>Simplified Diagram of the Heart Therefore, the right side of the heart is concerned with the deoxygenated blood and the left side of the heart is concerned with the oxygenated blood. Further, the auricles are the receiving chambers and the ventricles are the pumping chambers. When the ventricles p..

Respiratory System in Human Beings The respiratory system starts with the nose that encloses the nasal cavity. The nasal cavity opens to the outside through the openings called the nostrils. The nasal cavity is divided into two portions by a cartilagenous septum and is lined by fine hairs that..

The most ideal stage to study the structure of chromosomes is the metaphase of mitosis. A metaphase chromosome consist of two identical components called chromatids, which are held together at a specific region called primary constriction. It is usually found in the centre and hence it is..

Ecosystem - Structure and Function - The characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. The two main structural features of any ecosystem are its ..

> hybrid carbon of an aromatic ring. The bond angle This is due to partial double bond character on account of the conjugation of unshared electron pair of oxygen with the aromatic ri..

Biogeography reveals that living organisms (plants and animals) are found practically everywhere on this earth. The living components interact among themselves as well as with their physical environment like soil, air and wate..

Introduction - Biogeography reveals that living organisms (plants and animals) are found practically everywhere on this earth. The living components interact among themselves as well as with their physical environment like soil, air and water. The branch of biology, which deals with the relationshi..

. They show a (9+o) arrangement of microtubules. They are involved in the formation of spindle fibres during cell division and the basal bodies of cilia and flagella. Cilia and flagella are found in the surface of motile cells. They show a (9+2) arrangement of microtubules. These str..

Man has a pair of ears that function as the organs of hearing and the organs for equilibrium. It has two different structures for each of these functions. Both these structures have receptors that convert the vibrations into nervous impulses that are transmit..
