CBSE Board Exam 2022 Science Question Papers (Series 1,2,3,4) can be had from the attachments below.
Some questions asked for the exam are:
1. In a cross between red coloured and white coloured flowers, when plantswith red coloured flowers of FI generation were self pollinated, plants of F2 generation were obtained in which 75% of plants were with red flowers and 25% plants were with white flowers. Explain the inheritance of traits in the above cross with the help of a flow chart only along with the ratio of plants obtained.
2. Differentiate between binary fission in Amoeba and binary fission in Leishmania.
How does reproduction take place in malarial parasite ?
3. What are trophic levels ? Why are autotrophs considered to be at the first trophic level of all food chains ? State the reason for limited number of trophic levels in nature.
4. What is a Solenoid ? Draw the pattern of the magnetic field lines around a current carrying solenoid. Mark on the pattern the region where the magnetic field is uniform.
5. How do Mendel’s experiments show that the traits are inherited
independently ? Explain.
