Answer the following question given this paragraph: Visible Light The range of photon energies for visible light from red to violet is 1.63 to 3.26 eV, respectively (left for this chapter's Problems and Exercises to verify). These energies are on the order of those between outer electron shells in atoms and molecules. This means that these photons can be absorbed by atoms and molecules. A single photon can actually stimulate the retina, for example, by altering a receptor molecule that then triggers a nerve impulse. Photons can be absorbed or emitted only by atoms and molecules that have precisely the correct quantized energy step to do so. For example, if a red photon of frequency f encounters a molecule that has an energy step,. Q: What kind of light ranges from red to violet? Choices: - infrared light - x rays - ultraviolet light - visible light A:
visible light
Answer the following question given this paragraph: Cellular respiration uses oxygen in addition to glucose. It releases carbon dioxide and water as waste products. Cellular respiration actually "burns" glucose for energy. However, it doesn't produce light or intense heat like burning a candle or log. Instead, it releases the energy slowly, in many small steps. The energy is used to form dozens of molecules of ATP. Q: In addition to glucose, what gas is used during cellular respiration? Choices: - methane - hydrogen - nitrogen - oxygen A:
oxygen
Q: Answer the following question given this paragraph: Volcanic eruptions can be devastating, particularly to the people who live close to volcanoes. Volcanologists study volcanoes to be able to predict when a volcano will erupt. Many changes happen when a volcano is about to erupt. Q: Who study volcanoes to be able to predict when a volcano will erupt? Choices: - vocologists - virologists - ornithologists - volcanologists A:
A: volcanologists
Question: Answer the following question given this paragraph: Ecosystems need energy. Many ecosystems get their energy in the form of sunlight, which enters the ecosystem through photosynthesis . This energy then flows through the ecosystem, passed from producers to consumers . Plants are producers in many ecosystems. Energy flows from plants to the herbivores that eat the plants, and then to carnivores that eat the herbivores. The flow of energy depicts interactions of organisms within an ecosystem. Q: Energy from sunlight enters many ecosystems through what process? Choices: - multiplication - reproduction - isolation - photosynthesis A:
Answer: photosynthesis
*Question*
Answer the following question given this paragraph: cell that transmits electrical impulses in the nervous system; commonly called nerve cell. Q: What type of cell transmits electrical impulses in the nervous system? Choices: - toxin cell - Large Cell - trace cell - nerve cell A:
**Answer**
nerve cell
Answer the following question given this paragraph: Insects are capable of a surprising range of behaviors. Most of their behaviors, such as flying and mating, are instinctive. These are behaviors that don't need to be learned. They are largely controlled by genes. However, some insect behaviors are learned. For example, ants and bees can learn where food is located and keep going back for more. Q: What types of incest behaviors are controlled by genes? Choices: - byproduct behaviors like flying and mating - psychological behaviors like flying and mating - physical behaviors like flying and mating - instinctive behaviors like flying and mating A:
instinctive behaviors like flying and mating
