Answer the following question given this paragraph: Protozoa are one-celled organisms with a nucleus, making them eukaryotic organisms. They cause diseases such as malaria. Malaria is a serious disease that is common in warm climates. The protozoa infect people when they are bit by a mosquito. More than a million people die of malaria each year. Other protozoa cause diarrhea. An example is Giardia lamblia ( Figure below ). Q: _________ are one-celled organisms with a nucleus which cause diseases such as malaria. Choices: - fungi - mosquitos - larvae - protozoa A:
protozoa

Answer the following question given this paragraph: Some pathogens spread through food or water. When harmful bacteria contaminate food, they cause foodborne illness, commonly called food poisoning. An example of a pathogen that spreads through water is the protozoan named Giardia lamblia, described in Table above . It causes a disease called giardiasis. Q: Illnesses caused by bacteria in food are commonly known as what? Choices: - chemical poisoning - the flu - viral poisoning - food poisoning A:
food poisoning

Answer the following question given this paragraph: When an atomic nucleus decays, it does so by releasing one or more particles. The atom often (but not always) turns into a different element during the decay process. The amount of radiation given off by a certain sample of radioactive material depends on the amount of material, how quickly it decays, and the nature of the decay product. Big, rapidly decaying samples are most dangerous. Q: The atom often (but not always) turns into a different what during the decay process? Choices: - concept - reaction - aspect - element A:
element

Answer the following question given this paragraph: Compliance Compliance is the ability of any compartment to expand to accommodate increased content. A metal pipe, for example, is not compliant, whereas a balloon is. The greater the compliance of an artery, the more effectively it is able to expand to accommodate surges in blood flow without increased resistance or blood pressure. Veins are more compliant than arteries and can expand to hold more blood. When vascular disease causes stiffening of arteries, compliance is reduced and resistance to blood flow is increased. The result is more turbulence, higher pressure within the vessel, and reduced blood flow. This increases the work of the heart. Q: When vascular disease causes stiffening of arteries, compliance is reduced and resistance to blood flow is increased. the result is more turbulence, higher pressure within the vessel, and reduced blood flow. this increases the work of this? Choices: - lung - brain - muscles - heart A:
heart
