The correct answer is D. Salt water.
Explanation
The hydrosphere is the system that groups all the waters of the earth that include oceans, seas, rivers, lakes, lagoons, frozen waters like ice and snow, among others. The water of the earth can be classified between salt water and freshwater, within the first group we find the oceans and the seas that represent two thirds of the total water of the earth, that is, 93 percent of the total water of the earth, a figure close to 1 370 323 000km³; the rest of the water is fresh and consists of rivers, lakes, lagoons, streams, groundwater, and glaciers. So, the correct answer is D. Salt water

Answer:
Double-stranded DNA.
Explanation:
Replication may be defined as the process of formation of the daughter DNA from the parent DNA with the help of enzymes and proteins. The three main process of replication are inititation , elongation and termination.
The double stranded DNA molecule undergoes the process of replication. Four different dNTPs - adenine, guanine, thymine and cytosine are required for the process of replication. Primers are required for initiation of the process of replication and ori region is the inititaion point of replication.
Thus, the correct answer is option (a).
