17. the enzyme dna polymerase works only in the 5' to 3' direction. how does this affect the leadingstrand and the lagging strand? a. dna polymerase can work continuously on the leading strand but must flip the lagging strand aroundbefore it can work on it. b. dna polymerase can use only the leading strand as a template. a different enzyme is used to synthesizedna on the lagging strandc. dna polymerase can work continuously on the leading strand but works discontinuously on the laggingstrand, creating okazaki fragmentsd. dna polymerase can work on both the leading and the lagging strand but is much faster on the leadingstrand

How do adaptation affect a species?

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
