The correct Answer is:
To determine how many of the listed features are applicable to hormones, we will analyze each feature one by one. ### Step-by-Step Solution: 1. **Feature i: The non-nutrient chemicals** - Hormones are indeed classified as non-nutrient chemicals. They are not used as a source of energy or building blocks for the body, but instead, they serve as signaling molecules that regulate various physiological processes. - **Conclusion:** This feature is applicable to hormones. 2. **Feature ii: Intracellular messengers** - Hormones can act as intracellular messengers. They bind to specific receptors on target cells and initiate a response within those cells. This signaling can occur through various pathways, leading to changes in cell function. - **Conclusion:** This feature is applicable to hormones. 3. **Feature iii: Released in blood or open spaces** - Hormones are primarily released into the bloodstream, where they travel to their target organs or tissues. They are not typically released into open spaces; rather, their action is mediated through the circulatory system. - **Conclusion:** This feature is not applicable to hormones. 4. **Feature iv: Produced in trace amounts** - Hormones are produced in very small quantities, often measured in micrograms or nanograms, yet they can have significant effects on the body. This characteristic is a defining feature of hormones. - **Conclusion:** This feature is applicable to hormones. ### Summary of Findings: - Applicable features: i, ii, iv - Not applicable feature: iii ### Total Count of Applicable Features: - There are **three features** (i, ii, iv) that are applicable to hormones. ### Final Answer: - The answer is **3**.
