Chemical Coordination in Animals Introduction
Introduction - A cell, a tissue or an organ, which secretes certain useful chemical compounds required for a particular function, is called a Gland. Thus glands, which are seretory in functions, can be of two types, namely (i) Exocrine glands that have ducts or the ope..
Periodic Properties and their Variations Introduction
Introduction - We have already studied the 'Periodic Classification of Elements' in standard ninth. We know that the periodic table is the arrangement of Elements into periods and groups on the basis of their electronic configuration. The Modern Periodic Table follows the 'Modern Periodic..
Excretion and Osmoregulation Introduction
Introduction - The steam engine uses the power generated from steam pressure to move. Coal is used in furnaces to heat water in the boiler to generate steam. Steam pressure makes the wheels of the engine move. As coal is burnt, smoke is emitted and ash is left behind in the furnace. Smoke..
Organic Compounds Oxygen - I Introduction
Introduction - Alcohols, phenols, ethers, aldehydes, ketones and carboxylic acids are compounds with functional groups containing oxygen. An alcohol contains one or more hydroxyl (OH) groups(s) attached to aliphatic carbon atom(s). For e.g., ethyl alcohol formula CH 3 , CH 2 , O..
Animal Histology Introduction
Introduction - A tissue is a group of cells having a common origin, similar structure and performing a common function. Tissues are characteristic of advanced multicellular animals, commonly called as eumetazoans. They are true multicellular animals where the body cells aggregat..
