what causes cell specialization

Causes of Cancer - A chemical or other environmental agent that produces cancer is called a carcinogen. The world Health organisation estimates that carcinogens may be associated with 60 - 90% of all human cancer. Depending upon their mode of action carcinogens are of 3 types. (1) Carcino..

Kidney failure is caused due to many reasons: (a) Tubular injury (b) Infection (c) Bacterial toxins (d) Inflammation of glomeruli (e) Arterial or venous obstruction (f) Fluid and electrolyte depletion (g) Intrarenal precipitation of calcium and urates. (h) Drug reaction (i) Haemorrh..

1. The parents of these students do not place much importance on education. At the least provocation, they take the children out of school. Girl students are especially vulnerable. For them the household chores - carrying water, looking after siblings and marriage are considered more important. 2...

.8 - Cell Structure of Cyanobacteria The planktonic forms contain gas vacuoles in their cells to help in floating. Some cyanophycean members possess special types of cells called heterocysts, as in Anabena and Nostoc. They are large, thick walled, round ..

Properties of Cancer Cells - 1) Cancer cells show uncontrolled mitotic divisions causing unorganised growth 2) Due to uncontrolled growth and division of cells, a tumour (also called Neoplasm is generally formed) 3) Cancer cells are far less adhesiv..

The Concept of Half-cell - A galvanic cell consists of two electrodes dipping into the same or two different electrolytes. No reaction takes place until a conducting wire joins the two electrodes. Once, a chemical reaction takes place at each electrode, electron transfer takes p..

Advantages of Using Solar Cells - It is present in abundance They have no moving parts and hence require little maintenance and work quite satisfactorily without any focusing device It does not cause any environmental pollution like the fossil fuels and nuclear power Solar ..

Calculation of Cell Potential - In an electrochemical cell, electrons flow from negative electrode to the positive electrode. This shows that there is a potential difference between the two electrodes. The minimum potential which causes the flow of the electrons from t..

In some plants, the roots undergo modification to perform special functions, such as storage and respiratio..
