Q: Answer the following question given this paragraph: Types of neurons include sensory neurons, motor neurons, and interneurons. Q: Types of neurons include sensory neurons, motor neurons, and? A:

OPTIONS:
- histones
- anions
- synapses
- interneurons

A: interneurons

input: OPTIONS:
- parts
- root
- gauges
- trophic Now, answer this question: Answer the following question given this paragraph: Energy is passed up a food chain or web from lower to higher trophic levels. However, generally only about 10 percent of the energy at one level is available to the next level. This is represented by the ecological pyramid in Figure below . What happens to the other 90 percent of energy? It is used for metabolic processes or given off to the environment as heat. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. Sometimes there may be a fifth trophic level, but usually there's not enough energy left to support any additional levels. Q: What are the "levels" in a food chain or web called? A:
A:
output: trophic

Answer the following question given this paragraph: Electronegativity Differences between Metals and Nonmetals An element's electronegativity provides us with a single value that we can use to characterize the chemistry of an element. Elements with a high electronegativity ( 2.2 in Figure 7.15 "Pauling Electronegativity Values of the ") have very negative affinities and large ionization potentials, so they are generally nonmetals and electrical insulators that tend to gain electrons in chemical reactions (i. , they are oxidants). In contrast, elements with a low electronegativity ( 1.8) have electron affinities that have either positive or small negative values and small ionization potentials, so they are generally metals and good electrical conductors that tend to lose their valence electrons in chemical reactions (i. , they are reductants). In between the metals and nonmetals, along the heavy diagonal line running from B to At in Figure 1.24 "The Periodic Table Showing the Elements in Order of Increasing ", is a group of elements with intermediate electronegativities ( ~ 2.0). These are the semimetals, elements that have some of the chemical properties of both nonmetals and metals. The distinction between metals and nonmetals is. Q: What are metals and good electrical conductors that tend to lose their valence electrons in chemical reactions called? A:
****
A:
reductants
