Answer:
c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Cardiac muscle is also referred to as myocardium and it's one of the three (3) muscles found only in the heart of vertebrates, the other two (2) being smooth muscle tissue and skeletal muscle tissue.
Cardiac muscle contains bands like skeletal muscle referred to as sarcomeres (contractile units), but its contractions are involuntary like smooth muscle and it's typically being regulated by the sinoatrial node of the heart.
Because identical twins begin as a single fertilized egg that then separates, identical twins share 100 percent of genetic makeup.
<h3>IDENTICAL TWINS:</h3>
Identical twins are a type of twins characterized by their phenotypic similarity. They look so much alike that they are almost morphologically indistinguishable.
Their similarity emanates from their genetic content. Identical twins are formed when two sperms fertilize a single egg, which then splits into two.
Since identical twins begin as a single fertilized egg that then separates, this means that they share 100% of their genetic makeup.
