Chemical mutagens are far more harzardous than radiations because :-

Options

A. The exposure to chemicals is more prevalent
B. The organism possess protection for radiation but no protection for chemicals
C. The chemically induced matations are more deliterious
D. The chemicals are synthetics

Answer

**Step-by-Step Solution:**

1. **Understanding Chemical Mutagens:**
- Chemical mutagens are substances that can alter the molecular structure of DNA, leading to mutations. They include various chemicals like nitrous acid, alkylating agents, and base analogues.

2. **Analyzing the Options:**
- The question asks why chemical mutagens are considered more hazardous than radiation. We will evaluate each option provided.

3. **Option 1: Exposure of chemicals is more prevalent.**
- This option is incorrect. While chemical mutagens can be present in the environment, the exposure to radiation (from natural and artificial sources) is often more widespread and can affect DNA more readily.

4. **Option 2: Organisms possess protection for radiation but no protection for chemicals.**
- This option is correct. Organisms have evolved mechanisms to repair DNA damage caused by radiation (like natural DNA repair systems), but they lack similar protective mechanisms against many chemical mutagens, making them more hazardous.

5. **Option 3: Chemically induced mutations are more deleterious.**
- This option is incorrect. While chemical mutagens can cause significant damage, radiation can directly affect chromosomes and has higher energy levels that can lead to more severe mutations.

6. **Option 4: Chemicals are synthetic.**
- This option is also incorrect. The mutagenic potential of a substance depends on its ability to affect DNA, not whether it is synthetic or natural.

7. **Conclusion:**
- Based on the evaluation of the options, the correct answer is that organisms possess protection against radiation but lack protection against chemical mutagens, making the latter more hazardous.

**Final Answer:**
Chemical mutagens are far more hazardous than radiations because organisms possess protection for radiation but no protection for the chemicals.
