When we are in a hot room, we sweat profusely. It is a __________means of maintaining homeostasis.

Options

A. morphological
B. physiological
C. behavioural
D. none of these

Answer

To solve the question, we need to fill in the blank with the appropriate term that describes the means by which sweating helps maintain homeostasis in a hot environment. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Homeostasis**: Homeostasis refers to the ability of an organism to maintain a stable internal environment despite changes in external conditions. This includes regulating body temperature and osmotic balance.

**Hint**: Recall the definition of homeostasis and its importance in living organisms.

2. **Identifying the Mechanism**: The question describes a scenario where the body sweats profusely when in a hot room. Sweating is a physiological response that helps cool the body down through the process of evaporative cooling.

**Hint**: Think about how the body responds to heat and what physiological processes are involved.

3. **Categorizing the Response**: The act of sweating is not a morphological adaptation (like fur or feathers) or a behavioral response (like seeking shade). Instead, it is a physiological process that involves the secretion of sweat from sweat glands.

**Hint**: Differentiate between physiological, morphological, and behavioral adaptations.

4. **Filling in the Blank**: Since sweating is a physiological response that helps regulate body temperature and maintain homeostasis, the correct term to fill in the blank is "physiological."

**Final Answer**: When we are in a hot room, we sweat profusely. It is a **physiological** means of maintaining homeostasis.

### Summary:
- Homeostasis is the maintenance of a stable internal environment.
- Sweating is a physiological response to heat.
- The correct term to describe this process is "physiological."
