Item RH039002: When a muscle cell of a chimpanzee divides, the new muscle cells contain the same number of chromosomes as the original muscle cell.

Which diagram shows what happens to the number of chromosomes in the muscle cells of a chimpanzee when a single muscle cell divides to form two muscle cells?

  1. Diagram 1 shows what happens to the number of chromosomes in the muscle cells of a chimpanzee when one muscle cell divides to form two muscle cells.
  2. Diagram 2 shows what happens to the number of chromosomes in the muscle cells of a chimpanzee when one muscle cell divides to form two muscle cells.
  3. Diagram 1 shows what happens to the number of chromosomes in the muscle cells of a chimpanzee and Diagram 2 shows what happens to the number of chromosomes when all the other types of cells in the chimp's body divide.
  4. Neither diagram shows what happens to the number of chromosomes of the muscle cells of a chimpanzee when one muscle cell divides to form two muscle cells.
