Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.
From the information given, i can't give you an actual number. But I can tell you that if a rock has a high porosity (its very porous which means that liquids can easily pass through) and has high permeablilty (liquids are able to enter the rock with ease), then groundwater could flow through this rock easily and faster than a rock that has a low porosity and low permeability.
The answer is: “Whales are more efficient at gas exchange than humans which helps them conserve energy.”

When you study about the cladogram of animals you can determine the similarities and difference of each animals in the cladogram. The lizard do share with the chimp or chimpanzee is only lungs so the answer is A. But not only the lizards and chimp do have the lungs but also salamander, pigeon and mouse.
