Solutions
S1.Ans. (b)
Sol. If a rock is brought from the surface of the moon to the earth, its weight will change but not its mass. Mass is a invariant physical quantity whereas weight of a body (w = mg) is variable as the value of acceleration due to gravity (g) changes.
S2.Ans. (c)
Sol. The two points in the same horizontal line do not have equal pressure if the liquid is accelerated horizontally. The free surface of oil is inclined to the horizontal with larger depth at the rear end as the oil tanker is moving forward with uniform acceleration.
S3.Ans. (a)
Sol. The charged carbon atom in a carbocation is a “sextet”, i.e. it has only six electrons in its outer valence shell instead of the eight valence electrons that ensures maximum stability (octet rule). Therefore carbocations are often reactive, seeking to fill the octet of valence electrons as well as regain a neutral charge.
S4.Ans. (c)
Sol. The smooth endoplasmic reticulum (smooth ER) is continuous with the rough ER but has few or no ribosomes on its cytoplasmic surface. Functions of the smooth ER include: Synthesis of carbohydrates, lipids, and steroid hormones.
S5.Ans. (c)
Sol. One of the key organelles involved in digestion and waste removal is lysosome. Lysosomes are organelles that contain digestive enzymes.
S6.Ans. (b)
Sol. Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin, they are alkaline (basic pH) proteins, and their positive charges allow them to associate with DNA. They are found inside the nucleus of eukaryotic cells.
S7.Ans. (b)
Sol. Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose and chitin, respectively. The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan.
S8.Ans. (b)
Sol. The protein inside red blood cells that carries oxygen to cells and carbon dioxide to the lungs is haemoglobin. Oxygen enters the blood from the lungs and carbon dioxide is expelled out of the blood into the lungs. The blood serves to transport both gases. Oxygen is carried to the cells. Carbon dioxide is carried away from the cells.
S9.Ans. (b)
Sol. As scuba diver ascends towards the water surface, water pressure decreases, so according to Boyle’s law air in his lungs expands to occupy a greater volume. Which increase the chances of bursting the lungs.
S10.Ans. (a)
Sol. Fountain pen uses capillary action in addition to gravity for flow of ink.
