advantages

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 organis..

1) Safer than radiography as there is no exposure to radiation. 2) Non-invasive and painless. 3) Comfortable and inexpensiv..

They give better thrust than solid propellants By propellant flow regulation, thrust can be controlled A mixture of liquid oxygen and liquid hydrogen is one of the most important liquid propellants. Oxygen burns liquid hydrogen to produce heat energy. Liquid propellant examples are alcohols,..

The demand for electricity varies at different times of a year. One big disadvantage is that the wind, waves and tides do not occur at all time and hence cannot guarantee steady production of electricity. Hydroelectric power stations can solve this problem. When the demand is low, excess power gene..

It can be used to measure temperature accurately because of its electrical nature and a wide range of temperature difference(0.001K - 2000K) It absorbs a very small amount of heat from the object and therefore does not change the temperature to be measured. As the thermal capacity is low, i..

fig. 12.3 - Relation of Surface area to Volume Multicellularity provides division of labour through specialisation. It provides specific advantages, such as It avoids duplication of work. It ensures simultaneous and uninterrupted performance of the life activities. It increases the chance..

High calorific value Complete combustion: No residue No smoke No pollutants Burns readily, preheating not required. This is because it has a low ignition temperature..

Due to friction we are able to walk on the surface of the Earth The brakes applied in automobiles work only due to friction Nails, screws and the wooden boards are held together due to force of friction The fibres of thread are held together due to force of frictio..

There is no need for sexual partners. No chance for combinations, so no variation in the populatio..
