The animals which do not actively control the osmotic condition of their body fluids are

Options

A. Osmoconformers
B. Osmoregulators
C. Hyperosmotic
D. Hypertonic

Answer

To solve the question regarding animals that do not actively control the osmotic condition of their body fluids, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Osmoconformers**: These are organisms that do not actively regulate their internal osmotic environment; instead, they conform to the osmotic conditions of their surrounding environment.
- **Osmoregulators**: These organisms actively control their internal osmotic conditions, maintaining a stable internal environment regardless of external conditions.

2. **Analyze the Options**:
- **Osmoconformers**: As defined, these organisms do not actively control their osmotic balance.
- **Osmoregulators**: These organisms actively regulate their osmotic balance.
- **Hyposmotic**: This term refers to a solution with a lower concentration of solute compared to another solution.
- **Hypertonic**: This describes a solution that has a higher concentration of solute compared to another solution.

3. **Identify the Correct Answer**:
- Since the question asks for animals that do not actively control their osmotic conditions, the correct answer is **osmoconformers**. These animals adapt to the osmotic conditions of their environment rather than actively regulating their internal osmotic state.

### Final Answer:
The animals which do not actively control the osmotic condition of their body fluids are **osmoconformers**.
