input: OPTIONS:
- pollenation
- differentiation
- mutualism
- commensalism Now, answer this question: Answer the following question given this paragraph: Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. One species typically uses the other for a purpose other than food. For example, mites attach themselves to larger flying insects to get a "free ride. " Hermit crabs use the shells of dead snails for homes. Q: What is the name of the symbiotic relationship in which one species benefits while the other species is not affected? A:
A:
output: commensalism

Answer the following question given this paragraph: Cells, like these nerve cells, do not work in isolation. To send orders from your brain to your legs, for example, signals pass through many nerve cells. These cells work together to perform a similar function. Just as muscle cells work together, bone cells and many other cells do as well. A group of similar cells that work together is known as a tissue. Q: When orders are sent from your brain to your legs, these signals pass through what type of cells? A:
****
A: nerve cells

Answer the following question given this paragraph: until all atoms have octets. Because some atoms will lose electrons and some atoms will gain electrons, there is no overall change in the number of electrons, but individual atoms acquire a nonzero electric charge. Those that lose electrons become positively charged, and those that gain electrons become negatively charged. Charged atoms are called ions. Because opposite charges attract (while like charges repel), these oppositely charged ions attract each other, forming ionic bonds. The resulting compounds are called ionic compounds and are the primary subject of this chapter. The second way for an atom to obtain an octet of electrons is by sharing electrons with another atom. These shared electrons simultaneously occupy the outermost shell of more than one atom. The bond made by electron sharing is called a covalent bond. Covalent bonding and covalent compounds will be discussed in Chapter 4 "Covalent Bonding and Simple Molecular Compounds". Q: Because opposite charges attract, oppositely charged ions attract each other to form what? A:
OPTIONS:
- nuclear bonds
- particle bonds
- soluble bonds
- ionic bonds
ionic bonds
