 Excretion:In plants Excretion, the process by which animals and plants rid themselves of waste products and of the nitrogenous by-products of metabolism. Through excretion organisms control osmotic pressure—the balance between inorganic ions and water—and maintain acid-base balance. The process thus promotes homeostasis, the constancy of the organism’s internal environment. Plants have no special … Read more Excretion

 Blood group Blood group is an inherited feature on the surface of the red blood cells. A series of related blood types constitutes a blood group system, such as the Rh or ABO system. The frequencies of the ABO and Rh blood types vary from population to population. In the US, the most … Read more Blood Group

 Food bio technology Biotechnology is defined in accordance with the Convention on Biological Diversity, i.e. “any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use” Biotechnology as applied to food processing in most developing countries makes use of microbial inoculants to … Read more Food Bio Technology

 Respiratory quotient: Carbohydrates, fats and protein The respiratory quotient (or RQ or respiratory coefficient), is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. It is calculated from the ratio of carbon dioxide produced by the body to oxygen consumed by the body. Such measurements, … Read more Respiratory Quotient

 External Respiration One method for obtaining oxygen from the environment is through external respiration or breathing. In animal organisms, the process of external respiration is performed in a number of different ways. Animals that lack specialized organs for respiration rely on diffusion across external tissue surfaces to obtain oxygen. Others either have organs specialized … Read more Types Of Respiration

 Blood makes up about 8% of the human body weight. It contains erythrocytes, leucocytes, thrombocytes (platelets) and plasma. The volume percentage of all blood cells in the whole blood is about 45% of adults (hematocrit). The rest consists of liquid plasma (e.g. water, plasma proteins, electrolytes etc.). The blood is composed of: Plasma Plasma … Read more Composition And Function Of Blood
