Hi all...I am new to this forum
These r some questions I encountered in various sample papers
Biology
1. Give an example of an anabolic and catabolic process
2. How is Energy provided by the oxidation of glucose?
3. What is double circulation?
4. What is CO2compensation point?
5. Is the movement of sunflowers a tropic movement?
6. Why does sugar taste differently when our Nose is blocked?
7. What is an angiosperm?
8. What is the function of petals and sepals?
9. What are the advantages of seed formation in plants?
10. Do variations that confer an advantage to an individual organism survive in a population? [Ncert Exercises Question]
11. Can evolution occur in humans?
12. How do Mendel's law of Inheritance Work in a***ually reproducing organisms?
Physics
1. What are the various ratings of a fuse wire? Can we us only these in the numericals?
2. Current passes through a circular loop in a clockwise direction. Determine the direction of the magnetic field inside and outside the loop? [NCERT In text Question]
3. Can hydrogen be considered a cleaner fuel than CNG? Why /Why not? [NCERT Question]
4. Compare the power used in the 2 ohm resistor in each of the following circuits
a. A 6V battery in series with 1 ohm and 2 ohm resistors
b. A 4V battery in parallel with 12 ohm and 2 ohm resistors?
Chemistry
1. What is the colour of Lead Oxide?
2. In the reaction when to show the disassociation of a base into ions, why is H2O placed on the arrow?
3. What are the colours seen in Methyl Orange on acidic and basic media?
4. What are the products formed when water is added to baking powder?
5. Why can't copper used to galvanize iron?
6. Do non metals also form neutral oxides? Refer to Summary on Pg. 56 of textbook.Pls give an example
7. Is ethanol acidic or basic?
8. A substance 'A' is produced by reacting 'B' in the presence of phosphoric acid. ’A' burns in air with a blue flame to form carbon dioxide and water. Identify A and B.
