Cleavage is an unique embryological process which transforms the single fertilised egg cell into a sphere of closely aggregated multitude of cells. Immediately after fertilisation the fertilised ovum (egg cell) undergoes a series of cell divisions. These divisions are call..

Basic Proportionality Theorem (B.P.T.) will be more useful in the topic 'SIMILARITY'. Division of a line segment into equal parts. Divide a line segment of length 8.4 cm into 5 equal parts. AB = 8.4 cm 1. Draw AB = 8.4 cm and through A draw another line AX at an acute ..

. From an acellular level of organisation to cellular level and then tissue level, organ level and organ system level of organization can be recognised. In addition, one can recognise the gradual appearance of distinct features such as symmetry, body wall and body cavity. There are further improvem..

Systematic Position - Kingdom : Metazoa Subkingdom: Eumetazoa Division : Bilateria Grade : Eucoelomata Phylum : Arthopoda Class : Insecta Order : Orthoptera Family : Blattidae Genus : Periplaneta Species : america..

Structure of Chromosomes - The most ideal stage to study the structure of chromosomes is the metaphase of mitosis. A metaphase chromosome consist of two identical components called chromatids, which are held together at a specific region called primary constriction. It is usually found in the centr..

Summary - All multicellular animals are now placed in the kingdom of Metazoa. The multicellular animals show a very specific body organisation which ranges from cellular grade to organ system grade. Higher in the hierarchy of animal kingdom, one can recognise appearance of specific features like sy..

>All proteins on partial hydrolysis give peptides of varying molecular masses and on complete hydrolysis yield amino acids. The sequence of amino acids in polypeptide chains present in proteins constitutes its primary structure. The study of shape in which the polypeptide chains exist refers to its..
