Organisms look similar because their body designs are similar. If body designs are to be similar, the blue prints for these designs should be similar. Thus, reproduction involves making copies of the blueprints of body design. The chromosomes in the nucleus ..

Indigenous dairy breeds produce 6-8 litres of milk a day where as foreign exotic breeds produce 60 litres of milk a day. Even the lactation period (period when milk is produced) is longer. To improve the production of milk of our Indian cows, crossbreeding programmes are conducted at various dairy ..

Research organizations have developed improved storage structures which have proved comparatively safe for the storage of grains. In these structures, temperature, moisture, oxygen and carbon dioxide can be adjusted to protect the grains. The structures are airtight, moisture impervious,..

The bacterium that causes this disease is Mycobacterium tuberculosis which is a rod shaped bacteria spread by air, dust, sputum of infected person or even from animals.

A Search for the Particles of Atom of Electrons - Although Dalton's theory of the existence of atoms was published in 1808, there was no clear idea of what an atom might look like until the early part of the twentieth century. With the advent of electricity and phenomenon of spectrum, experiment..

A solar heating device is one which allows collection of a large amount of heat from the sunlight in a given region and restricts the loss of heat to the surrounding in the form of radiation. The following facts help us to design an efficient solar cooker: A black body absorbs maxi..

The following are some improved breeds of dairy cows that have been developed in our country at the National Dairy Research Institute (NDRI), Karnal, Haryana. Karan Swiss : This is a crossbreed between Brown Swiss and Sahiwal Karan Fries: This is a cross breed between Holstein-Fries..

Environmental Consequences - The energy source that we actually choose depends on various factors like the cost, the ease with which it is available, the efficiency of the technology available and the environmental damage that will be caused by using that source. It is thus debatable as to whether ..

All round us we see different organisms from the lowest forms to the highest. Species differ from each other. However, the variation we focus relates to the differences among individuals of a species. No two individuals are identical to each other. While we acquire a common body design, ..
