Solutions

S1.Ans. (d)
Sol. Calcium activates enzymes, is a structural component of cell walls, influences water movement in cells and is necessary for cell growth and division. Potassium helps in energy flow, manganese is involved in enzyme synthesis and phosphorus makes up backbone of genetic materials like DNA and RNA.

S2.Ans. (b)
Sol. Collenchymas provides malleability and flexibility to certain parts of the plants. Parenchyma is considered to be the soft tissue which makes most of the cell and sclerenchyma is the dead tissue which makes up fibre and provides rigidity to the cell.

S3.Ans. (c)
Sol. Blood plasma cells form 55 – 60% by volume of blood. Antibodies and some other substances such as lysozyme and properdin always occur in the plasma. They serve to destroy bacteria, viruses and toxic substances that may enter into the blood from outside or from body tissues.

S4.Ans. (b)
Sol. A long jumper runs before jumping to maintain momentum. This helps in jumping higher and longer because of inertia of motion gained due to the motion.

S5.Ans. (b)
Sol. Ferns, a group under pteridophytes have large number of chromosomes e.g., Ophioglossum reticulatum has 2n=1260, highest known in all life forms.

S6.Ans. (b)
Sol. When two equal and opposite forces act at the same point, then resultant forces is double than either of the forces or two equal and opposite parallel forces not acting along the same line form a couple.

S7. 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.

S8. Ans. (b)
Sol. Different types of WBCs or white blood cells help in fighting against infectious agents. These are named as macrophages, lymphocytes etc.

S9.Ans. (d)
Sol. Nitrochloroform is a broad-spectrum antimicrobial which is used as a fungicide, herbicide, insecticide and nematicide. It is also known as Chloropicrin.

S10.Ans. (a)
Sol. Collar cells occurs in sponges and located at the anterior end of each choanocyte.
