Answer the following question given this paragraph: Triglycerides function as a long-term storage form of energy in the human body. Because of the long carbon chains, triglycerides are nearly nonpolar molecules and thus do not dissolve readily in polar solvents such as water. Instead, oils and fats are soluble in nonpolar organic solvents such as hexane and ethers. Q: What substances function as a long-term energy store in the human body and possess long carbon chains that prevent dissolving in water? Choices: - hydrocarbons - steroids - nanoparticles - triglycerides A:
**Answer**
triglycerides

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:
**Answer**
heat
