The advantages associate with digital communication systems include (i) A common format for encoding different kinds of message signals (e.g., speech signal, video signal, computer data, etc.) for the purpose of transmission. (ii) An improved security of message. (iii) Increased immunity..

The offsprings are genetically identical and therefore advantageous traits can be preserved. Only one parent is required which eliminates the need for special mechanisms such as pollination, etc. It is faster. For example, bacteria can multiply every 20 minutes. This helps the org..

an indefinite number of plants can be raised from a small mass of parental tissue. It is useful for obtaining virus free healthy plants. An unlimited number of plants are produced within a relatively short time..

1) More efficient than conventional cells because the energy of the fuel is converted directly into electric energy. Efficiency = 60-70%. 2) They are free from polluti..

Friction aids walking. Our feet pushes the floor back and the floor pushes our feet forward, by using friction to do so (every action has equal and opposite reaction). Friction between tyres of vehicles and the road make controlled motion possible. Many machine parts stay in place and are a..

Gear systems are very efficient at transferring energy. Some gear boxes are 95% efficient i.e., they only waste 5% of the energy they transfe..

1) Provides imaging of disease tissue with superior resolution power and best pictorial form. 2) Gives information about chemistry, metabolic and bio-chemical data. 3) Non-invasive. 4) Not utilising radiations and so with no side effects. 5) Can study, mostly all body parts as water is present in ..

a) It prevents the back suction of water into the apparatus. b) It provides a larger surface area for dissolution of hydrogen chloride g..

Advantages of Asexual Reproduction - There is no need for sexual partners. It is a very rapid proces..

One advantage of wind energy is that it is available everywhere and in plenty. We will never run out of wind power. It does not create any kind of pollution; like smoke and harmful gases or harmful radiatio..
