How tall is Shaquille O'Neal. American basketball player. He has stated 7ft 1 as his height. He was measured just under the mark, although DraftExpress noted that he was supposed to have been measured 7ft without shoes in 1992 and it is possible he was near 7ft 1 in shoes..
With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body.Carbon dioxide passes from the blood through the thin gill tissue into the water.Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians.n the larval dragon fly, the wall of the caudal end of the alimentary tract (rectum) is richly supplied with tracheae as a rectal gill, and water pumped into and out of the rectum provides oxygen to the closed tracheae.
Myofibrils are constructed and lined up in a chain-like formation to create what are called sarcomeres. Sarcomeres contain several regions. One region is called the A-bands and only consist of myosin filaments. The counterpart of A-bands is the I-bands that only contain actin filaments.The ends of each sarcomere are called Z discs.A middle region of each sarcomere called the H-zone only contains myosin. According to the sliding filament theory by Andrew Huxley and Ralph Niedergerke, muscles contract when Z-discs come closer together thus shortening the sarcomeres.s this overlap occurs, myosin filaments are binding to the actin filaments, allowing myosin to function as the driving motor of filament sliding. This relative movement between myosin and actin is what results in muscle contraction.
