Secretion of ductless glands are known as

Options

A. Hormones
B. Pheromones
C. Enzymes
D. Mucoids

Answer

To answer the question "Secretion of ductless glands are known as," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Secretions**: The question presents four options: endoplasmic hormone, pheromones, enzymes, and mucoids. We need to analyze each option to determine which one is related to ductless glands.

2. **Analyze Each Option**:
- **Mucoids**: These are secretions from mucosal glands or membranes, not ductless glands.
- **Enzymes**: These are biocatalysts that facilitate biochemical reactions but are not specifically secreted by ductless glands.
- **Pheromones**: These are chemical signals used for communication between organisms of the same species and are not secreted by ductless glands.
- **Hormones**: These are chemical messengers secreted by endocrine (ductless) glands into the bloodstream.

3. **Conclusion**: Since hormones are specifically secreted by ductless glands, the correct answer to the question is "hormones."

### Final Answer:
The secretion of ductless glands is known as **hormones**.
