  Classification of caudal fin  The caudal fin, or tail fin, in fish can be classified into different types based on its shape and structure. The caudal fin, or tail fin, is a critical anatomical feature in fish, serving various functions essential for survival. Here are the primary functions of the caudal fin: Propulsion : The caudal fin is the main propulsive force for most fish, allowing them to swim forward. By moving the fin side to side, fish generate thrust that propels them through the water. Different types of caudal fins provide varying degrees of speed and power. Maneuverability : The shape and flexibility of the caudal fin allow fish to make precise movements, including quick turns and sudden stops. This maneuverability is crucial for avoiding predators, catching prey, and navigating complex environments like coral reefs or dense vegetation. Stability: The caudal fin helps maintain balance and stability in the water, preventing the fish from pitching (tilting forwa...

Ganga Action Plan I (GAP I)     Ganga Action Plan I (GAP I) was the first major initiative taken by the Government of India to clean and restore the Ganga River, one of the most important and sacred rivers in the country. Launched in 1985, this plan was a response to the alarming levels of pollution affecting the Ganga due to untreated sewage, industrial effluents, and other waste discharges from various sources along its course. Key Aspects of Ganga Action Plan I: Objective: The primary objective of GAP I was to improve the water quality of the Ganga River to acceptable standards by preventing pollution from entering the river. Initially, the goal was to reduce pollution levels, but in a 1987 meeting led by Prof. M. G. K. Menon, the objective was revised to restoring the river's water quality to the "Bathing Class" standard. The Bathing Class standard includes the following criteria: Bio-Chemical Oxygen Demand (BOD): ...
