Laws of Heredity - The principles of inheritance are termed Mendel's theory. The laws of heredity are- (i) Law of segregation (ii) Law of Independence Assortment (iii) Law of Paired Factors (iv) Law of Dominance 2.  Lamarck theory - The theory states that the effective and ineffective use of organs bring some changes in the structure of living bodies. 3. Archimedes Principle  -When an object is (Wholly or partially) immersed in a liquid, it experiences a buoyant force (upthrust) which is equal to the weight of the liquid displayed by the object. Buoyant force for (upthrust)= weight of the liquid displaced by that object. Avograde’s Law: Equal volumes of all gases under the same conditions of temperature and pressure c...
