Introduction - 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 aggregat..

Population and Its Characteristics - Population is the next level in ecological hierarchy the word population has its origin in the Latin word populus meaning 'people'. In ecology, population is defined as the total number of all individuals of a particular species, which breed among them..

Hormones are the chemical messengers of the body. They are defined as organic substances secreted into blood stream to control the metabolic and biological activities. These hormones are involved in transmission of information from one tissue to another and from cell to cell. These substances are p..

Summary - 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, cation..

. Polyploidy may be caused by fertilization of an egg by more than one sperm failure of meiosis during gamete formation. Polyploidy can artificially be introduced by a chemical called colchicine or by crossing diploids with tetraploids. Although triploids exhibit sterility, polyploidy is useful in ..

Golgi complex is represented by several structures like membranes, vesicles and granules. It appears as a central stack of flattened inter communicating sacs called cisternae in a parallel arrangement along with tubules and vesicles. The cisternae are continuously being formed at one end and bud of..

In a Rectangular Cartesian System of coordinates the position of a point in a plane is determined by an ordered pair whose elements give the distances from the intersecting straight lines at right angles to each other. These lines are called the axes. The vertical line is called the Y-axis and th..
