Which process must occur for a muscle to be able to relax?

Biology
1 answer:
LuckyWell [14K]3 years ago
8 0

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 .

<h2>Cell Cycle </h2>

Explanation:

Eukaryotes grow and divide by cell cycle.

The main parts of a cell cycle are an ordered series of events – Gap 1 or G1 phase, Synthesis or S phase, Gap 2 or G2 phase, and the mitosis or M phases.  

Interphase period (G1, S, G2 phases) - cell grows by size, duplicates its content, replicates its DNA, and finally prepares for mitotic cell division .

Mitosis and cytokinesis - formation of two identical daughter cells

Cell cycle is regulated by regulatory or restrictive checkpoints in the cell cycle which are activated with detection of a defective DNA.

Proliferation of undesired or cells with defective DNA like in case of tumor cells is controlled by the action of suppressing agents like p53 and cyclins.

The tumor suppressor gene protein p53 prohibits division of tumor cells. Cyclins regulate cell cycle by activation of the enzyme cyclin-dependent kinase.

Explain how the data supports your hypothesis.
Viktor [21]

Answer: It is verified by testing it. If the data supports the hypothesis, then we consider the hypothesis to be verified and true. If however, the data does not support the hypothesis or refutes it, then the hypothesis is in trouble, and we have to come up with a different hypothesis to explain the observations.
