Plant Movements - Movement in plants may not be very pronounced, but it is brought about by definite external and internal stimuli. Movement which occur due to external stimuli are known as induced or paratonic movements and the movements which occur due to factors inh..

. This problem of tissue rejection can be overcome by the use of immuno suppressive drugs. 21) When the kidneys are so impaired that they are unable to excrete wastes and regulate pH and electrolyte balance in plasma, Haemodialysis is employed. 22) Advancement in Biomedical engineering has made ..

>The male gamete of one individual fertilizes the female gamete of another individual to produce the zygote. The fertilisation may be external or internal. External fertilisation takes place in animals like the fish and frog where the fertilisation takes place in water, out..

Development is indirect. It involves the occurrence of a larva called tadpole. It is a small, fish-like creature which hatches out from the egg after completing the development. The tadpole swims freely in water feeding on planktonic food. Initially the tadpoles have external gills which ..

To find the co-ordinates of a point C (x, y) which divides the line segment joining the two points A (x 1 ,y 1 ) and B (x 2 ,y 2 ) in the ratio m:n ( internally and externally..

Two identical cells of EMF 1.5 V each joined in parallel provide supply to an external circuit consisting of two resistors of 17 W each joined in parallel. A very high resistance voltmeter reads the terminal voltage of the cell to be 1.4 V. What is the internal resistance..

Prosthesis - Prosthesis is implanting an artificial substitute for a body part either externally or even internally. The branch of surgery dealing with prosthesis is called Prosthetics . Intra ocular lens implanted in the eye following a cataract surgery is a good example. Artif..
