Most bacteria divide by binary fission, a form of cell division in which DNA replication and segregation occur simultaneously. This process involves active partitioning of the single bacterial chromosome and positioning of the site of septation.

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells.

Binary fission begins when the DNA of the bacterium divides into two replicates. The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. Each daughter cell is a clone of the parent cell.

Mitochondria which is present in both plant and animal cells supplies energy to the cells and hence called as the powerhouse of the cell.

In a concentrated solution there is a large amount of solute.

Aldosterone is a steroid hormone that is produced in the adrenal gland. It is useful and more essential for the conservation of sodium content in the kidney, salivary glands, colon and sweat glands.

Here, Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule is the only option that is NOT correct about aldosterone.
