Properties of important fibres

In this Class 11 Home Science topic from “Fabrics Around Us,” students explore the key properties of important natural and manufactured fibres. They learn how fibre structure affects strength, durability, elasticity, absorbency, lustre, warmth, comfort, and resistance to heat or chemicals. The topic also helps students compare fibres such as cotton, wool, silk, linen, rayon, nylon, and polyester, and apply their properties when choosing fabrics, clothing, and suitable care methods.

01If a person does not quit tobacco but has an otherwise good diet, why is prevention incomplete?

Answer and explanation

Correct answer: D. Because tobacco independently increases the risk of many chronic diseases

A healthy diet cannot cancel the independent harms of tobacco. Smoking and smokeless tobacco expose the body to substances that damage blood vessels, lungs, and other organs and increase the risk of cancers, cardiovascular disease, and respiratory illness. Comprehensive prevention therefore includes tobacco avoidance or cessation, along with healthy eating, activity, screening, and professional support when needed.
