Assertion (A): Hormones must be released in precise amounts for proper...
- The Assertion is correct because hormones indeed need to be released in specific quantities to maintain homeostasis and ensure proper bodily functions.
- The Reason is also correct as feedback mechanisms, such as those involving insulin and blood sugar levels, play a critical role in monitoring and adjusting hormone secretion.
- Furthermore, the Reason directly explains the Assertion, as these feedback systems are essential for achieving the precise hormone levels necessary for physiological balance.
- Therefore, both statements are true, and the Reason provides the correct explanation for the Assertion.

Assertion (A) Explained
Hormones are chemical messengers that play a crucial role in regulating various physiological processes in the body. Their release must be precise in quantity to maintain homeostasis, which is the body's ability to maintain a stable internal environment despite external changes. An imbalance in hormone levels can lead to various health issues, ranging from metabolic disorders to growth problems.
Reason (R) Explained
The body employs feedback mechanisms to monitor and adjust hormone levels. These mechanisms involve sensors that detect changes in the internal environment and trigger the release or inhibition of hormones accordingly. For example, the hypothalamus and pituitary gland work together to regulate hormone production through negative feedback loops, ensuring that hormone levels remain within optimal ranges.
Relationship Between A and R
- Both Assertion and Reason are true.
- The Reason directly explains why the Assertion is true: feedback mechanisms ensure that hormones are released in precise amounts based on the body's current needs.
Conclusion
Since the Reason effectively explains the Assertion, the correct answer is option 'A'. Understanding this relationship emphasizes the importance of hormonal regulation and the sophisticated systems in place that maintain physiological balance in the body.
