No. He is not correct. Both crow and dragonfly have the same function of flying with wings But it.s origin (basic structure) is different. Dragon fly wing the membranous extension. But wing of the crow is the modification of forelimb.

Rajesh went with his family for Bombay tour. The whole family was waiting for the arrival of train. Rajesh was standing near the pavement looking for the train. His family members were seated. When train came near Rajesh, he felt pulled by the train with drag, but suddenly his grandma saved him from falling. Rajesh was shocked and nervous due to this incident. Why Rajesh experienced this pull ? Give the expression for Bernoulli's theorem.

Read the following paragraph and answer the questions given below: Dmitri Ivanovich Mendeleev was the first to classify elements on the basis of their fundamental property, the atomic mass, and also on the similarity of chemical properties. When Mendeleev started his work, 63 elements were known. He examined the relationship between the atomic masses of the elements and their physical and chemical properties. Among chemical properties Mendeleev concentrated on the compounds formed by the elements with oxygen and hydrogen. He selected hydrogen and oxygen as they were very reactive and formed compounds with most elements . The formulae of the hydrides and oxideswere treated as one of the basic properties of an element for its classification. He sorted out the elements with similar properties and pinned the cards together on a wall. He observed that most of the elements got a place in the periodic table and were arranged in the order of their increasing atomic masses. It was also observed that there occurs a periodic recurrence of elements with similar physical and chemical properties . On this basis Mendeleev formulated a periodic law which states that "The properties of the elements are the periodic function of their atomic masses". What was the basis of Mendeleev's classification?
