Answer the following question given this paragraph: Basic to Bohr's model is the idea of energy levels. Energy levels are areas located at fixed distances from the nucleus of the atom. They are the only places where electrons can be found. Energy levels are a little like rungs on a ladder. You can stand on one rung or another but not between the rungs. The same goes for electrons. They can occupy one energy level or another but not the space between energy levels. Q: What are the areas located at fixed distances from the nucleus of the atom? Choices: - molar levels - atomic regions - orbit points - energy levels A:
energy levels

Answer the following question given this paragraph: Detritivores are decomposers that consume dead leaves, animal feces, and other organic debris that collects on the ground or at the bottom of a body of water. Examples of detritivores include earthworms and catfish. You can see another example in Figure below . Q: What is the term for decomposers that consume dead leaves, animal feces, and other organic debris collected on the ground or at the bottom of water? Choices: - scavengers - recyclers - consumers - detritivores A:
**Answer**
detritivores
Answer the following question given this paragraph: With fossil fuels becoming more expensive and less available, scientists are looking for other energy sources. Hydrogen has long been considered an ideal source, since it does not pollute when it burns. The problem has been finding ways to generate hydrogen economically. One new approach that is being studied is photoelectrolysis the generation of electricity using photovoltaic cells to split water molecules. This technique is still in the research stage, but appears to be a very promising source of power in the future. Q: What is the generation of electricity using photovoltaic cells to split water molecules called? Choices: - hybrid electricity - aqua-electricity - photovoltaic cells - photoelectrolysis A:
photoelectrolysis
