harmful bacteria live

These are bacteria which live in a mutually beneficial association with other organisms. Such bacteria derive the essential nutrients from their host organisms and in that process help the host through some of their biological activities. 1. The most familiar example o..

These are bacteria which manufacture organic compounds from inorganic raw materials utilising energy liberated from the oxidation of inorganic substances. Following are the common types of chemo autotrophic bacteria. 1. Nitrifying bacteria which derive energy by oxidi..

Binary Fission - It is the most common mode of asexual reproduction. The cytoplasm and nucleoid of a bacterial cell divide equally into two, following replication of DNA. The cell wall and cytoplasm also split resulting in the formation of two daughter cells. Under favourable conditions, a bacteria..

Metals in the Living System - Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassium. Iron metal is a constituent of haemoglobin in blood which carries oxygen to various parts..

Kingdoms of the Living World..

Summary - In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes..

Antiseptic can be used to kill bacteria or prevent their multiplication. Antiseptics do not harm the living tissues. Therefore, they can be applied on cuts and wounds. Dettol, cetavelon, savlon, acriflavin, gentian-violet, mercuro chrome, boric acid and potassium perm..

It is an antagonistic interspecific interaction in which one species is inhibited while other species is neither benefitted nor harmed. In simple words, in amensalism, one organism does not allow other organism to grow or live near it. It is also called antibiosis and the affect..

Bacteria are omnipresent, occurring in all environments. They occur in water, in air, in soil, and in or on the bodies of living organisms. There are bacteria which occur in hot springs as well as in extreme cold temperatur..

Bacteria may be used as living laboratories for synthesising vitamins, hormones and antibiotics by introducing into them the genes which code for these substances along with the plasmid..
