skin's most apical layer is full of keratin
the tight jxn's holding the stratified squamous epithelium together use claudin and occludin
there are a few more cellular jxn's that use other proteins as well
there is type IV collagen laminin and proteoglycans in the basal lamina under the epitheluim
then there is LOTS more collagen in the loose and dense connective tissue underneath.
hope that helps!
This is found in the stratum corneum (horny layer), the most most superficial layer which are dead cells filled with keratin. They form a waterproof barrier and make it tough.
Keratin. Keratin also makes up your nails and hair.
You do not have tough fibrous protein in the epidermis. It is present in the dermis. It is called as collagen fibre.

The organic material in bone is collagen. This is a protein which forms long, flexible fibres in the matrix surrounding the bone cells. It is estimated that collagen makes up 25% of the total protein in the body.
The actual three layers that make up the skin is the Epidermis,Dermis,Subcutaneous. *epidermis is the (outer most) *dermis is the (middle layer) *subcutaneous is the (innermost)
You should look this up it isn't hard to find out. Ribosomes are involved in protein synthesis. Cytoplasm is where you can find the organelles and its where are the chemical fun takes place. The nucleus contains genetic material (DNA) which controls the activities of the cell and the mitochondria is where respiration takes place ATP and all that....this isn't an in depth answer so i think you should look into it more.
Cellulose is hard to digest plant material found in plants such as grass and leaves.Herbivores such as Cows and giraffes can digest cellulose.certain types of bacteria can digest cellulose as well.

The epidermis is tough because it is a dense layer of skin cells held together by keratin, which is a hard protein. The epidermis is the outer layer of the skin.

The flexible protein fibers that make up a sponge are called spongin. The hard, tiny spikes found in sponges are called spicules, and they are made of silica or calcium carbonate.
Adware, like sypware is an evil program that can sneak onto one's hard drive. Apparently, porn material can be found at adware. It's mainly a virus that will infect one's hard drive.
A 4 oz chicken breast has about 20g of protein. One large hard-boiled egg has 6g of protein. So you'd have to eat 3 hard-boiled eggs to get roughly the same amount of protein.
