Answer the following question given this paragraph: The name silicon is derived from the Latin word for flint, silex. The metalloid silicon readily forms compounds containing Si-O-Si bonds, which are of prime importance in the mineral world. This bonding capability is in contrast to the nonmetal carbon, whose ability to form carbon-carbon bonds gives it prime importance in the plant and animal worlds. Q: The name silicon is derived from the latin word for flint? Choices: - silk - simple - pelea - silex A:
silex

Answer the following question given this paragraph: Only certain types of base pairing are allowed. For example, a certain purine can only pair with a certain pyrimidine. This means A can pair with T, and G can pair with C, as shown in Figure 3.33. This is known as the base complementary rule. In other words, the DNA strands are complementary to each other. If the sequence of one strand is AATTGGCC, the complementary strand would have the sequence TTAACCGG. During DNA replication, each strand is copied, resulting in a daughter DNA double helix containing one parental DNA strand and a newly synthesized strand. Q: A, t, g, and c pairs are associated with what substance that is important in genetics? Choices: - plasma - bacteria - blood - dna A:
dna

Answer the following question given this paragraph: The entropy change is positive as the solid state changes into the liquid state. If the transition went from the liquid to the solid state, the numerical value for would be the same, but the sign would be reversed since we are going from a less ordered to a more ordered situation. Q: The entropy change is positive as the solid state changes into which state? Choices: - mixture - gas - chemical - liquid A:
liquid
