Answer is False took biology last year lol
Answer:
Tropomyosin is pulled away from the myosin-binding site on actin.
Explanation:
Actin and myosin are contractile proteins present in muscle cells. They interact with each other to cause muscle contraction.
When calcium binds to troponin protein, confirmational changes occur in troponin. It pulls tropomyosin away from myosin binding sites on actin. The sites become free and cross bridge is formed between myosin and actin which leads to muscle contraction. The process continues until no more calcium and ATP is available after which tropomyosin again covers the binding sites on actin.
Answer: A. It conducts heat well.
Explanation:
Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature.
