Solutions

S1.Ans. (c)
Sol. A person containing O+ blood group does not possess any antigen to elicit any antibody reaction in the acceptor. Thus, a person with O+ is the universal donor. AB+ on the other hand is a universal acceptor.

S2.Ans. (d)
Sol. Scattering of light takes place in colloidal solution. This phenomenon is called Tyndall effect. The path of the light beam illuminates by scattering of light.

S3. Ans. (d)
Sol. Telophase is the stage where cytokinesis usually occurs in animals, which means the cell divides into two daughter cells and is identical to each other.

S4. Ans. (a)
Sol. A vector quantity is one which has both magnitude and direction. Velocity has both magnitude and direction so it is a vector quantity.

S5. Ans. (a)
Sol. Supersonic speed is a rate of travel of an object that exceeds the speed of sound. For objects travelling in dry air of a temperature of 20°C at sea level, this speed is approximately 343 m/s.

S6. Ans. (d)
Sol. Vitamin D is a steroid hormone, a group of fat-soluble secosteroids that plays a vital role in calcium and phosphate absorption. Vitamin D also enhances intestinal absorption of calcium, iron and magnesium, while vitamin A deficiency causes night blindness, vitamin C deficiency causes scurvy and vitamin B deficiency causes beriberi.

S7.Ans. (d)
Sol. Tube light is filled with mercuric oxide and argon gas where mercuric oxide is used to emit UV light while argon gas is used to provide an inert atmosphere within the tube.

S8. Ans. (c)
Sol. Brass is an alloy of copper and zinc. The proportions of zinc and copper can vary between different types of brass alloys having different mechanical and electrical properties.

S9. Ans. (b)
Sol. The viscosity of the liquid tends to decrease with the increase in temperature. The temperature effect on viscosity is different for liquid and gases.

S10. Ans. (b)
Sol. Different types of WBCs or white blood cells help in fighting against infectious agents. These are named as macrophages, lymphocytes etc.
