Answer the following question given this paragraph: Habitats Nearly all protists exist in some type of aquatic environment, including freshwater and marine environments, damp soil, and even snow. Several protist species are parasites that infect animals or plants. A few protist species live on dead organisms or their wastes, and contribute to their decay. Q: Nearly all protists exist in some type of aquatic environment, including freshwater and marine environments, damp soil, and even snow. several protist species are parasites that infect animals or plants. a few protist species live on dead organisms or their wastes, and contribute to what? Choices: - greenhouse gas - habitat loss - spontaneous mutation - their decay A:
their decay

Answer the following question given this paragraph: Sending humans to the seafloor is expensive and dangerous. Having to return humans safely to the surface limits what a mission can do. Remotely operated vehicles , or ROVs, allow scientists to study the deep without going to the seafloor. These small vehicles carry cameras and scientific instruments. ROVs were used to study inside the Titanic . This would have been far too dangerous for a manned sub to enter. Scientists control ROVs electronically with sophisticated operating systems. Q: What do scientists use to study the deep without going to the seafloor? Choices: - drill rigs - telescopes - ultrasound machines - remotely operated vehicles A:
remotely operated vehicles

Answer the following question given this paragraph: Greenhouse gases trap heat in the atmosphere. These gases include carbon dioxide, methane, water vapor, and ozone. Q: Which gases trap heat in the atmosphere? Choices: - fluorine and nitrogen - methane and helium - ozone - greenhouse A:
greenhouse

Answer the following question given this paragraph: Global winds occur in belts around the globe. They are caused by unequal heating of Earth's surface. The Coriolis effect causes global winds to blow on a diagonal over the surface. Unequal heating also causes jet streams high in the troposphere. Q: What effect causes global winds to blow on a diagonal over the earth's surface? Choices: - dopler effect - resonant effect - centrifugal effect - coriolis effect A:
coriolis effect
