Answer the following question given this paragraph: The properties of cyclic hydrocarbons are generally quite similar to those of the corresponding open-chain compounds. So cycloalkanes (with the exception of cyclopropane, which has a highly strained ring) act very much like noncyclic alkanes. Cyclic structures containing five or six carbon atoms, such as cyclopentane and cyclohexane, are particularly stable. We will see in Chapter 16 "Carbohydrates" that some carbohydrates (sugars) form five- or six-membered rings in solution. Q: The properties of cyclic hydrocarbons are generally quite similar to those of the corresponding open-chain compounds. so cycloalkanes (with the exception of cyclopropane, which has a highly strained ring) act very much like noncyclic alkanes. cyclic structures containing five or six carbon atoms, such as cyclopentane and cyclohexane, are particularly what? Choices: - large - reactive - small - stable A:
stable

Answer the following question given this paragraph: structure in angiosperms consisting of male and female reproductive structures that attracts animal pollinators. Q: Angiosperms possess reproductive structures that attract animals that perform what role? Choices: - evolution - vegetation - isolation - pollination A:
pollination

Answer the following question given this paragraph: Any organic material can be made into electricity. But some materials are better than others. Wastes can be used, like almond shells. Biomass power is a great use of wastes. It's hard to use wastes as a consistent large scale source of energy though. Q: What kind of material that might otherwise go to a landfill can serve as the source of biomass power? Choices: - mechanical waste - microscopic waste - reactive waste - organic waste A:
organic waste
