Analyze the first question

The first question asks: "What is the evidence for this unit?"
The options discuss matter, observing cell division, the cell cycle with checkpoints, and bacterial cell division.
To provide evidence for a unit on cell division and the cell cycle, the direct observation of cells undergoing division serves as physical, empirical evidence.
Therefore, "You can physically see the cells dividing" is the most direct empirical evidence supporting the study of cell division.

Analyze the second question

The second question asks: "What is this image demonstrating?"
Let's trace the diagram:

• It starts with a diploid cell \(A\) containing homologous chromosomes.
• The chromosomes replicate and align.
• At stage \(B\), homologous chromosomes pair up and then separate during the first division into two haploid cells at stage \(C\).
• At stage \(D\), sister chromatids separate, resulting in four haploid daughter cells, each containing a single set of chromosomes.

This process of producing four genetically diverse haploid cells from one diploid cell is Meiosis.
We can connect this to the student's mastered concepts of Meiosis and Cell Division.
