Question

Our hair and nails are composed of……
A) Carbohydrates
B) Proteins
C) Vitamins
D) Fats

Answer 1

Hint: Our body is made up of cells and tissues, this tissue forms different organs which is regulated by different organic matters like vitamins, fats, carbohydrates, and protein. The protein is the organic compounds that are involved in the formation of various body structures.

Complete Answer:
- Keratin is the type of protein that makes up your hair, skin, and nails. Keratin can also be found in your internal organs and glands.
- It is a fibrous protein that makes not just the hair and nails but horns, clews, calluses, hooves, and the outer layer in other animals.
- This protein smooths down the cells of our hairs that overlap to form the strands of the hairs.
- The hair cuticle absorbs the keratin that results in the hair looking shining and full. Some of the foods that help to produce high keratin are; eggs, salmon, onion, sunflower seeds, garlic, etc.
- In nails the keratin is involved in the protection of nails from damage. The nails start growing inside our skin, as the cell grows it pushes the old cell through our skin hence, the part of nails which we can see is the dead cells, so, because of this it does not hurt when we cut our nails.
- The formation of the nails under the skin is maintained by keratin.

Hence, the correct option is (b) Proteins.

Note: Keratin is a protective protein, less prone to scratching or tearing than other types of cells which the body produces.
