Identify the process shown in the diagram and select the correct example. The diagram shows a cell elongating and dividing into two daughter cells.

The diagram shows a single cell elongating and then dividing into two roughly equal daughter cells, which then separate. This process is known as binary fission.

• A. Budding in bacteria: Budding involves an outgrowth, not equal division.
• B. Binary fission in amoeba: This is a type of binary fission, which matches the diagram.
• C. Budding in yeast: Yeast reproduces by budding.
• D. Budding in sponge: Sponges reproduce by budding. The process shown is binary fission.

The final answer is $\boxed{\text{B}}$

Gametes are reproductive cells (sperm and egg) that contain half the number
