Q: Q: Which organisms break down either organic or inorganic molecules to supply energy for the cell? Read this paragraph and choose the correct option from the provided answers: Chemotrophic organisms break down either organic or inorganic molecules to supply energy for the cell. Some chemotrophic organisms can also use their organic energy-supplying molecules as a carbon supply, which would make them chemoheterotrophs. Choices: - photoreactive organisms - asexual organisms - spicule organisms - chemotrophic organisms A:
A: chemotrophic organisms

Q: Q: Which particle of an atom has a positive electric charge? Read this paragraph and choose the correct option from the provided answers: A proton is a particle in the nucleus of an atom that has a positive electric charge. All protons are identical. It is the number of protons that gives atoms of different elements their unique properties. Atoms of each type of element have a characteristic number of protons. For example, each atom of carbon has six protons, as you can see in Figure below . No two elements have atoms with the same number of protons. Choices: - electron - nutron - nucleus - proton A:
A: proton

Q: Q: The temperature at which the individual ions have enough kinetic energy to overcome the attractive forces that hold them in place is called? Read this paragraph and choose the correct option from the provided answers: The Relationship between Lattice Energies and Physical Properties The magnitude of the forces that hold an ionic substance together has a dramatic effect on many of its properties. The melting point, for example, is the temperature at which the individual ions have enough kinetic energy to overcome the attractive forces that hold them in place. At the melting point, the ions can move freely, and the substance becomes a liquid. Thus melting points vary with lattice energies for ionic substances that have similar structures. The melting points of the sodium halides (Figure 8.3 "A Plot of Melting Point versus the Identity of the Halide for the Sodium Halides"), for example, decrease smoothly from NaF to NaI, following the same trend as seen for their lattice energies (Figure 8.2 "A Plot of Lattice Energy versus the Identity of the Halide for the Lithium, Sodium, and Potassium Halides"). Similarly, the melting point of MgO is 2825C, compared with 996C for NaF, reflecting the higher lattice energies associated with higher charges on the ions. In fact, because of its high melting point, MgO is used as an electrical insulator in heating elements for electric stoves. Figure 8.3 A Plot of Melting Point versus the Identity of the Halide for the Sodium Halides. Choices: - occurring point - boiling point - last point - melting point A:
A: melting point
