The answer is Protein. T<span>he primary type of macromolecule in the actin and myosin that make up muscle cells is Protein. </span>Muscles<span> are composed of two major protein filaments: a thick filament composed of the protein </span>myosin<span> and a thin filament composed of the protein </span>actin<span>. </span>Muscle contraction<span> occurs when these filaments slide over one another in a series of repetitive events.</span>
I believe that the method that is the most effective way to quit smoking is to use a nicotine patch. What the nicotine patch does is reduce the amount of nicotine entering your body. Gradually, you decrease the amounts you are taking each day until you finally get rid of the nicotine entirely. The nicotine patch still gives you the effects of nicotine, but without the negative effects of smoking.
Answer: first statement that Keratin is a protein in the cells of the epidermis that provides strength and waterproofing is correct
Explanation:
The outer layer of skin, the epidermis, provides waterproofing and serves as a barrier to infection.
The middle layer of skin, the dermis, contains blood vessels, nerves, and glands that are important for our skin’s function. The inner layer of the skin, the subcutis, contains fat that protects us from trauma. The cells in all of the layers except the stratum basale are called keratinocytes. A keratinocyte is a cell that manufactures and stores the protein keratin. Keratin is an intracellular fibrous protein that gives hair, nails, and skin their hardness and water-resistant properties.
Keratin is an important protein in the epidermis. Keratin has two main functions: to adhere cells to each other and to form a protective layer on the outside of the skin. In epithelial cells, keratin proteins inside the cell attach to proteins called desmosomes on the surface.
