if an osmoconformer animal is placed in sea water then

Options

A. It will develop incocytes to actively absorb the salts from outside
B. it will develop a thick body covber to prevent enter of excess of water
C. It will start passing dilute urine
D. It will change osmolarity of its body fluid.

Answer

### Step-by-Step Solution:

1. **Understanding Osmoconformers**: Osmoconformers are organisms that can maintain their internal osmotic pressure similar to their external environment. They do not actively regulate their internal osmolarity but rather allow it to fluctuate with the surrounding water conditions.

2. **Placement in Seawater**: When an osmoconformer is placed in seawater, the osmolarity of the seawater is typically higher than that of the internal fluids of the osmoconformer. Seawater has a high concentration of salts (solutes), which creates a hyperosmotic environment.

3. **Osmoregulation Response**: In response to being in a hyperosmotic environment, the osmoconformer will adjust its internal osmolarity to match that of the seawater. This means that the osmoconformer will not need to actively absorb salts or develop any additional structures to prevent water loss, as it is already adapted to match its osmotic pressure with that of the seawater.

4. **Minimization of Osmotic Gradient**: The osmoconformer will minimize the osmotic gradient between its internal fluids and the seawater. This is crucial because a large osmotic gradient could lead to excessive water loss from the organism's body.

5. **Urine Production**: Since the osmoconformer is already matching the osmolarity of the seawater, it will not produce dilute urine. Instead, it will likely produce urine that is isotonic to its internal fluids, thus maintaining osmotic balance.

6. **Conclusion**: Therefore, the osmoconformer will adjust its body fluid osmolarity to match that of the seawater, resulting in no need for adaptations like developing enocytes or a thick body cover. It will not pass dilute urine, as its internal osmolarity will be similar to that of the seawater.
