Channel Link Biology:- • / @lecturermbilalchaudhary6369 • Lec:- Muhammad Bilal Chaudhary (M. Phil Biology) • Govt. Postgraduate College Railway Road Shakargarh. Distt Narowal Punjab Pakistan. • Channel Link Physics:- • Physics Preparation (M. Phil Physics Quaid-i-Azam University Islamabad) • / @physics-preparation • In this video you learn about. • Acid Rain:- • Sulphur dioxide and nitrogen dioxide emitted in the air during the burning of fossil fuels. Combined with water vapours in the atmosphere forms acids e.g. Days later and often hundreds or thousands of kilometerts away from the source the acid falls either dissolved in rain or as microscopic dry particles (acid deposition). • This is also due to the overloading of nitrogen and sulphur cycle. Acid rain damages life in lakes, farms and forests. Acid water draining though the soil washes out essential nutrients such as calcium and potassium. It also kills decomposers and microorganism. Plants poisoned and deprived of nutrients become weak and vulnerable to infection and insect attack. • Stone monuments like “Taj Mahal” are being eroded due to “stone cancer” by acid rains. • Introduction of Osmoregulation. Water relation in cell. Osmoregulation in plants. • 1.Hydrophytes • 2.Mesophytes • 3.Xerophytes • Each and every points also discuss with you. you must watch this video and share. some other important topic also discuss with you. like this.
