Q: Answer the following question given this paragraph: This odd-looking creature is a fish called a puffer fish. Like all fish, puffer fish are vertebrates. The puffer fish puffs up by rapidly filling its stretchy stomach with water. The reason? Getting bigger makes the fish seem larger to potential predators. Just to be on the safe side, the puffer fish also produces venom. In fact, it's the second-most-poisonous vertebrate in the world after the poison dart frog. In this chapter, you'll learn more about vertebrates such as these. You'll find out that vertebrates are a diverse and fascinating group of animals. Q: What do puffer fish produce to protect itself? Choices: - teeth - enzymes - hormones - venom A:
A: venom

Q: Answer the following question given this paragraph: Organic chemistry is the study of the chemistry of carbon compounds. Q: Organic chemistry is the study of the chemistry of what? Choices: - hydrogen - metals - oxidation - carbon compounds A:
A: carbon compounds

Q: Answer the following question given this paragraph: in which C is a constant that depends on the type of crystal structure; Z+ and Z are the charges on the ions; and Ro is the interionic distance (the sum of the radii of the positive and negative ions). Thus, the lattice energy of an ionic crystal increases rapidly as the charges of the ions increase and the sizes of the ions decrease. When all other parameters are kept constant, doubling the charge of both the cation and anion quadruples the lattice energy. For example, the lattice energy of LiF (Z+ and Z = 1) is 1023 kJ/mol, whereas that of MgO (Z+ and Z = 2) is 3900 kJ/ mol (Ro is nearly the sameabout 200 pm for both compounds). Different interatomic distances produce different lattice energies. For example, we can compare the lattice energy of MgF2 (2957 kJ/mol) to that of MgI2 (2327 kJ/mol) to observe the effect on lattice energy of the smaller ionic size of F as compared to I. Q: Different interatomic distances produce different lattice what? Choices: - qualities - surfaces - weights - energies A:
A: energies

Q: Answer the following question given this paragraph: Photosynthesis changes light energy to chemical energy. The chemical energy is stored in the bonds of glucose molecules. Glucose is used for energy by the cells of almost all living things. Plants make their own glucose. Other organisms get glucose by consuming plants (or organisms that consume plants). How do living things get energy from glucose? The answer is cellular respiration. Q: Photosynthesis changes light energy to what type of energy? Choices: - radiation - potential - solar - chemical A:
A: chemical
