A researcher places sender cells on one side of a gel that slows diffusion and receptor-bearing target cells on the other side. The target cells respond after a delay. What is the best interpretation?
A
The target cells must have responded before the signal was released.
B
A released chemical signal likely diffused through the gel until target-cell receptors detected it.
C
The sender cells must have passed cytoplasm directly through the gel into target cells.
D
The gel converted the target cells into sender cells by adding chromosomes.
