Which of the following is responsible for muscle relaxation?

Biology
1 answer:
Cloud [144]3 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.

Answer:

Because the Arctic glacier is crucial in cooling the land.

Explanation:

The glaciers contained in the Arctic are essential for cooling the earth's climate, which is why Arctic conditions are so important in determining the earth's climate changes.

These glaciers reflect about 80% of the sunlight in the northern hemisphere, and can cool the region's climate. If Arctic glaciers melt, most of the sun's rays will be absorbed by the ocean, increase the temperature and increase the melting of the glaciers.

As a result, the entire ecosystem will be damaged.

<h2>Mitosis Process</h2>

  1. The centrioles absent in the plant.
  2. Animals  cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
  3. The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
  4. <em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
  5. Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each  new nuclei.</em>
