Larynx is a part of the throat. It is responsible for production of sound.
Larynx moves when we swallow something. Inside the larynx, there are two vocal cords. There is a small gap between them. This small gap allows air to pass through. When we speak, air is forced into this small gap by the lungs. This prompts vocal cords to vibrate. Since vibrating objects produce sound, sound is produced due to the vibration of vocal cords.

Pasteurisation is one type of food preservation method. Pasteurisation is the process developed by Louis Pasteur, especially to store milk. In pasteurisation, milk is first heated to about 70 degrees Celsius for 15 to 30 seconds. Then it is suddenly chilled and stored. This prevents the growth of microbes. Pasteurisation deactivates the microbes and reduces the enzyme activity by reduction of temperature.

Those organisms which are too small to be seen without a microscope are called microorganisms. Microorganisms are present in soil, water and air around us. They are classified into four major groups – bacteria, fungi, algae and protozoa. Viruses are also microorganisms but they need a specific host for their reproduction. Some of the microorganisms are harmful to us as they cause diseases in human, plants and animals. Diseases like polio and chicken pox are caused by viruses. Diseases like dysentery and malaria are caused by protozoa (protozoans) whereas typhoid and tuberculosis (TB) are caused by bacteria.

Friction: When one surface is moving over another surface, a force comes into play and opposes their relative motion. This force is called friction or force of friction. Friction always opposes motion because it acts in opposite direction to motion. Force of friction arises due to contact between two surfaces. If there is no contact between two surfaces there would be no friction.
