The answer would be 'muscle mass increases'. 

I don't think that's what happens when you get older. 

I hope this helped you.

Brainliest answer would be appreciated. 

Hair turn grey is a chemical change, not a physical change associated with ageing.

What is physical change?

  • "Physical changes alter the appearance of substances but not its chemical content."

What is chemical change?

  • "Chemical change is an irreversible chemical reaction that involves the rearranging of the atoms of one or more substances, resulting in a change in their chemical characteristics or composition and the production of at least one new substance."

What is aging?

  • "Aging is a biological process that begins in early adulthood and continues throughout life."
  • Many physical systems begin to deteriorate progressively throughout early middle age.
  • Fine lines and wrinkles, dry skin, decreased muscle strength, memory loss, and other factors contribute to ageing.
  • Our bones reduces in size and density as we become older. Some people genuinely grow in stature.
  • Due to low bone density, some are more prone to damage. Muscles, tendons, and joints loses their strength and flexibility as a result of this condition. Exercise is an excellent strategy to slow or prevent bone issues.

Hence, the correct answer is: hair turns grey.
