Match List I with List II Choose the correct answer from the options given below:LIST I (Hazardous substance) LIST II (Specific effect) A. Neurotoxins I. Substances that cause cancer. B. Mutagens II. Substances that attack nerve cells. C. Teratogens III. Substances that damage or alter genetic material (DNA) in cells. D. Carcinogens IV. Substance that cause abnormality during embryonic growth and development.
A-II, B-III, C-IV, D-I
This is a match-the-following question on categories of hazardous substances classified by their specific biological effect. Each item in List I must be matched with its precise mechanism of harm in List II:
| Hazardous substance (List I) | Specific effect (List II) |
|---|---|
| Neurotoxins | Substances that attack nerve cells — they interfere with the structure or function of the nervous system, disrupting neurotransmission. |
| Mutagens | Substances that damage or alter genetic material (DNA) in cells — causing mutations that can be passed on when the cell divides. |
| Teratogens | Substances that cause abnormality during embryonic growth and development — exposure during pregnancy can lead to birth defects. |
| Carcinogens | Substances that cause cancer — they promote uncontrolled cell growth by damaging DNA or disrupting cellular regulation. |
Matching each pair on this biological basis gives: neurotoxins attack nerve cells, mutagens damage or alter DNA, teratogens cause developmental abnormality in embryos, and carcinogens cause cancer. This is exactly the correct match among the given combinations.
