Water is constantly supplied to the body through food and fluid intake. It is expelled out as urine while some water is lost by perspiration through the skin. The maintenance of water balance is essential for carrying on life processes. Over accumulation of water can lead to edema, while excessive loss or very limited intake […]

Introduction Evolution is a complex process. Studying different organisms (both living and extinct) with respect to their physical, and functional characters for a long duration makes an understanding of how present-day species have evolved. Sometimes the environment and living conditions force organisms to acquire new features essential for them. Without which, the particular organism can […]

Define ACTH ACTH is an acronym for an adrenocorticotropic hormone which is produced and released by the anterior pituitary gland. It is also referred to as corticotropin. Its functions involve stimulating the production of hormones from the adrenal cortex, specifically glucocorticoids. How is ACTH synthesised? Overview The synthesis of ACTH is triggered when the pituitary […]

Introduction All living organisms can produce new individuals like themselves and their cells have a nucleus containing chromosomes. In humans, there are 23 pairs of chromosomes, each chromosome has thousands of genes. A gene can carry the information that determines the character or trait being transmitted from the parent to offspring and creates the identity […]

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 […]

Reproduction is the reason for life’s continued existence on the face of Earth. Every organism needs to be able to reproduce so that it can classify as a living being. Even viruses, whose living nature has been debated for decades, can reproduce in the host’s body. The molecular basis of life, i.e., the DNA, needs […]

Survival of an organism greatly depends on the ability of that organism to adjust to the changes in its environment. Acclimatization and adaptation are two ways by which an organism survives in the changing environment. Acclimatization takes place in a short period of time and causes temporary changes in the body which ensures survival. On […]

Human beings are complex organisms and they have various nutritional needs in order to maintain proper functioning of the body. To meet this need, they consume food. However, the food consumed by them cannot be directly assimilated into the cells. Prior to assimilation, these complex food molecules should be broken down into simpler substances by […]
