Yogita Ingle 7 years, 4 months ago

Take a beaker and half fill it with water. Drop some crystals of potassium permanganate in it. Now, heat the beaker and watch the movement of the coloured solution. In this activity, the liquid at the bottom of the flask gets heated first. This warm liquid, being warmer than the surrounding cool liquid, rises up. The colder liquid moves down, gets heated and in turn rises up again. The heat is transferred from the hot water at the bottom of the beaker to the cooler water at the top by the actual movement of the water itself.

Yogita Ingle 7 years, 4 months ago

Bacteria are known for their simple body design. They are single-celled microorganisms with the absence of the nucleus and other cell organelles. They are prokaryotic organisms which are present almost everywhere around us from soil to human guts.
Bacteria are grouped into five based on their shapes such as rod-shaped bacilli, spherical, cocci, spiral-shaped spirilla, and corkscrew spirochaetes. They may either be in clusters or chains or pairs or single. Another criterion for classification of bacteria is by using of staining techniques. For e.g. Gram-positive and Gram-negative bacteria.
