Answer the following question given this paragraph: When bacteria are destroyed by leukocytes, pyrogens are released into the blood. Pyrogens reset the body's thermostat to a higher temperature, resulting in fever. How might pyrogens cause the body temperature to rise?. Q: When bacteria are destroyed by leukocytes, what are released into the blood? Choices: - carcinogens - proteins - sporozoans - pyrogens A:
pyrogens

Answer the following question given this paragraph: As we saw when we studied States of Matter , the driving force for particles in the liquid phase to escape into the gas phase depends on both the temperature and identity of the substance. The vapor pressure of a liquid is a measure of this ability. Specifically, vapor pressure is the pressure exerted by a vapor that is in equilibrium with its solid or liquid phase. For substances with a stronger drive to enter the gas phase, more vapor particles will be present in the same amount of space, resulting in a higher pressure. At a given temperature, the vapor pressures of various liquids depends primarily on the strength of intermolecular attractions between individual particles. Figure below shows the relative vapor pressures of several different substances. Q: The vapor pressures of various liquids depends primarily on the strength of what kind of attractions between individual particles? Choices: - diffusion - gravitational - outer molecular - intermolecular A:
intermolecular

Answer the following question given this paragraph: Bacteria that cause foodborne illnesses include Salmonella , a bacterium found in many foods, including raw and undercooked meat, poultry, dairy products, and seafood. Campylobacter jejuni is found in raw or undercooked chicken and unpasteurized milk. Several strains of E. coli can cause illnesses, and are found in raw or undercooked hamburger, unpasteurized fruit juices and milk, and even fresh produce. Vibrio is a bacterium that may contaminate fish or shellfish. Listeria has been found in raw and undercooked meats, unpasteurized milk, soft cheeses, and ready-to-eat deli meats and hot dogs. Most of these bacterial illnesses can be prevented with proper cooking of food and washing of hands. Q: Most of these bacterial illnesses can be prevented with proper cooking of food and washing what? Choices: - vegetables - hair - teeth - hands A:
hands
