Answer: A
Explanation: The answer is A.
- The presence of calcium in the sarcoplasm is directly responsible for exposing the binding sites on actin.
- Rigor mortis occurs after death because detachment of crossbridges does not occur due to the lack of ATP
<h3>What is Sarcoplasm?</h3>
This is defined as the the cytoplasm of striated muscle cells in living organisms .When calcium is present, the binding sites on actin are exposed.
Rigor mortis occurs after death and involves stiffening of the muscle tissue because detachment of cross bridges does not occur due to the lack of ATP.

True, major events like a super volcano's or asteroid strikes can send tons of ash dust and debris into the stratosphere and cause global cooling. <span />
The three situations in which ionic reactions go to completion is formation of a gas, a precipitate and a slightly ionized product.
<h3>What are ionic reactions?</h3>
It indicates the flow of electrons and, therefore, the bonds broken and formed in the course of the reaction. It is theoretical, it can be corroborated by experiments, but sometimes there is no consensus on the mechanism by which a certain reaction occurs.
Chemical reactions are the result of the transformation that occurs in substances, where atoms rearrange themselves, modifying their initial state. Thus, chemical compounds undergo changes generating new molecules. In turn, the atoms of the elements remain unchanged.
