I would say the 2nd one It helps growth and repair of cells of orgasms
But your school would probably say the 3rd one It helps remove toxins from the body to maintain homeostasis
Explanation:
2. Our cells produce a lot of waste that must be eliminated (excreted) from the body. These residues are called excreta. The residues formed from the chemical reactions that take place inside the cells can be eliminated through:
• of the respiratory system (carbon dioxide)
• skin (sweat)
urinary system (urine)
Our cells expel these substances to maintain the dynamic balance (homeostasis) of our body and promote our well-being.
