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:
Both of these daughter cells will then go on to divide once more in meiosis II, producing 4 daughter cells, 2 with n+1 and 2 with n-1. Nondisjunction in meiosis II results from the failure of the sister chromatids to separate during anaphase II.
Carbon dioxide controls the amount of water vapor in the atmosphere and thus the size of the greenhouse effect. ... This means that Earth's temperature will increase at least another 0.6 degrees Celsius (1 degree Fahrenheit) because of carbon dioxide already in the atmosphere
