Answer:
Gabriel's horn
Explanation:
What the question is asking for is a 3-dimensional shape that has a lot of surface area and only a little volume. The first thing I thought of was a geometric figure called Gabriel's Horn. A quick search on Wikipedia will explain better than I can, but basically it has infinite surface area but finite volume. You probably couldn't test the shape in any experiment, though, since it's only theoretical and can't exist in real life.
Let me know if I can explain anything in a clearer way!

The correct answer is 4. The nervous tissue is formed by various types of nerve cells that create electrical impulses but also participate in the transportation of these impulses throughout the body. These electrical impulses act as signals and carriers of information around the body. Therefore, the nervous tissue is the one responsible for signal conduction in the body.
