Introduction Cell division is the process of multiplication of the cells followed by cell differentiation and cell growth. The group of cells are collectively called tissues and the abnormal growth of tissue in an organism is known as a tumour. The tumours usually develop due to some disturbances in the cell growth and formation of new cells. A tumour is benign (non-cancerous) when the growth is limited and it becomes malignant (cancerous) when it invades the major parts of the body. What is Acoustic Neuroma? Acoustic neuroma is a rare, non-malignant tumour and is also known as Vestibular Schwannoma. It ... Read More

Introduction Food is essential for us to obtain energy to perform metabolic processes. However, the food we eat cannot be assimilated in the form in which it is consumed. It is broken down into simple substances and is absorbed into the circulating fluids by the digestive system. The proper assimilation of nutrients in the food is ensured by its proper digestion and absorption. Proper digestion and absorption can occur only when the digestive system is functioning properly. A proper quantity of nutritional diet and a healthy lifestyle guarantees good health for the digestive system. Unhealthy dietary habits can lead to ... Read More

Transport in plants occurs at three levels: cellular, absorption of water and nutrients and transportation of water and nutrients.The first level that is the cellular transport, wherein the solutes and ions are transferred from one cell to another through Diffusion and Osmosis process.The second level is the absorption of water and nutrients from the soil by the roots. It is a well-known fact that as the surface area increases, the absorption increases.The third level of transport is the transfer of water and nutrients from the root to the top of the plant for around hundred meters of length through a ...

The classification of things while describing and naming them can be understood as Taxonomy. This helps to identify any developmental and experimental work that needs to be done.Simply put, why would anyone mix the shoes in shoe rack with the bed sheets in a cupboard? Taxonomy is our inheritance where we define the places to which they belong. In the same way, it provides an easy to identify the categories of the species so as to have an idea of the existing conditions and to plan necessary measures for the biodiversity conservation.What is Bio-diversity Conservation?Bio-diversity is regarded as the foundation ...

Cryogenic Sleep is the process of freezing a person into a deep sleep for a long time with no supply of food and water. This process was proposed so as to pass time more quickly during the space travel. Cryogenic sleep also stops ageing. This is mostly addressed in science fiction movies.How did this idea develop?During the space travel, the travelers need to take more materials such as food, water, exercise equipment, television etc. as they need to perform exercises to keep themselves healthy and also to keep themselves engaged, as sitting idle for hours would affect them mentally. Now, ... Read More

BioleachingBioleaching is an effective technology for metal extraction from low-grade ores and mineral concentrate. This is a simple process which can be done using microorganisms such as Mesophiles, moderately thermophilic bacteria, Extremophiles. Bioleaching is a part of Bioremediation.This process of Bioleaching was used 3000 years ago while recovering copper from mine waters in the Mediterranean area. From then it has been used, but rarely. Recently about 40 plants are using this method to extract copper, gold, zinc, cobalt, and uranium. The organisms used in this procedure are single-celled and undergo chemosynthetic metabolism. They derive carbon dioxide and oxygen from the ... Read More
