Which of the following is responsible for muscle relaxation?

Biology
1 answer:
Cloud [144]4 years ago
5 0

Answer:

Option-C

Explanation:

The process of muscle contraction and relaxation is very complex and involves the electrical signals, calcium ions, ATP, proteins- actin, myosin, troponin, tropomyosin, and many others.

The process of muscle contraction begins when the neural signals lead to the release of the sarcoplasmic calcium ions and then calcium binds to troponin and allows the binding of the tropomyosin and formation of cross-bridge.

The muscle relaxes when the signals from the brain stop the release of the calcium ions from the sarcoplasmic reticulum and the released ions are pumped back in the reticulum.

Thus, Option-C is the correct answer.

When gas molecules begin to clump together in molecular cloud they increase the
Schach [20]

At the center of the cloud, more weight of the gas molecules are present.

The mass or weight at the center of the cloud increases when the gas molecules group together in a molecular cloud because more gas molecules are present at the center which combines with each other leads to heavier weight of gas molecules. The combination of gas molecules make the center of the molecular cloud denser as compared to other parts of the cloud so we can conclude that increase in mass occur at the center of the cloud.

viruses and other things don't pass this check and things like white blood cella come shut it down.

that's why doctors poison the area they find the cancer. to send white blood cells there to shut the area down not passing the check.
