Answer the following question given this paragraph: Scientists have built machines called particle accelerators. These amazing tools smash particles that are smaller than atoms into each other head-on. This creates new particles. Scientists use particle accelerators to learn about nuclear fusion in stars. They can also learn about how atoms came together in the early universe. Two well-known accelerators are SLAC, in California, and CERN, in Switzerland. Q: What amazing machines smash particles that are smaller than atoms into each other head-on? Choices: - nitrogen accelerators - observant accelerators - absorption accelerators - particle accelerators A:
particle accelerators

Answer the following question given this paragraph: An isotonic solution is a solution in which the amount of dissolved material is equal both inside and outside of the cell. Water still flows in both directions, but an equal amount enters and leaves the cell. Q: In which solution is the amount of dissolved material equal both inside and outside of the cell? Choices: - supersaturated - exothermic - hypotonic - isotonic A:
(Answer)
isotonic
Ques: Answer the following question given this paragraph: Sebaceous glands produce an oily substance called sebum. Sebum is secreted into hair follicles and makes its way to the skin surface. It waterproofs the hair and skin and helps prevent them from drying out. Sebum also has antibacterial properties, so it inhibits the growth of microorganisms on the skin. Q: What kind of oily substance is secreted from sebaceous glands? Choices: - pus - Blood - progesterone - sebum A:
Ans: sebum

Answer the following question given this paragraph: Figure 24.16 Which of the following statements is true? a. A basidium is the fruiting body of a mushroomproducing fungus, and it forms four basidiocarps. The result of the plasmogamy step is four basidiospores. Karyogamy results directly in the formation of mycelia. A basidiocarp is the fruiting body of a mushroom-producing fungus. Figure 24.20 If symbiotic fungi are absent from the soil, what impact do you think this would have on plant growth?. Q: A basidium is the fruiting body of a mushroomproducing fungus, and it forms four what? Choices: - schizonts - tunnels - fossiliferous - basidiocarps A:
(A).
basidiocarps
Ques:Answer the following question given this paragraph: There are approximately 7 billion humans on the planet. How long would it take some bacteria to make 7 billion copies of themselves?. Q: What is the approximate population on the earth? Choices: - 9 trillion - 7.3 billion - 41 billion - 7 billion A:

Ans:7 billion
Answer the following question given this paragraph: Pictured below is a typical elliptical galaxy ( Figure below ). As you might have guessed, elliptical galaxies are elliptical, or egg-shaped. The smallest elliptical galaxies are as small as some globular clusters. Giant elliptical galaxies can contain over a trillion stars. Elliptical galaxies are reddish to yellowish in color because they contain mostly old stars. Q: What do you call egg-shaped galaxies, which are reddish to yellowish in color because they contain mostly old stars? Choices: - conical galaxies - irregular galaxies - spiral galaxies - elliptical galaxies A:
elliptical galaxies
