Which of the following is true for the labelled parts in the figure below?
1 A - Z-line- located at centre of I-band
2 B- Thin filament -occurs in A-band only
3 C- Thick filament- confined to I-band
4 D- H-zone-located at centre of M-line
Explanation:
Exp. A In the center of each ' \(I\) ' band is an elastic fibre called ' \(Z\) ' line which bisects it. The thin filament are firmly attach to ' \(Z\) ' line. The portion of the myofibril between two successive ' \(Z\) ' line. It is a functional unit of contraction and is called a sarcomere.

Sarcomere is the functional unit of contraction in a muscle fibre. Identify the portion of myofibril that constitute a sarcomere.
1 The portion of myofibril between two successive 'Z' line.
2 The portion of myofibril between two successive 'I' band.
3 The portion of myofibril between two successive 'A' band.
4 The portion of myofibril between two successive 'M' line.
Explanation:
Exp. A A Sarcomere is the functional unit of construction in a muscle fiber. It is the repeating unit of the myofibril which is the contractile element of a muscle fiber. A portion of myofibril between two successive "Z" line constitute a Sarcomere. Sarcomere consist of two types of band i.e. 'I' band which is known as 'light band are thin filament and called 'Actin' while 'A' band which is known as 'dark band' are thick filament called myosin.

Colour blindness is due to defect in
1 cones
2 rods
3 rods and cones
4 rhodopsin
Explanation:
Exp. A Colour blindness is due to defect in cone cell. They are found in the light sensitive layer of tissue at the back of eye, called retina. Colour blindness occurs when tissue is problem with the pigment in certain nerve cells of the eye that sense colour. Rod cell are the other type of photoreceptor present in the retina. They are responsible for vision in low light conditions.
