17. the enzyme dna polymerase works only in the 5' to 3' direction. how does this affect the leading strand and the lagging strand? o a. dna polymerase can use only the leading strand as a template. a different enzyme is used to synthesize dna on the lagging strand o b. dna polymerase can work on both the leading and the lagging strand but is much faster on the leading strand o c. dna polymerase can work continuously on the leading strand but must flip the lagging strand around before it can work on it o d. dna polymerase can work continuously on the leading strand but works discontinuously on the lagging strand, creating okazaki fragments.

Which statement best describes how the loudness of the sound affects the high-pressure region created by the sound wave? a. a louder sound has no effect on the pressure created. b. a louder sound means a high-pressure region that is higher. c. a louder sound means a high-pressure region that is not as high.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.

Which of these transport mechanisms moves glucose from the blood into a cell? active transport diffusion facilitated diffusion osmosis
