Q: Many viral diseases can be prevented by giving people what? Read this paragraph and choose the correct option from the provided answers: Many viral diseases can be prevented by giving people vaccines (see Figure below ). A vaccine is a substance that contains pathogens such as viruses. The pathogens have been changed in some way so they no longer cause disease. However, they can still provoke a response from the host's immune system. This results in immunity, or the ability to resist the pathogen. Vaccines have been produced for the viruses that cause measles, chicken pox, mumps, polio, and several other diseases. Choices: - Lactose - pesticides - cancers - vaccines A:

Q: Where are bile acids, needed to emulsify lipids, stored in the body? Read this paragraph and choose the correct option from the provided answers: Triglycerides in the diet are digested in the small intestine. Since lipids are not water-soluble, they are emulsified with the help of bile acids, which are produced by the liver and stored in the gall bladder. Bile acids are cholesterol-derived steroids that also contain a water-soluble component. The nonpolar region of these acids can interact with triglycerides, and the water-soluble portion allows the entire complex to dissolve in the aqueous environment within the body. Choices: - liver - womb - cerebellum - gallbladder A:
gallbladder
