated oxygen atom are a 2s orbital and three 2p orbitals. The valence orbitals in an oxygen atom in a water molecule differ; they consist of four equivalent hybrid orbitals that point approximately toward the corners of a tetrahedron (Figure 8.7). Consequently, the overlap of the O and H orbitals should result in a tetrahedral bond angle (109.5). The observed angle of 104.5 is experimental evidence for which quantummechanical calculations give a useful explanation: Valence bond theory must include a hybridization component to give accurate predictions. Note that orbitals may sometimes be drawn in an elongated "balloon" shape rather than in a more realistic "plump" shape in order to make the geometry easier to visualize. Q: This process of combining the wave functions for atomic orbitals is called what? A:
Answer:
hybridization
