Answer:
E. bind to troponin which moves the tropomyosin
Explanation:
calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction
Answer: DNA provides a set of chemical instructions to specific genes that the gene uses to make proteins in order to determine traits.
Explanation: Genes provide instructions that are used to determine the sequence of amino acids needed to make up a protein.
Answer:
True
