1. What is a balanced diet? What should it contain?

Ans. A balanced diet is one that contains all the necessary nutrients in the right proportions. It should include adequate amounts of fats, carbohydrates, proteins, vitamins, and minerals.

2. Why is it important to include roughage in our diet?

Ans. Roughage or fiber absorbs water and swells up in the intestine. This adds bulk to the feces, keeping it soft and facilitating smooth movement through the rectum. Roughage is important for preventing constipation and is an essential part of our diet.

Class 6 Basic Science Chapter 2 – Part C

1. Describe how you would find out whether protein is present in a particular food.

Ans. To determine the presence of protein in a specific food, we can perform a protein test. First, add a few drops of concentrated nitric acid to egg white or a paste of soya bean flour in a test tube. Heat the test tube until its contents turn yellow. Transfer the acid to a beaker and add a few drops of ammonium hydroxide into the test tube. Shake the test tube. If the contents turn violet, it indicates the presence of protein in the sample.

2. Why is it necessary to drink about 1.5 litres of water every day? How would you show that vegetables contain water?

Ans. Water is essential for many vital functions in our bodies.

(a) Chemical reactions, like digestion, occur in a dissolved state in water.

(b) Digested food is transported throughout the body by water.

(c) Waste is eliminated from the body in the form of sweat and urine.

(d) Chemicals and gases are carried in the bloodstream by water.

(e) Sweating helps regulate body temperature.

We lose 2-3 liters of water daily through excretion, sweating, and breathing. We replenish around 1.5 liters by drinking water and other liquids, while the rest comes from food.

To measure the loss of water from a vegetable, such as a potato, slice it into thin wafers. Weigh the slices and let them dry in the sun until they become brittle. Weigh them again and note the difference in weight. The weight loss indicates the water loss from the potato due to drying in the sun.
