DNA is a nucleic acid molecule that undergoes a replication process to form a new daughter strand. The blue segment is the parental strand, and the yellow is the daughter strand.

<h3>What is replication?</h3>

Replication is the process of the central dogma that duplicates the copy of the parent strand into new daughter strands. The two helixes of the parent strand get separated to make the complimentary copy of the new strand.

The daughter DNA is semi-conservative and are complementary structure made from the duplication of the parent strand with the help of the replication enzymes.

Therefore, the daughter strands are the semi-conservative copies of the parental strand.

List two ways that a fuel cell differs from an ordinary battery
Alecsey [184]

The simple answer is that in a battery the chemical reactions that produce the electrical current are produced from materials that are already in the battery itself, whereas in a fuel cell, the reactants, almost always Hydrogen and Oxygen are fed to the cell like an external fuel.

. However, while a battery makes electricity from the energy it has stored inside the battery, a fuel cell makes its electricity from fuel in an external fuel tank This means that while a battery may run dead, a fuel cell will make electricity as long as fuel is supplied. For hydrogen fuel cells, hydrogen is the fuel and it's stored in a tank connected to the fuel cell. When hydrogen in the tank runs low, you refill it, or replace it with a full tank.
