• Melon

• Melanin

• Epidermis

Identify the statement that would is INCORRECT regarding Melanin & skin color:

• Those with more Melanin have darker skin.

• Certain ethnicities have darker skin.

• People with less Melanin are less likely to have skin cancer.

• Protection from UV rays are more prominent in those with less Melanin.

Identify the reason(s) for cells to produce Melanin:

• Hair, skin & eye color is a result on the amount of Melanin in humans & animals.

• Melanocytes in the body produce Melanin to protect the skin from sun damage.
