What is the function of the respiratory system?

• Exchange of oxygen and carbon dioxide

• Regulation of body temperature

• Transport of nutrients

What is the difference between mitosis and meiosis?

• The difference is in the timing of cell division

• The main difference between mitosis and meiosis is the number of daughter cells produced and the number of chromosomes in each daughter cell.

• Mitosis occurs in somatic cells, while meiosis occurs in gametes

• Mitosis produces genetically identical daughter cells, while meiosis produces genetically diverse daughter cells
