all organisms capable of fixing nitrogen belong to the group

Nitrogen Cycle - Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assim..

>When nitrogen is heated with calcium carbide at 800 o C to 1000 o C, nitrolim an important fertilizer is formed. Nitrogen is used in high temperature thermometers, as a refrigerant and in electric bulbs. Nitrogen cycle charts the circulation of nitrogen comp..

Summary - Chlorine belongs to group VII A. Members of this group are called halogens which means 'salt producers'. Chlorine is a greenish yellow gas. Chlorine has seven electrons in its outer most shell and so has a valency of 1. Like other halogens chlorine is a stron..

The nitro group is an ambident group and is capable of getting attached to carbon chain through nitrogen..

Two carbon atoms joined by a single bond are capable of free rotation about themselves. When two carbon atoms are joined by a double bond, they cannot rotate freely and the relative positions of the various groups attached to these carbon atoms get fixed. This gives r..

A homologous series is a family of organic compounds containing a particular characteristic group and exhibiting similar properties. For example, the compounds given below belong to the alcohol family. CH 3 OH methyl alcohol (methanol) CH 3 CH 2 CH 2..

The growth of plants is regulated by certain chemical substances, which are synthesized by the plant in very small quantities. These substances are formed in one tissue or organ of the plant and are then transported to other sites where they produce specific effects on growth and developm..

>The genetic material is made up of chromatin or the chromosomes that consists of two strands called the chromatids held together by the centromere (decides the shape of the chromosome) Chromosomes contain the genes that are arranged in a linear fashion. Each gene is a short chain of nucleotides ar..

A tissue is a group of cells having a common origin, similar structure and performing a common function. Tissues are characteristic of advanced multicellular animals, commonly called as eumetazoans. They are true multicellular animals where the body cells aggregate to form tissues, o..
