Answer the following question given this paragraph: Lipids are made of long chains consisting almost solely of carbon and hydrogen. These long chains are called fatty acids. Fatty acids may be saturated or unsaturated. Figure below shows an example of each type of fatty acid. Q: What are made of long chains consisting almost solely of carbon and hydrogen? Choices: - nucleic acids - enzymes - proteins - lipids A:
lipids

Answer the following question given this paragraph: An example of a disaccharide is sucrose (table sugar), which consists of the monosaccharides glucose and fructose ( Figure below ). Other common disaccharides include lactose ("milk sugar") and maltose. Monosaccharides and disaccharides are also called simple sugars . They provide the major source of energy to living cells. Q: What are monosaccharides and disaccharides also called? Choices: - simple chemicals - basic sugars - complex sugars - simple sugars A:
simple sugars

Answer the following question given this paragraph: The Hardy-Weinberg theorem states that, if a population meets certain conditions, it will be in equilibrium. In an equilibrium population, allele and genotype frequencies do not change over time. The conditions that must be met are no mutation, no migration, very large population size, random mating, and no natural selection. Q: Which theorem states that, if a population meets certain conditions, it will be in equilibrium? Choices: - hardy- jacksons theorem - hardy - henkel theorem - hardy - zeiss theorem - hardy-weinberg theorem A:
hardy-weinberg theorem

Answer the following question given this paragraph: Hydrocarbons are compounds that contain only carbon and hydrogen. The carbon atoms in hydrocarbons may share single, double, or triple covalent bonds. Unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms. They are classified on the basis of their bonds as alkenes, aromatic hydrocarbons, or alkynes. Q: Hydrocarbons are made up of carbon and what else? Choices: - silicon - nitrogen - helium - hydrogen A:
hydrogen
