Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

The correct answer is - A and B.
The nuclear energy can been seen at either way, and that is why it has both its supporters and its critics.
The nuclear energy is cheaper, cleaner, and nuclear centrals can produce much more and much more efficiently as well, so it can easily be seen why it can be extremely useful in a world where the energy demand is ever-growing.
On the other side, there's a huge risk with the nuclear centrals because if there's some problem, it can all turn into a catastrophe that will affect huge area. The consequences of a nuclear reactor exploding or leaking are long term, and takes lot of time that the area can be used for anything. Lots of human lives can be lost, and affected for numerous generations, as well as destroying the natural environment in a brutal way.

They refer to one species or individual.

Explanation:
In the body, water moves through semi-permeable membranes of cells and from one compartment of the body to another by a process called osmosis. Osmosis is basically the diffusion of water from regions of higher concentration to regions of lower concentration, along an osmotic gradient across a semi-permeable membrane.
To proceed scientifically, you could measure several properties of the unknown liquid and compare them with the properties of known substances. You might observe and measure such properties as color, odor, texture, density, boiling point, and freezing point.
