1 . Gametes remain pure they either carry dominant or recessive genes Mendel’s principle of segregation is inherent in the results of Mendel earlier described in this section. It is obvious that though in F1 the dominant phenotype appears .....

Here, four hydrogen atom will share each their one electron with carbon to form four covalent bonds. In this way methane molecule is .....

You know that saturated hydrocarbons are the compounds whose all hydrogen atoms and carbon atoms are bonded together with single bonds. For e.g. Ethane. You may also know that when two atoms share their electrons in order to create a .....

Here, we have given  a = 5   and  b = 3 Now  a + b = 5 + 3                                      = .....

The main economic activities of Europe are agriculture, animal husbandry, fisheries, mining, trade and industrial activities. The economic activities of Europe are described in the following ways: .....

The factors favourable for the development of international trade in Europe are stated below: Natural resources: Europe is rich in natural resources. There are thousands of natural resources based industires in Europe. The European Union is .....

The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the .....

Earthquakes can cause huge amounts of death and destruction. For this reason, understanding them is vitally important. Like all major events, seismic or otherwise, they have to start somewhere. The epicenter is the place on the Earth's .....

The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. It is also known as .....

Although 10% of the people are engaged in agriculture, Europe is highly developed. The reasons behind this are as follows: - The variety of climate and physical features have made possible to plant different types of crops in a    .....

Here, we have to find the change in kinetic energy when velocity is tripled. For that, we can find the ratio of obtained value of kinetic energy.  KE  = 1/2mv2 KE'      9/2mv2 or,  KE  =  .....

Let the two number be 6x and 13 x respectively. Here, to find LCM, 1st expression = 6x 2nd expression = 13x Therefore LCM = 13*6x  = 78x. But, given: LCM = 312 or, 78x = 312 Therefore, x = 4. Therefore, the numbers are 24 and 52 .....
