cross multiplication

Polymers - high molecular mass macro-sized molecules consisting of repeating units of monomers - may be synthetic or natural in origin. Addition polymerization are usually performed on alkenes and their derivatives and proceed through chain growth mechanism involving radicals, cations and anio..

>The arrangement of sepals and petals in the bud condition, is known as aestivation. It is of 4 different types such as valvate, contorted(twisted), imbricate and quincuncial. The essential whorls of a flower are represented by androecium and gynoecium. Androecium is the male whorl of the flower. I..

All of the changes, diversifications, and extinctions that happened over the course of life's history are the patterns of overall evolution.

>Full names of the units do not begin with capital letter E.g., newton and not Newton. The symbols of units, named after a scientists, have initial capital letter. E.g., J for joule, K for Kelvin. Symbols do not have plural form. E.g., 5 kg (not 5 kgs), 25 m (not 25 metres). A unit symbol is repres..

. Each carpel bears many ovules each of which contain one egg, the female gamete. Each ovule bears the embryo sac that contains the egg and the polar nuclei in addition to other structures. Transfer of pollen grains to the stigma is called pollination. Pollination may be self-pollination or cr..
