Answer 2

Striated or striped muscle fibers show light and dark bands.

• Striated muscles are made with elongated muscle fibers those are generally called it as Cardiac muscles.

• Myofibrils contain proteins called actin and myosin. These two proteins represent the light and dark bands.

• The light band contains actin protein this is called an isotropic band or I -band.

• The dark band contains myosin that is called A-band or Anisotropic band.

• Stripped muscles or striated muscles continuously changing the bands of actin and myosin.

• That's why we can see light and dark bands in Striated muscles.
