F. Both regulation and secretion
Explanation:
Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.
The correct answer is this one: "A.When actin filaments are pulled toward the center of the sarcomere, the fiber shortens." The statement that accurately describes the way in which a muscle moves is when actin filaments are pulled toward the center of the sarcomere, the <span>fiber shortens</span>
Function. There, the villi and the microvilli increase intestinal absorptive surface area approximately 30-fold and 600-fold, respectively, providing exceptionally efficient absorption ofnutrients in the lumen. There are alsoenzymes (enterocyte digestive enzyme) on the surface for digestion.
