Answer the following question given this paragraph: Saturated hydrocarbons contain only single bonds between carbon atoms. They are the simplest hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. You can see an example of a saturated hydrocarbon in Figure below . Each carbon atom is bonded to three hydrogen atoms in this compound, which is named ethane. Q: What are the simplest hydrocarbons? Choices: - unsaturated hydrocarbons - complex carbohydrates - fossil fuels - saturated hydrocarbons A:
saturated hydrocarbons
Answer the following question given this paragraph: Thermal energy is the total energy of moving particles of matter. The transfer of thermal energy is called heat. Therefore, a heating system is a system for the transfer of thermal energy. Regardless of the type of heating system in a home, the basic function is the same: to produce thermal energy and transfer it to air throughout the house. Q: What do you call the transfer of thermal energy? Choices: - formation - humidity - precipitation - heat A:
heat
Q: Answer the following question given this paragraph: Infrared light is light with the longest wavelengths and lowest frequencies. You can't see infrared light, but you can feel it as heat. Besides the sun, flames and living things give off infrared light. Q: What type of light can you feel as heat but not see and has the longest wavelengths and lowest frequencies? Choices: - solar light - ultraviolet light - thermal light - infrared light A:
A: infrared light
Question: Answer the following question given this paragraph: The four planets closest to the Sun - Mercury, Venus, Earth, and Mars - are the inner planets . They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backwards and spins the slowest of all the planets. Q: Which planet is closest to the sun? Choices: - Earth - Jupiter - Venus - mercury A:
Answer: mercury

Answer the following question given this paragraph: Epistasis is when a gene at one location (locus) alters the phenotypic expression of a gene at another locus. Epistasis takes place when the action of one gene is modified by one or several other genes. These genes are sometimes called modifier genes . The gene whose phenotype is expressed is said to be epistatic , while the phenotype that is altered is said to be hypostatic . Sometimes hypostatic phenotypes are completely suppressed. Epistatic genes are not dominant over the genes they alter or suppress. Dominance refers to an interaction between alleles of the same gene, not different genes. Q: What is it called when a gene at one location (locus) alters the phenotypic expression of a gene at another locus? Choices: - exogenous - epigenesis - spontaneous mutation - epistasis A:
**Answer**
epistasis
Answer the following question given this paragraph: Figure below shows the main gases in air. Nitrogen and oxygen make up 99 percent of air. Argon and carbon dioxide make up much of the rest. These percentages are the same just about everywhere in the atmosphere. Q: What makes up 99 percent of air? Choices: - oxygen and dioxide - phosphorus and oxygen - dioxide and nitrogen - nitrogen and oxygen A:
nitrogen and oxygen
