Answer the following question given this paragraph: Pressure is given in units of millimeters of mercury. We can either convert this to atmospheres or use the value of the ideal gas constant that includes the mmHg unit. We will take the second option. Substituting into the ideal gas law,. Q: What property of certain states of matter can be given in units of millimeters of mercury? Choices: - solvency - gravity - velocity - pressure A:
pressure
Answer the following question given this paragraph: Roundworms may be free-living or parasitic organisms. Free-living worms are found mainly in freshwater habitats. Some live in moist soil. They generally feed on bacteria, fungi, protozoa, or decaying organic matter. By breaking down organic matter, they play an important role in the carbon cycle. Q: By breaking down organic matter, roundworms play an important role in which cycle? Choices: - water cycle - metamorphic cycle - circadian cycle - carbon cycle A:
carbon cycle
Q: Answer the following question given this paragraph: Most prokaryotes have a peptidoglycan cell wall and many have a polysaccharide capsule (Figure 4.5). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion. Pili are used to exchange genetic material during a type of reproduction called conjugation. Fimbriae are used by bacteria to attach to a host cell. Q: The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents what? Choices: - extinction - exhaustion - Respiration - dehydration A:
A: dehydration
Question: Answer the following question given this paragraph: The formation of scientific theories is generally guided by the law of parsimony. The word parsimony means "thriftiness. " The law of parsimony states that, when choosing between competing theories, you should select the theory that makes the fewest assumptions. In other words, the simpler theory is more likely to be correct. For example, you probably know that Earth and the other planets of our solar system orbit around the sun. But several centuries ago, it was believed that Earth is at the center of the solar system and the other planets orbit around Earth. While it is possible to explain the movement of planets according to this theory, the explanation is unnecessarily complex. Q: What the scientific concept stating that when looking at two competing theories, the one with fewer assumptions should be chosen? Choices: - law of thermodynamics - law of simplicity - law of averages - law of parsimony A:
Answer: law of parsimony

Answer the following question given this paragraph: Echinoderms are marine organisms that make up the phylum Echinodermata. They can be found in the ocean from the equator to the poles. There are roughly 6000 living species of echinoderms. They are among the most distinctive organisms within the animal kingdom. Members of the phylum include sea stars (starfish), sand dollars, and feather stars, shown in Figure below . See "Different But Equal" at http://www. pbs. org/kcet/shapeoflife/episodes/ultimate. html for an introduction to echinoderms. Q: Echinoderms have what type of body symmetry? Choices: - Translational symmetry - Rotational symmetry - Reflectional symmetry - radial symmetry A:
**Answer**
radial symmetry
