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.

Augustus "Smiling Gus" Winkler was a big-time gangster who had his fingerprints surgically altered so as not to be identifiable through fingerprint technology. He was part of Eagan's Rats gang and would participate in some of the most notorious crimes such as the St. Valentines Massacre in 1929.
When he moved up north, he met up with some of the world's famous gangsters like Al Capone, Roger Touhy, Fred Burke, and Bugsy Moran.
