The outer layer of the skin is called the _(1)_ and it is composed of two layers. The top layer where mitosis no longer occurs is made up of _(2)_ cells. The second layer where mitosis occurs is called the _(3)_ layer. The basal layer has two important proteins _(4)_ & _(5)_ made by specialized cells. The second layer of skin is called the_(6)_. In this layer you can find _(7)_ that help maintain a constant body temperature. When they contract heat is _(8)_ and when they dilate heat is_(9)_. Also in this layer you can find _(10)_ that consists of dead cells filled with _(11)_ (a protein). These things go through _(12)_ in order to grow. _(13)_ also goes through mitosis to grow and helps _(14)_ fingertips and toetips. _(15)_ help detect pain and heat in the skin. The last layer is called the _(16)_ that stores _(17)_.
a. Collagen
b. Elastin
c. Keratin
d. Melanin
e. Oil gland
f. Sweat gland
g.
The outer layer of the bone is called the _(24)_ that has nerves and blood vessels that pass through it to the next layer called the _(25)_ bone.
