• Cell differentiation
• Apoptosis
Mitosis i
Binary fission

Answer 1

1) 46 chromosomes — each child has 46 (diploid human chromosome number).
2) Prokaryotic cells lack membrane-bound organelles, whereas eukaryotic cells have membrane-bound organelles. (Correct statement.)
3) Bacteria — they divide by binary fission, not mitosis.
4) Cell differentiation — the process that produces specialized cell types.
