Answer the following question given this paragraph: Figure 22.24 The Van Allen radiation belts are two regions in which energetic charged particles are trapped in the Earth's magnetic field. One belt lies about 300 km above the Earth's surface, the other about 16,000 km. Charged particles in these belts migrate along magnetic field lines and are partially reflected away from the poles by the stronger fields there. The charged particles that enter the atmosphere are replenished by the Sun and sources in deep outer space. Q: The van allen radiation belts are two regions in which energetic charged particles are trapped in earth's what? Choices: - gravitational field - cloud cover - ionosphere - magnetic field A:
magnetic field

lateral line system
Ques: Answer the following question given this paragraph: Q: The hypothalamic releasing and inhibiting hormones are secreted near capillaries at the base of the what? Choices: - lungs - hippocampus - pancreas - hypothalamus A:
Ans: hypothalamus
(Q).
Answer the following question given this paragraph: Deep sea trenches are found near chains of active volcanoes. These volcanoes can be at the edges of continents or in the oceans. Trenches are the deepest places on Earth. The deepest trench is the Mariana Trench in the southwestern Pacific Ocean. This trench plunges about 11 kilometers (35,840 feet) beneath sea level. The ocean floor does have lots of flat areas. These abyssal plains are like the scientists had predicted. Q: What are the deepest places on earth? Choices: - deep sea diversions - deep sea caves - deep sea resonances - deep sea trenches A:
(A).
deep sea trenches
Ques:Answer the following question given this paragraph: Heterotrophs are organisms incapable of photosynthesis that must therefore obtain energy and carbon from food by consuming other organisms. The Greek roots of the word heterotroph mean "other" (hetero) "feeder" (troph), meaning that their food comes from other organisms. Even if the food organism is another animal, this food traces its origins back to autotrophs and the process of photosynthesis. Humans are heterotrophs, as are all animals. Heterotrophs depend on autotrophs, either directly or indirectly. Deer and wolves are heterotrophs. A deer obtains energy by eating plants. A wolf eating a deer obtains energy that originally came from the plants eaten by that deer. The energy in the plant came from photosynthesis, and therefore it is the only autotroph in this example (Figure 5.3). Using this reasoning, all food eaten by humans also links back to autotrophs that carry out photosynthesis. Q: Organisms incapable of photosynthesis that must therefore obtain energy and carbon from food by consuming other organisms are called what? Choices: - photoautotrophs - autotrophs - chemoautotrophs - heterotrophs A:

Ans:heterotrophs
Answer the following question given this paragraph: Polymers are long molecules composed of chains of units called monomers. Q: What long molecules are composed of chains of units called monomers? Choices: - complexes - microbes - drummers - polymers A:
