Is Heart made up of striated or non striated muscles?
Heart muscle is striated but not in the same way that skeletal muscle is. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.Cardiac and skeletal muscle are similar in that both appear to be striated in that they contain sarcomeres. In striated muscle, such as skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length on the order of a few micrometers, far less than the length of the elongated muscle cell (a few millimeters in the case of human skeletal muscle cells).The filaments are organized into repeated subunits along the length. These subunits are called sarcomeres. The sarcomeres are what give skeletal and cardiac muscles their striated appearance of narrow dark and light bands, because of the parallel arrangement of the actin and myosin filaments.However, cardiac muscle has unique features relative to skeletal muscle. For one, the myocytes are much shorter and are narrower than the skeletal muscle cells, being about 0.1 millimeters long and 0.02 millimeters wide .Furthermore, while skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles.Anatomically, the muscle fibers are typically branched like a tree branch. In addition, cardiac muscle fibers connect to other cardiac muscle fibers through intercalcated discs and form the appearance of a syncytium (continuous cellular material).These intercalcated discs, which appear as irregularly-spaced dark bands between myocytes, are a unique and prominent feature of cardiac muscle .
Suppose you had 500 pieces of each of the four fragments how would the gel appear?
It depends on the length of your four fragments. If the 4 fragments are same in length, you can not distinguis the band on the gel as all the (4x500) molecules run at the same length. If they are different in size let say 100,200,300,400 you can see four distinct bands. The intensity of the bands may be stronger at 400 and drops down to the lower fragments because of the higher molecular mass.
What does a Jewfish look like?
An adult jewfish has dull olive brown color with faint spots and bands. They can grow to a length of 8 feet and weigh 700 pounds.
What is outer feeder bands?
Normally there are outer bands and feeder bands. I'm not sure what outer feeder bands are. Maybe they are just feeder bands Bands refer to a continuous line or circle of showers and thunderstorms. Outer bands are the showers and thunderstorms on the outside edge or perimeter of a hurricane (typhoon). . Feeder bands are the showers and thunderstorms between the outer band and the eye-wall of a hurricane (typhoon).
Do igneous have bands of crystals?
No, they do not have bands of crystals but they are all crystalline.
What length decreases when sarcomere shortens?
I-bands
Which region of a sarcomere shortens during contraction?
During a contraction, the I bands and H zone of a sarcomere contract. The A bands remain unchanged.
In skeletal muscle where is the z-line?
Actin molecules are bound to the Z line, which forms the borders of the sarcomere. Other bands appear when the sarcomere is relaxed. The Z line is found between two sarcomeres.
How many Bands is Christopher Drew in?

What band does not change its length during shortening of the sarcomere?
the A-bandsthe A-bands
What is the length of royal mail rubber bands?
If you cut on so that it forms a single length its length is 15.5 cm (I've just done it to find out).
Do the you band and H zones become narrower during contraction?
Yes the H band shortens. During contraction the length of the sarcomere or from z line to z line must decrease in length. Thus the I band which is bisected by the z line must shorten as well as the H band, even though the H band is bisected by the A band it must shorten to allow fior this decrease in length. The A band does not shorten because it is composed of the entire length of myosin whose length never decreases during contraction.
How much rubber bands does it take to do a raindrop loom bracelete?
The Raindrops Bracelet requires 52 rubber bands when made on a single length of the Rainbow Loom, not including any bands used for an extension: 28 A color bands, and 12 EACH of B and C color bands.
When a muscle fiber contracts the you bands diminish in size the h zones disappear and the a bands move closer together but do not diminish in length true or false?
True
