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.
Answer:

Explanation:
Answer:
The ocean takes in that carbon, as a result, the ocean becomes more acidic which has many negative effects on ocean life.
The target heart rate zone for moderate-intensity aerobic exercise is based on the maximum heart rate which varies with age (decrease with aging). Estimating maximum heart rate can be done by subtracting the age number from 220. So, in this case: 220-32=188
Curtis’ estimated maximum heart rate is 188 beats per minute.
Geographical variation refers to differences among populations in genetically based traits across the natural geographic range of a species. ... In the simplest case, we divide these factors into purely genetic versus environmental components to tease apart their relative contributions to observed phenotypic variation.
