The sarcomere is the basic contratile unit of muscle i.e the unit responsible for contraction in the muscle and it consist of two main protein actin; which forms filaments involved in contraction and myosin; a motor protein responsible for contraction. Calcium interacts with these protein and in the absence of Ca, contraction is inhibited (sacromere with not be able to undergo contraction)
Answer:
It would definitely be A

<span>The most dominant chemolithotrophs in pelagic waters are ammonia-oxidizing archaea. The first step in nitrification is performed by ammonia oxidising microorganisms that convert ammonia into nitrite ions. Science has known about nitrifying bacteria for over a hundred years now thanks to the discovery of S. Winogradsky.</span>
