50.
Yeast reproduce:
Correct Answer
B. By budding
Explanation
Yeast reproduce by budding, which is a form of asexual reproduction. In budding, a small bud forms on the parent yeast cell, grows in size, and eventually separates to become a new individual yeast cell. This process allows yeast to rapidly increase their population size. Conjugation, on the other hand, is a form of sexual reproduction that involves the exchange of genetic material between two yeast cells. Fission refers to the splitting of a cell into two separate cells, which is not a method of reproduction for yeast.
