mass selection

Mass Selection - Desirable plants are selected purely based on phenotype and pooled. They are allowed to be grown in mass in next generation. Further selections are made in 3-4 such generations to consolidate desirable characters by ignoring plants ..

The charge to mass ratio is found by measuring the deflection of a ray under the simultaneous influence of electrical and magnetic fields, applied perpendicularly to each other as well as to the direction of the flow of light. This is illustrated in the figure below:..

The organisms show particular patterns of distribution on earth. The distribution of the species give an indication of how the earth was earlier. It is believed that the earth was a single mass called the Pangea. It consisted of two large continental masses called Laurasia and G..

>Mutations: recombinations, genetic drift, natural selection and migration are the main sources of variation. Origin of a new species from the existing one is called as speciation. Speciation can be multiplicative involving splitting of one species into two or more or phyletic involving r..

The submarine is another application of 'Archimedes Principle'. On surface, the submarine floats, with its conning tower and most of the deck, being clear of the water. ..

Solubility of a gas in a liquid increases with the increase in partial pressure of the gas above the solution. Quantitatively, this is governed by Henrys law, which states that at constant temperature. The mass of a gas dissolved in a given volume of the liquid is directly proportional ..

is the mid-point of each interval. Class mark for Class (11 - 15) is . Similarly, class marks for other intervals are 18, 23, 28 When the data is put in a frequency distribution table, the marks obtained by an individual has lost its meaning. Thus some details have been lost. But we have learn..
