S1. Ans.(d)
Sol. Hemoglobin is the iron containing oxygen transport metalloprotein in the red blood cells. 
S2. Ans.(a)
Sol. Bakelite is used for wire insulation. Brake pads and related automobile components and industrial electrical related application. 
S3. Ans.(b)
Sol. Transpiration in the process of water movement through a plant and its evaporation from serial part, such as from leaves, stems and flowers.
S4. Ans.(b)
Sol. According to 10% Law, Plants have 20,000 J energy available. Plants transferred their 10% energy to deer i.e. 20,000 * 10/100 = 2000 J Deer received 2000 J energy from the plants and now it transfer 10% energy of itself to lion. 2000 ×10/100= 200 J Hence, lion will have 200 J energy from deer. 
S5. Ans.(a)
Sol. Metals lying low in the reactivity series are obtained by just heating their oxides alone.
S6. Ans.(c)
Sol. Distillation is a process of separating component substances from liquid mixtures through vaporization and condensation. Water can be distilled to remove impurities. 
S7. Ans.(b)
Sol. if diameter is doubled then radius is also doubled, i.e., the distance of the object from the centre doubles. We know that weight is inversely proportional to the square of the distance, so weight reduces to one fourth its original value.
S8. Ans.(d)
Sol. When a conductor carrying a current is placed in a magnetic field, the conductor experiences a magnetic force. The direction of this force is always right angles to the plane containing both the conductor and the magnetic field, and is predicted by Fleming’s Left-Hand Rule.
S9. Ans.(c)
Sol. On the moon the escape speed is low thus the faster moving atom escape overtime. 
S10. Ans.(b)
Sol. constant speed.
