Give an example of a polar molecule?
water
Why is your hair flexible?
Because of the oil
Where are your sweat glands located?
dermis
What is it when epidermal cells that are at the surface flake off and clump together they make?
dandruff
If you have more melanin - - you need (more or less) exposure to the sun to get vitamin D?
more
What is NOT caused from sun burns and tanning? wrinkles thickening of the epidermis increased cell division skin blisters
increased cell division
Be able to draw and label the parts of a water molecule.
