The positively charged particles were discovered by E.Goldstien. He modified the discharge tube experiments by using a perforated cathode and after evacuating the tube he applied high voltage across the electrodes. Apart from the usual cathode rays emerging from the perforations, he foun..

Goldstein experimentally proved the existence of positive charge in matter. In his experiments, a perforated cathode was used in a discharge tube along with air at very low pressure of about 0.001 mm of mercury. When a high voltage of about 10,000 volts was applied to this cath..

The word 'ultimate' has many connotations. Here, it means the most terrifying and exciting experience the unpleasant experience of suffering. The word safari means journey through an animal park..

Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Thomson led to t..

Structure of the Atom - Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Tho..

Totipotency is the capacity of a living cell to differentiate into any type of cell forming a new organism or regenerating a lost part of the body. A cell exhibits totipotency because it contains the entire genetic information in its nucleus. This information is expressed when it becomes necessary...

Reasons for Mendel's Success - Many scientists earlier to the period of Mendel had attempted breeding experiments in both plants and animals. However, most of them failed to arrive at any specific conclusions or principles to explain the pattern of inheritance. In fact, many of ..

New species can be created by domesticated animal husbandry for better and yield. For example, a new species of domestic sheep were created by hybridisation that no longer produced viable offspring with the parent species. Domestic cattle on the other hand, with several varieties such as..
