Answer the following question given this paragraph: The vapor pressure of a solution is lower than that of the pure solvent at the same temperature. This decrease in vapor pressure is one example of a colligative property . Colligative properties are properties of solutions that depend only on the concentration of dissolved particles and not on their identity. Q: What are the properties of solutions called that depend only on the concentration of dissolved particles and not on their identity? Choices: - platyhelminth properties - platyhelminth properties - platyhelminth properties - colligative properties A:
(Answer)
colligative properties

Answer the following question given this paragraph: The largest known virus, called mimivirus, is so large that scientists first mistook it for a bacterium. It was first discovered in amoeba, in 1992, and was identified as a virus in 2003. Scientists believe that mimivirus may cause certain types of pneumonia in humans. The core contains DNA, with the majority of the DNA in genes, and only 10% DNA of unknown function ("junk" DNA). Q: What is the largest known virus? Choices: - polyomavirus - influenza virus - pneumonia virus - mimivirus A:
(Answer)
mimivirus

Answer the following question given this paragraph: One way mammals lose excess heat is by increasing blood flow to the skin. This warms the skin so heat can be given off to the environment. That's why you may get flushed, or red in the face, when you exercise on a hot day. You are likely to sweat as well. Sweating also reduces body heat. Sweat wets the skin, and when it evaporates, it cools the body. Evaporation uses energy, and the energy comes from body heat. Animals with fur, such as dogs, use panting instead of sweating to lose body heat (see Figure below ). Evaporation of water from the tongue and other moist surfaces of the mouth and throat uses heat and helps cool the body. Q: How do dogs lose body heat? Choices: - barking - sweating - eating - panting A:
(Answer)
panting
