Answer:
The correct order is: 6) Sarcoplasmic reticulum releases calcium ions, 2) Calcium ions bind to troponin, 5) Tropomyosin moves to expose active sites of actin, 4) ATP is split into ADP and P, 1) Myosin head binds to actin, 7) ADP and P released from myosin, 3) Myosin cross-bridges bend, pulling actin toward center of sarcomere.
Explanation:
The ability to contract is an important property of the muscle cells and is fundamental to animals because muscles not only make locomotion possible but are also responsible for the correct functioning of organs (including the heart).
The mechanism behind muscle contraction is the sliding of filaments in a structure called sarcomere, which mostly involves the presence of actin and myosin filaments.
For muscle contraction to happen, there needs to be a <u>stimulus coming from the nerve that innervates said muscle</u>. This stimulus generates the release of <u>calcium ions</u> that will bind to a protein called troponin and will lead to the exposure of the active site of actin so it can bind to the myosin head. <u>This process requires ATP</u>.
The sun like all stars is constantly using up its (Fuel)
so eventually like all other stars it will create a supernova and we would all die
thankfully that won't happen for another 5 million years
Answer: The answer is BOUNDARY
Explanation:
The appropriate response is aponeurorrhaphy. Aponeurorrhaphy alludes to the stutured of an aponeurosis, which is the more profound and thicker band of stringy connective tissue appending muscles to bones. It is a strategy in which the solid sheet of tissue that fortified the patient's muscle to close-by bone.
The correct answer is: post-industrial community (society).
Post-industrial community is the society in which service sector brings more wealth than the manufacturing sector of the economy. In this kind of society, knowledge is valuated and producing ideas is the main way to grow the economy of that society.
