Excretory System Of Cockroach - The excretory organ of cockroach is the malpighian tubules. It is found at the junction of the midgut and hind gut and are about 150 in number. They are fine, yellow coloured and branched threads present in bundles. They lie freely in the haemolymph. The di..

(a) The student has a relatively large rotational inertia about the rotation axis and a relatively small angular speed. (b) By decreasing his rotational inertia, the student automatically increases his angular speed. The angular momentum of the rotating system remains unchanged. So, if th..

It is the movement of water between aquatic systems, air and land water vapour condenses to form clouds, and eventually rainfall. Plants play an important role in this cycle by the process of transpiration. The upper limit (maximum) of water availability of a soil is called field capac..

The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics). The first law of thermodynamics is the law of conservation of energy, which says that 'energy can neither be created nor destroyed but can be transformed from one..

The PS-II reaction centre (P 6 8 0 ) by transferring electron to primary acceptor becomes oxidise..

">The phenomenon by which, a ray of light splits into its constituent colours, when passed through a transparent medium, is known as dispersion. The band of colours obtained due to the dispersion of light is called the spectrum. Atmospheric Refraction Atmospheric refraction is the shift in apparent..

The state of equilibrium is a state in which the measurable properties of the system do not undergo any noticeable change under a particular set of conditions. We have seen that all observable properties of a system become constant at equilibrium. It may lead us to think that ..

to [A] o . The rate constant k of the reaction is given by, The time taken for the initial concentration to reduce by half is given by, From the t 1 / 2 relation, the rate constant k can be calculated. Reactions in heterogenous system usually follow zero order kinetics. In such a sys..

>Space-based remote sensing is a new technology. It has high potential for applications in nearly all aspects of resource management. India recognized the potential of this technology quite early. India conducted several remote sensing experiments in the late '60s and '70s using airborne sensors an..
