Q: Answer the following question given this paragraph: where k is a constant equal to Electric Potential. Q: What radiation, generally produced by thermal motion and the vibration and rotation of atoms and molecules, literally means "below red"? Choices: - microscopic - ultraviolet - gamma radiation - infrared A:
A: infrared

Q: Answer the following question given this paragraph: When geologic and climatic conditions are changing, evolution may occur more quickly. Thus, long periods of little change may be interrupted by bursts of rapid change. This model of the timing of evolution is called punctuated equilibrium . It is better supported by the fossil record than is gradualism. Q: Fossil records support the idea that periods of little change may be interrupted by bursts of rapid change, an evolutionary model contrasted by what? Choices: - elitism - darwinian - minimalism - gradualism A:
A: gradualism

Q: Answer the following question given this paragraph: The smallest and lightest alcohols (methanol, ethanol, propanol) are completely soluble in water in all proportions. In a solution, the hydroxyl groups of alcohol molecules and the water molecules form hydrogen bonds with each other, resulting in complete miscibility. However, as the length of the carbon chain increases, the solubility decreases. The solubility of 1-butanol is 7.4 g per 100 g of water, while that of 1-pentanol is 2.7 g per 100 g water, and 1-octanol is 0.06 g per 100 g water. The carbon chain portion of the larger alcohol molecule is nonpolar and leads to the decreased solubility of the overall compound. Q: The smallest and lightest alcohols (methanol, ethanol, propanol) are completely soluble in? Choices: - gasoline - oil - argon - water A:
A: water

Q: Answer the following question given this paragraph: Q: In many polychaetes, the parapodia are richly supplied with blood vessels and also function as what? Choices: - tails - pores - scales - gills A:
A: gills
