Bacteria use conjugation as a form of
A
nitrogen fixation
B
sexual reproduction
C
asexual reproduction
D
metabolism
Explanation: 

Detailed explanation-1: -Conjugation is a form of sexual reproduction in bacteria. Two individual cells are united by a tube formed by outgrowths from one or both cells. Genetic material from one cell (designated the male) then passes through the tube to unite with genetic material in the other cell (designated female).

Detailed explanation-2: -Conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. Conjugation as a mode of sexual reproduction is seen in bacteria and some ciliated protozoa.

Detailed explanation-3: -conjugation is considered a sexual process because it involves the horizontal transfer of genetic material, and is often integrated into the recipient genome via homologous recombination.

Detailed explanation-4: -Conjugation occurs when two bacteria-a donor and a recipient-sidle up to each other. The donor creates a tube, called a pilus, that attaches to the recipient and pulls the two cells together. A plasmid from the donor passes to the recipient, providing the recipient with new genetic information.
