Immunity is defined as the ability to eliminate complexes of protein molecules differing in structure from those present in the healthy animals. There are two kinds of defence mechanism against microbes a) nonspecific defence mechanism b) specific defence mechani..

Thus, Respiration can be broadly defined as "the breakdown of organic compounds into simpler compounds accompanied by the release of energy in the form of ATP" Since most often the substrate is glucose, the general equation for respiration can be written as follo..

Let R i denotes the i t h row of the matrix A = [a i j ] then the elementary row operations on the matrix A are defined as: 3. R i g R i + kR j means multiply each element of j t h row by k and add it to the corresponding elements of i t h row. The corresponding column tra..

Let (B, +, ., ', 0, 1) be a Boolean algebra where B is a non-empty set, '+' and '.' are binary operations, ' is a unary operation with two special elements 0 (Zero element) and 1 (unit element). Let x 1 , x 2 , x 3 .x n are in B. Then Boolean expression in x 1 , x 2 , x 3 . x n are definedh..

The figure is a unit circle, with origin O as centre cuts the x-axis at A (1,0) and let a variable point moving on the circumference move through an arc length q . i.e., AP = p( q ). The coordinates at the position of p( q ) are p(x,y) = (cos q , sin q ). Then the tangent function is def..

Magnetic flux can be defined as the number of lines of force passing through a surface normally. Considering the surface ' D s' in a magnetic field 'B..

A chromosome map is a graphic representation of a linkage group in the form of a line which shows by points the sequence of the genes and the relative distance between the genes it contains. A chromosomes map is also called a linkage map or genetic map. Since the frequency of crossing over is used ..

Presence of dangerous unnatural ingredients causing imbalance in the ecosystem and health hazards to human beings and animals can be called as pollution. That is, pollution is a phenomena where natural ingredients are replaced or damaged by presence of dangerous unnatural ingredients - which have p..

Production of offsprings by a single parent without the formation of gametes is called asexual reproduction. It is also called as somatogenic reproducti..

Two or more substances having the same molecular formula but different structural or spatial arrangement are called isomers. These are of two types: a) Structural isomerism b) Stereo isomeri..
