Answer the following question given this paragraph: Summary A suspension is a heterogeneous mixture of particles of one substance distributed throughout a second phase; the dispersed particles separate from the dispersing phase on standing. In contrast, the particles in a colloid are smaller and do not separate on standing. A colloid can be classified as a sol, a dispersion of solid particles in a liquid or solid; a gel, a semisolid sol in which all of the liquid phase has been absorbed by the solid particles; an aerosol, a dispersion of solid or liquid particles in a gas; or an emulsion, a dispersion of one liquid phase in another. A colloid can be distinguished from a true solution by its ability to scatter a beam of light, known as the Tyndall effect. Hydrophilic colloids contain an outer shell of groups that interact favorably with water, whereas hydrophobic colloids have an outer surface with little affinity for water. Emulsions are prepared by dispersing a hydrophobic liquid in water. In the absence of a dispersed hydrophobic liquid phase, solutions of detergents in water form organized spherical aggregates calledmicelles. Phospholipids are a class of detergent-like molecules that have two Saylor URL: http://www. saylor. org/books.

Q: Answer the following question given this paragraph: Note the word science in that last sentence. Earth Science is a science, or maybe it's made up of a lot of sciences. But what is science? Most people think of science as a bunch of knowledge. And it is. But science is also a way of knowing things. It's different from other ways of knowing because it is based on a method that relies on observations and data. Science can't say how many angels can dance on the end of a pin because that question can't be tested. In fact, science can't even say if there are such things as angels for the same reason. For something to be science, it must be testable. And scientists are the people who do those tests. Q: A fact or question is only considered science if it has what property? A:
Answer: it is testable

Problem:OPTIONS:
- entomology
- methodology
- physiology
- taxonomy

Answer the following question given this paragraph: All living things need water. For most human uses, water must be fresh. Of all the water on Earth, only 1 percent is fresh, liquid water. Most of the rest of Earth's water is either salt water in the ocean or ice in glaciers and ice caps. Q: Although humans require it, what accounts for just one percent of all water on earth? A:
OPTIONS:
- snow
- salt water
- glaciers
- fresh water

Answer: fresh water
