Solutions

S1.Ans. (b)
Sol. Physical changes are those which are reversible and in such changes no new product (s) are formed. Chemical changes are those which are irreversible and involves formation of new product (s). Burning of magnesium is chemical change in which magnesium oxide is formed 2Mg + O2 = 2MgO

S2.Ans. (c)
Sol. Yellow cakes generally denotes various compounds of uranium like uranium oxides.

S3.Ans. (d)
Sol. Oxides of Sodium readily dissolved in water as it has ionic bond which breaks in water easily other oxides have covalent bond which do not break easily.

S4.Ans. (b)
Sol. Lysosomes are found in cytoplasm of the cell. It acts as the waste disposal system by digesting unwanted or harmful substances in the cytoplasm. Due to this act, they are known as ‘suicide bags’.

S5.Ans. (d)
Sol. Animal and plant cells are eukaryotic cells having cell membrane, cytoplasm, true nucleus, and various organelles (like ER, Golgi complex, ribosomes ((80S) etc.) Bacterial cell is prokaryotic cell in which plasma membrane, cell wall, primitive type of nucleus, ribosomes (70S) etc. present but cell organelles are absent. Animal cells lack cell wall. But there are some structural features which are common in these cells like plasma/cell membrane, cytoplasm and ribosomes.

S6.Ans. (d)
Sol. Chlorenchyma (parenchymatous cells having chloroplasts) participates in photosynthesis. It is present in mesophyll cells of leaves and differentiated into palisade parenchyma and spongy parenchyma.

S7.Ans. (a)
Sol. A vessel element is one of the cell types found in xylem, the water conducting tissue of plants. Vessel elements are typically found in the angiosperms but absent from most gymnosperms such as the conifers.

S8.Ans. (b)
Sol. A person with blood group ‘A’ can donate blood to the person with blood group ‘A’ or ‘AB’ because it has only ‘A’ antigen on RBCs and B-antibodies in plasma. In blood grup AB, there is no antibody in plasma so persons with ‘AB’ group can accept blood from persons with AB as well as the other groups of blood.

S9.Ans. (a)
Sol. Not all proteins are enzymes although a lot of them are. There are proteins that play structural functions (cytoskeletal proteins, keratin, collagen) or transport (haemoglobin, membrane channels).

S10.Ans. (d)
Sol. Vitamin-K plays on essential role in clotting of blood. It act as a cofactor for the enzyme to bind with calcium ions required for activation of coagulation factors such as prothrombin.
