i) Required for solubilization of chemicals and several biochemical reactions like hydrolytic digestion of polymeric nutrients, photosynthesis, etc. ii) Important for the working of macromolecules, as a good ionizer, transport of materials, etc. iii) Acts as a habitat for hydrop..

Maintains osmotic pressure and viscosity of the blood Helps in transport of various substances like the hormones, enzymes, etc. Acts as a protein reservoir Helps in clotting of blood Helps in regulating body temperatur..

This process is much faster and requires energy. A membrane pump operates across the cell membranes which transports the nutrients from the lumen of the intestine into the cells. This transport occurs with the help of ATP molecules. The carrier proteins in the membrane act..

Lipids perform several important functions in biosystems. Phospholipids are the constituents of cell mebrane and regulate membrane permeability. Phospholipids are also used as detergents to emulsify fat for transport within the body. They act as cellular metabolic regul..

The growth of plants is regulated by certain chemical substances, which are synthesized by the plant in very small quantities. These substances are formed in one tissue or organ of the plant and are then transported to other sites where they produce specific effects on growth and developm..

Digestion starts at the mouth with the mandibles and the maxillae chewing the food. It is also acted upon by enzymes of salivary juice, the salivary carbohydrases which partially digest the food. The food is then swallowed with the help of lubrication provided by the salivary juice. Th..

Following are the chief uses of ammonia: 1) Ammonia is used in the industrial preparation of nitric acid by Ostwald's process. 2) Fertilisers, such as ammonium sulphate, ammonium nitrate, ammonium phosphate, urea etc. are manufactured with the help of ammonia. 3) It is used in the manufacture of ot..

Digestion starts at the mouth with the mandibles and the maxillae chewing the food. It is also acted upon by the salivary carbohydrases which partially digests the food. The food then enters the oesophagus and then into the crop for temporary storage. The food is then passed into the giz..

The renal artery enters the kidney at the notch on the concave side called the hilus renalis. As it is a branch from the aorta it brings oxygenated blood carrying toxic nitrogenous wastes into the kidneys. Renal Vein The renal vein drains away deoxygenated blood which is free of toxic subs..
