The correct Answer is:
To solve the question regarding Sam's abnormal growth, we need to identify the endocrine gland and hormone responsible for his condition. Here’s a step-by-step breakdown: ### Step 1: Understanding the Symptoms - Sam is described as being very tall and giant for his age, and he appears older than his elder brother John. This suggests a condition related to excessive growth. **Hint:** Look for conditions associated with abnormal growth patterns. ### Step 2: Identifying the Condition - The symptoms point towards a condition known as "gigantism," which occurs when there is an excess of growth hormone during childhood. This leads to abnormal increases in height and size. **Hint:** Consider the role of growth hormone in growth and development. ### Step 3: Identifying the Endocrine Gland - The gland responsible for producing growth hormone is the pituitary gland. This gland is located at the base of the brain and is crucial for regulating various hormones, including growth hormone (GH). **Hint:** Recall which gland is often referred to as the "master gland" due to its role in hormone regulation. ### Step 4: Identifying the Hormone - The hormone responsible for the excessive growth seen in Sam is growth hormone (GH). An overproduction of this hormone leads to conditions like gigantism in children. **Hint:** Think about which hormone is directly involved in growth and development. ### Step 5: Conclusion - Based on the analysis, the likely cause of Sam's abnormal growth is the pituitary gland producing excess growth hormone. **Final Answer:** The endocrine gland is the **pituitary gland**, and the hormone is **growth hormone**. ### Summary of the Answer - **Endocrine Gland:** Pituitary Gland - **Hormone:** Growth Hormone
