Question

most bacteria increase their numbers by
multiple choice
○ hyphae formation.
○ binary fission.
○ endocytosis.
○ sexual reproduction.

Explanation:

To determine how most bacteria increase their numbers, we analyze each option:

• Hyphae formation is associated with fungi (like molds), not bacteria.
• Binary fission is the primary asexual reproduction method for prokaryotes (including most bacteria), where a single cell divides into two identical daughter cells.
• Endocytosis is a process by which cells take in substances, not a reproductive method for bacteria.
• Most bacteria reproduce asexually, and sexual reproduction (in the traditional sense) is rare; they mainly use methods like binary fission.

Answer:

B. binary fission
