Answer the following question given this paragraph: Condensation changes water vapor to liquid water. As air rises higher into the atmosphere, it cools. Cool air can hold less water vapor than warm air. So some of the water vapor condenses into water droplets. Water droplets may form clouds. Q: What changes water vapor to liquid water? Choices: - fermentation - global warming - combustion - condensation A:
condensation

Answer the following question given this paragraph: Arteries are muscular blood vessels that carry blood away from the heart. They have thick walls that can withstand the pressure of blood being pumped by the heart. Arteries generally carry oxygen-rich blood. The largest artery is the aorta, which receives blood directly from the heart. Q: What type of blood vessels carry blood away from the heart? Choices: - Heart - tubes - Viens - arteries A:
(Answer)
arteries
Ques: Answer the following question given this paragraph: The methane and ammonia examples illustrate the connection between orbital hybridization and the VSEPR model. The electron domain geometry predicted by VSEPR leads directly to the type of hybrid orbitals that must be formed to accommodate that geometry. Both methane and ammonia have tetrahedral electron domain geometries and thus both undergo sp 3 hybridization. Q: What type of hybridization does ammonia undergo? Choices: - h2O hybridization - ionic hybridization - nh3 hybridization - sp 3 hybridization A:
Ans: sp 3 hybridization
(Q).
Answer the following question given this paragraph: Q: In biological augmentation, ecologists use what to add essential materials to ecosystems? Choices: - sediments - fluids - stem cells - organisms A:
(A).
organisms
Ques:Answer the following question given this paragraph: Ocean water also absorbs gases from the atmosphere. The most important are oxygen and carbon dioxide. Oxygen is needed by living things in the oceans. Much of the carbon dioxide sinks to the bottom of the seas. Carbon dioxide is a major cause of global warming. By absorbing carbon dioxide, the oceans help control global warming. Q: How do oceans help control global warming? Choices: - releasing oxygen - reflecting light - Cooling air - absorbing carbon dioxide A:

Ans:absorbing carbon dioxide
Answer the following question given this paragraph: Arthropods have a life cycle with sexual reproduction. Most species go through larval stages after hatching. The larvae are very different from the adults. They change into the adult form in a process called metamorphosis . This may take place within a cocoon. A familiar example of metamorphosis is the transformation of a caterpillar (larva) into a butterfly (adult). Other arthropod species, in contrast, hatch young that look like small adults. These species lack both larval stages and metamorphosis. Q: Arthropods change into the adult form in a process called what? Choices: - parthenogenesis - spontaneous mutation - budding - metamorphosis A:
metamorphosis
