Diffusion and Osmosis

Diffusion and Osmosis are the two activities that preforms the role of transporting materials to or from the cell. Both are the passive transportation, that means such spontaneous process that does not needs any energy. The first one (diffusion) is the movements of molecules from the region of higher concentration ot the lower concentration trough […]


Carbon, oxygen, hydrogen, phosphorus, sulfur and nitrogen are the six elements that are responsible for the occupying 90% of the dry weight of the human body. The other elements that are found in the cells and also play the vital role are Ca, Zn, K, Cl, Mg, Cu, Co, Fe, Se, and Mo. Biological molecules […]


What are Particulates? Particulates, commonly known as Particulate Matter are basically small-sized particles that are present in the air. These particles can be present naturally in air or sometimes these are the result of man-made or anthropogenic activities. The particulates can either exist in the form of small solid particles or liquid droplets. There is […]

Cancer Cells

The uncontrolled division and growth of the abnormal cell in the body differing from the normal cells are the cancer cells. This unrestricted growth of the cells targets the immune system by weakening it, secondly it leads to severe tumors and other fatal impairment. There are numerous types of cancers that can occur inn any […]


What is Leaching? The word ‘leaching’ in reference to the chemical industry corresponds to the removal of chemicals. It is quite a traditional method that involves solid-liquid operation. Traditionally it was regarded as percolation. Leaching is a process where a mixture is diffused or dissolved in liquid in order to separate the solute. More simply, […]

Difference and Similarities Between DNA and RNA

The Central Dogma describes the chronology of the genetic code, from the DNA (Deoxy ribonucleic acid) to the making of RNA (ribonucleic acid) and to protein. There is no short cut of this process, the series of chemical coding and decoding goes in this manner only and if got untracked the consequences can be life […]

Radioactive Waste

What is Radioactive Waste? Radioactive waste, also regarded as nuclear waste is basically such unwanted material or substance that has a high concentration of radionuclides. The nuclear substances over here can occur either naturally or can be the outcome of various man-made activities. The term radionuclide corresponds to the nuclide that has a large amount […]

Herbivores, Carnivores and Omnivores Animals

Our ecosystem consists of varieties of animals. Within their natural communities, the animals even have their particular diet that makes them the participants of the food chain as well. Thus, we can that these living creatures gain their energy directly or from other living things such as plants or animals and hence categorized as the […]

Oxygen Cycle

­­What is Oxygen Cycle? The oxygen cycle tells us about the way the exchange of oxygen takes place in between various environmental segments such as the atmosphere, lithosphere, hydrosphere, and biosphere. Oxygen is a well-known byproduct of the process of photosynthesis. It is one of the elements that exist in ample amounts on the Earth. […]

Klinefelter Syndrome

Klinefelter syndrome is the chromosomal disorder found in males, where the baby boy is born with an extra copy of the X chromosome. It adversely affects the cerebral and physical growth of the males and sometimes it is been diagnosed during adulthood. Klinefelter syndrome severely strike the testicular development significantly and thus the testicles of […]
