Answer the following question given this paragraph: Q: Glucose, fructose, and other sugars that have six carbons are called what? Choices: - alcohols - fluxes - catalysts - hexoses A:
hexoses
(Question)
Answer the following question given this paragraph: Q: Winds are caused by differences in what? Choices: - elevation - temperature - water pressure - air pressure A:
(Answer)
air pressure
Ques: Answer the following question given this paragraph: The higher up a food chain that humans eat, the greater the levels of toxic metals they take in. That's why people should avoid eating too much of large fish such as tuna. Tuna are predators near the top of their food chains. They have been shown to contain high levels of mercury. In people, heavy metals can damage the brain and other organs. Unborn babies and young children are most affected. That's because their organs are still developing. Q: Tuna have been shown to contain high levels of what metal? Choices: - cadmium - titanium - iron - mercury A:
Ans: mercury
(Q).
Answer the following question given this paragraph: Mercury manometers are often used to measure arterial blood pressure. An inflatable cuff is placed on the upper arm as shown in Figure 11.17. By squeezing the bulb, the person making the measurement exerts pressure, which is transmitted undiminished. Q: What are mercury manometers often used to measure? Choices: - weight - balance - brain waves - blood pressure A:
(A).
blood pressure
Ques:Answer the following question given this paragraph: Although migration is thought of as innate behavior, only some migrating species always migrate (obligate migration). Animals that exhibit facultative migration can choose to migrate or not. Additionally, in some animals, only a portion of the population migrates, whereas the rest does not migrate (incomplete migration). For example, owls that live in the tundra may migrate in years when their food source, small rodents, is relatively scarce, but not migrate during the years when rodents are plentiful. Foraging Foraging is the act of searching for and exploiting food resources. Feeding behaviors that maximize energy gain and minimize energy expenditure are called optimal foraging behaviors, and these are favored by natural section. The painted stork, for example, uses its long beak to search the bottom of a freshwater marshland for crabs and other food (Figure 45.36). Q: When a species always migrates, what is this type of migration called? Choices: - emigration - genus migration - mass migration - obligate migration A:

Ans:obligate migration
Answer the following question given this paragraph: Electrons at the outermost energy level of an atom are called valence electrons. They determine many of the properties of an element. That's because these electrons are involved in chemical reactions with other atoms. Atoms may share or transfer valence electrons. Shared electrons bind atoms together to form chemical compounds. Q: What are electrons at the outermost energy level of an atom are called? Choices: - core electrons - ions - shell electrons - valence electrons A:
valence electrons
