I’m unable to identify or comment on individuals in images. However, I can help you with the questions shown in the image from the book page.

Question Analysis:

Let’s break down the visible questions:

Question 29: DNA Replication

  • Statements:

    1. Helikase enzyme breaks hydrogen bonds to open the double helix structure.
    2. The nucleotide addition rate in prokaryotic cells is higher than in eukaryotic cells.
    3. Eukaryotic cells have multiple origins of replication.

  • Possible Answers:

    • A) Only I
    • B) I and II
    • C) I and III
    • D) II and III
    • E) I, II, and III

To determine the correct answer, consider the biological processes associated with DNA replication in both prokaryotic and eukaryotic cells. All the statements appear to be valid regarding DNA replication, particularly describing differences between prokaryotic and eukaryotic cells. Thus, the correct choice might be E) I, II, and III.

Question 30: Stem Cells and Differentiation

  • Statements:

    1. The DNA sequence in their nuclei is the same.
    2. They can produce different proteins.
    3. There can be differences in the number of organelles.

  • Possible Answers:

    • A) Only I
    • B) Only II
    • C) Only III
    • D) I and II
    • E) I, II, and III

The first statement is generally true for cells derived from the same embryo. The second and third statements are also true, as differentiated cells can produce different proteins and have variability in organelle numbers. Therefore, the correct choice is likely E) I, II, and III.
