問 2
1 点When a human body cell undergoes mitosis and a reproductive cell undergoes meiosis, the resulting daughter cells differ significantly. Which statement correctly compares the genetic outcome of these two processes?
問 3
1 点During the process of meiosis in human reproductive organs, how many gametes are produced from one original cell and what is their chromosome count?
問 4
1 点A single human body cell undergoes mitosis during growth. Later, a cell in the reproductive organs undergoes meiosis to produce gametes.
Compare the final number of chromosomes and the genetic relationship of the daughter cells to the original parent cell for both processes.
問 5
1 点A human body cell undergoes mitosis to produce replacement cells, while cells in reproductive organs undergo meiosis to form gametes. Which statement correctly compares the chromosomal outcome of these two processes?
問 6
2 点State two reasons why body cells undergo mitosis in a mature human.

問 9
5 点Cell division occurs through two distinct processes: mitosis and meiosis.
a) State exactly where in the human body meiosis occurs.
b) Compare a cell produced by mitosis with a cell produced by meiosis in terms of the number of chromosomes and genetic similarity to the parent cell.
c) Explain why it is biologically important that gametes are produced by meiosis rather than mitosis for the survival of the species through generations.
