Answer:
The correct answer is -
Actin produces thin contractile filaments within muscle cells,
Myosin produces the dense contractile filaments within muscle cells
Explanation:
Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.
Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.
The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.
<h3>
The lining of the air sacs in the lungs (alveoli) is comprised of what epithelium?</h3>
Simple squamous epithelium contain the air sacs or alveoli of the lungs. This kind of squamous epithelial cells are slightly porous which allows the oxygen from the air to enter the blood in the capillaries of the lung. So the squamous epithelium is the epithelium in which the lining of the air sacs or alveoli occurs. Each alveolus is lined by the squamous epithelium.
So we can conclude that: The epithelium is a type of body tissue that forms the covering on all internal and external surfaces of your body.
