The correct Answer is:
To determine which statement about hormones is incorrect, let's analyze each option step by step. ### Step-by-Step Solution: 1. **First Statement: Hormones are chemical acts as intercellular messengers.** - **Analysis:** This statement is correct. Hormones are indeed chemical substances that facilitate communication between cells, acting as intercellular messengers. They help regulate various physiological processes in the body. 2. **Second Statement: They are non-nutrient chemicals.** - **Analysis:** This statement is also correct. Hormones are classified as non-nutrient chemicals because they do not provide energy or serve as building blocks for cellular structures. Instead, they function primarily in signaling and regulation. 3. **Third Statement: They are always produced in trace amounts.** - **Analysis:** This statement is correct as well. Hormones are typically produced in very small quantities and are released into the bloodstream only when needed. This allows for precise regulation of bodily functions. 4. **Fourth Statement: They are species-specific chemicals.** - **Analysis:** This statement is incorrect. While hormones can be specific to certain functions within a species, they are not species-specific in the sense that different species can share the same types of hormones. For example, both humans and lions produce hormones like insulin and adrenaline. ### Conclusion: The incorrect statement regarding hormones is **option 4**: "They are species-specific chemicals." ---
