◦
9.9 s

◦
7.8 s

◦
8.5 s

◦
9.2 s

◦
6.4 s


Question 2

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
