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 ..

The maximum number of individuals of a population, which can be provided with necessary resources for healthy living, is called carrying capacity of the habitat. Size of a population increases till it reaches the carrying capacity of the habitat. When the resources become short of requirement, the..

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..

The functional group is an atom, or a group of atoms which can replace one or more hydrogen/s in a hydrocarbon. This group when present in organic compounds defines the characteristic physical and chemical properties of that particular family of organic compounds. Thus a functional group is the si..
