How far did the 3 kb band of the dna ladder travel on your gel? the distances will vary a little depending on how long you ran the gel, so pick the distance closest to the one you measured.

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.v

sorry, but you do not have posted the diagram.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
