Match List - I with List - II :
| 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 :
Solution
<p>A. If haemoglobin binds CO, it prevents the binding of O<sub>2</sub>
to
haemoglobin due to the competition for same binding sites.</p>
<p>B. Higher conc. SO<sub>2</sub>
in air can cause stiffness of flower buds.</p>
<p>C. Polychlorinated biphenyls are carcinogenic (cancer causing) in
humans as well as animals.</p>
<p>D. Certain plants, e.g. pinus, Juniparus, quercus, pyrus and vitis
can metabolise nitrogen oxides. Hence, the correct match is </p>
(a) - (iii), (b) - (iv), (c) - (i), (d) - (ii)
