Question: 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? A:
OPTIONS:
- extinction
- exhaustion
- Respiration
- dehydration
Answer: dehydration

input with options: 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? A:
OPTIONS:
- law of thermodynamics
- law of simplicity
- law of averages
- law of parsimony
output: law of parsimony

Q: 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? A:

OPTIONS:
- Translational symmetry
- Rotational symmetry
- Reflectional symmetry
- radial symmetry

A: radial symmetry

input: OPTIONS:
- clamon
- thallus
- endosperm
- coelom Now, answer this question: Answer the following question given this paragraph: Hydrostatic Skeleton A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called the coelom. The organs of the coelom are supported by the aqueous fluid, which also resists external compression. This compartment is under hydrostatic pressure because of the fluid and supports the other organs of the organism. This type of skeletal system is found in soft-bodied animals such as sea anemones, earthworms, Cnidaria, and other invertebrates (Figure 38.2). Q: A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called what? A:
A:
output: coelom

Answer the following question given this paragraph: [PCl 3][Cl 2] (0.135)(0.135) = = 0.021 0.87 [PCl 5] The equilibrium constant calculated from the equilibrium concentrations is equal to the value of Kc given in the problem (when rounded to the proper number of significant figures). Thus, the calculated equilibrium concentrations check. Kc =. Q: Because of their reactivity, we do not find most representative metals as free elements where? A:

OPTIONS:
- in water
- in the atomospher
- underground
- in nature

Answer: in nature

Q: Answer the following question given this paragraph: Heat capacity is the amount of internal energy that the substance can store. A large heat capacitance means the substance can store a lot of internal energy and thus the temperature changes slowly. Aluminum foil has a small heat capacitance and water has a large one. Q: What is the term for the amount of internal energy that the substance can store? A:

OPTIONS:
- mass capacity
- temperature capacity
- humidity capacity
- heat capacity

A:
heat capacity
