An insulator or neither. The water inside of the sponge is what would conduct electricity.

The body of a sponge is covered in tiny openings called pores. These pores allow water to flow in and out of the sponge, which helps the sponge filter out food particles and oxygen from the surrounding water.
You could first soak the sponge in water, then use the standard method of measuring irregular objects: fill a graduated cylinder with 100 mL of water, then drop in the wet sponge and see how much the water level rises.
It would sink.
Top opening of a sponge is called osculum . it is used to expel water out .
No
neither a sponge would
Per the equivalent mass area covered by both cotton and sponge, the cotton would be more absorbent because it offers lessresistance to moisture. its shape would actually change because of complete saturation and displacement while the sponge would maintain its original shape and expand once moisture is absorbed.
The structural adaptations you would notice on a cactus are the spines on it. The spines are there so they don't loose water.
