Choose the correct answer from the options given below :
| List - I (compound) |
List - II (effect/affected species) |
||
|---|---|---|---|
| (a) | Carbon monoxide | (i) | Carcinogenic |
| (b) | Sulphur dioxide | (ii) | Metabolized by pyrus plants |
| (c) | Polychlorinated biphenyls | (iii) | haemoglobin |
| (d) | Oxides of Nitrogen | (iv) | Stiffness of flower buds |
Choose the correct answer from the options given below :
(a) - (iii), (b) - (iv), (c) - (i), (d) - (ii)
(a) - (iv), (b) - (i), (c) - (iii), (d) - (ii)
(a) - (i), (b) - (ii), (c) - (iii), (d) - (iv)
(a) - (iii), (b) - (iv), (c) - (ii), (d) - (i)
Explanation
A. If haemoglobin binds CO, it prevents the binding of O2 to haemoglobin due to the competition for same binding sites.
B. Higher conc. SO2 in air can cause stiffness of flower buds.
C. Polychlorinated biphenyls are carcinogenic (cancer causing) in humans as well as animals.
D. Certain plants, e.g. pinus, Juniparus, quercus, pyrus and vitis can metabolise nitrogen oxides. Hence, the correct match is
(a) - (iii), (b) - (iv), (c) - (i), (d) - (ii)Comments (0)
