true false
during cytokinesis in animal cells, a new plasma membrane and cell wall form
cell division in prokaryotes is called mitosis
in eukaryoties, he nucleus and cytoplasm divide at the same time
an \x\ shaped chromosome is made from two identical chromatids
interphase is the longest portion of the cell cycle
meiosis has 8 phases
in human a human egg & sperm, they each have 23 chromosomes

<reasoning>

Analyze statements 1 to 3

• Statement 1: Animal cells do not form a cell wall during cytokinesis; they form a cleavage furrow. (False)
• Statement 2: Prokaryotic cell division is called binary fission, not mitosis. (False)
• Statement 3: In eukaryotes, karyokinesis (nuclear division) and cytokinesis (cytoplasmic division) occur sequentially, not at the same time. (False)

Analyze statements 4 to 5

• Statement 4: A duplicated "X"-shaped chromosome consists of two identical sister chromatids joined at the centromere. (True)
• Statement 5: Interphase (consisting of G1, S, and G2 phases) accounts for approximately 90% of the cell cycle's duration. (True)

Analyze statements 6 to 7

• Statement 6: Meiosis consists of two successive nuclear divisions (Meiosis I and Meiosis II), each containing 4 main stages (prophase, metaphase, anaphase, telophase), totaling 8 phases. (True)
• Statement 7: Human gametes (egg and sperm) are haploid cells containing 23 chromosomes. (True)
