Answer: The answer is B. Hydrogen.
Explanation:
I think that the tectonic plates would shift towards each other. This creates what is known as a convergent boundary. If the plates moved away, then this would be known as a divergent boundary. If it is wrong, I am terribly sorry. I did this question on a quiz before, and I think I got it right. It was in 8th grade though, so... two years ago.
The mechanism in a cell's connected section of the membrane that detects chemical signals is i.e. structure labelled B in the diagram. Thus, the correct option is D.
<h3>
What are receptors?</h3>
Receptors, which are large proteins that can be found within or outside of cells, are the components of a cell that are in charge of identifying chemical signals.
Whereas plasma membrane junctions interact with surface proteins found inside cells during cell to cell signaling.
Thus, it follows that the structure designated B in the diagram is the one that serves as a chemical signal receptor.
