The phosphodiester bonds that lie exactly in the middle of an 8-bp long segment of double-stranded DNA are broken to create two 4-bp long molecules. Phosphodiester bonds between the resulting two double- stranded molecules are then reformed, but withA. 5'-TTAACCGG-3' (on this strand the phosphodiester bond broken is between the A and the C)
B. 5'-AGCTTCGA-3' (on this strand the phosphodiester bond broken is between the T and the adjecent T).
C. 5'-TTCCAAGG-3' (on this strand the phosphodiester bond broken is between the C and the A)
D. 5'-AGCTAGCT-3' (on this strand the phosphodiester bond broken is between the T and the A)

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
