The correct answer is A. Binary Fission.
Binary fission is a type of asexual reproduction in which a single cell divides into two identical daughter cells. It is the most common form of reproduction in bacteria.
In binary fission, the cell first replicates its DNA. The cell then divides into two equal halves, each with its own copy of the DNA. The two daughter cells are genetically identical to the parent cell.
Binary fission is a very efficient way to reproduce. It allows bacteria to quickly increase in number. This is important for bacteria, as they are constantly facing threats from predators and the environment.
B. Spirilla is a type of bacteria that has a spiral shape. Spirilla are found in both fresh and salt water. They can be pathogenic, meaning that they can cause disease in humans.
C. RNA is a type of nucleic acid. It is found in all living cells. RNA is involved in the process of protein synthesis.
D. Fusion is a type of sexual reproduction in which two cells combine to form a new cell. Fusion is not a common form of reproduction in bacteria.
