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 gro..

The heart is regulated to a large extent through the central nervous system. The heart nerve branches from the vagus nerve from the medulla oblongata and the sympathetic nerve fibres from the spinal cord. The vagus nerves are cardiac inhibitory nerves. When the vagus nerve is stimulated, ..

In eukaryotes, the genes that code for the enzymes needed to catalyse the various steps of a particular metabolic pathway may not be adjacent or even be in different chromosomes. However, these genes are regulated by operon model as in bacteria. Both the inducible and the repressible syst..

Find the location of the vertex D, if ABCD forms a square. => (6, 6) or (6, 3) or (3, 3) or (3, 6)..

This is also a fat soluble vitamin. Ergo calciferol and cholecalciferol are the provitamins of vitamin D. Ergocalciferol is vitamin D 2 formed from ergosterol. Cholecalciferol is vitamin D 3 found in animals. Vitamin D is stored in liver and othe..

Take very thin iron wire or iron wool and coil it around a matchstick. Light the matchstick and introduce it into a jar of oxygen. The iron will start burning with or without flame, but with a crackling sound, to form tri-iron tetroxide or magnetic oxide of iron. It is advisable to place..

This Hybridization involves the mixing of one s, three p and one d-orbital. These five orbitals hybridize to form five sp 3 d-hybrid orbitals. The mixing of five orbitals is shown in figure 1.23. These hybrid orbitals point towards the corners of a trigonal bipyr..

Aldehydes react with alcohols in the presence of dry HCl gas to form acetals a gem-dialkoxy compound. In this reaction, the addition of one molecule of alcohol to one molecule of aldehyde results in the formation of an alkoxy alcohol intermediate known as a hemiacetal. A hemiacetal conta..

Such salts are formed by the intimate association of two simple salts, when crystallized from a solution of a mixture of the two. Some Common Double Slats Potassium alum K 2 SO 4 Al 2 (SO 4 ) 3 .24H 2 O Ammonium alum (NH 4 ) 2 SO 4 . Al 2 (SO 4 ) 3 24H 2 O ..
