Answer: The correct option is D.
The concentration of calcium in the myofibril must decrease.
Explanation:
This is because calcium makes myosin, actin and ATP to interact which actually lead to the contraction of muscle fibre.
Relaxation of muscle fibres occurs when the nerves stop stimulating. The result in the pumping of Calcium into the sarcoplasmic reticulum which then cause a break in the link that connect actin and myosin. Actin and myosin return to their unbound state leading to the relaxation of the muscle .
Tissues are a group of specialised cells with a common structure, origin and function. For example - epithelial tissue, nervous tissue, muscle tissue.
Plant tissue culture is a practice of propagating plants under sterile conditions, often to produce clones of a plant. Process of tissue culture: A small part of the plant is allowed to grow on a nutrient medium containing all nutrients and hormones necessary for the plant growth
