Which of the following human disease can be prevented by the same hormone which brings about metamorphosis in frogs ?

Options

A. diabetes
B. anaemia
C. goitre
D. rickets

Answer

**Step-by-Step Solution:**

1. **Identify the Hormone Responsible for Metamorphosis in Frogs:**
- The hormone responsible for the process of metamorphosis in frogs is **thyroxine**. This hormone facilitates the transformation of a tadpole into an adult frog, which includes various morphological changes.

2. **Understand the Role of Thyroxine in Humans:**
- In humans, thyroxine plays a crucial role in regulating metabolism and is essential for normal growth and development. It is produced by the thyroid gland and requires iodine for its synthesis.

3. **Identify the Disease Related to Thyroxine Deficiency:**
- A deficiency in thyroxine leads to a condition known as **goiter**. Goiter is characterized by the enlargement of the thyroid gland, which occurs when there is insufficient iodine in the diet, leading to decreased production of thyroxine.

4. **Differentiate Between Other Diseases Mentioned:**
- Other diseases mentioned in the context (like diabetes, anemia, and rickets) are caused by different deficiencies:
- **Diabetes** is caused by a deficiency of insulin.
- **Anemia** is due to iron deficiency.
- **Rickets** is related to a deficiency of vitamin D.
- None of these diseases are linked to thyroxine.

5. **Conclusion:**
- Therefore, the human disease that can be prevented by the same hormone that brings about metamorphosis in frogs is **goiter**.

**Final Answer: Goiter**
