In which of the following ways is dna replication similar to transcription?
a) new cells are created after both have happened.
b) cytosine pairs with guanine in both.
c) both take place in the cell cytoplasm.

B) Cytosine pairs with guanine in both.

Explanation:

DNA replication is the process by which DNA makes an identical  copy of itself during cell division. In this process the DNA polymerase adds a new strand of DNA to the template strand by matching Cytosines with Guanines and Adenines with Thymines.

In transcription  a copy of a specific DNA fragment is made,  however, this copy has  Adenines paired with Uracils instead Adenines  with Thymines.

In both, replication and transcription Cytosine pairs with guanine.

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
