<span>The answer is False. Buffers ensure that the cell environment remains at a constant pH even with the addition of small
amounts of acid or base. This ensures
that the cell environment is always optimum for biological processes such as
the functioning of enzymes, and most other proteins, that require a particular
pH to maintain their integrity</span>
Answer:
When cells communicate by the signaling process, one cell produces a <u><em>signaling molecule</em></u> that must be received by the <u><em>signal receptor </em></u>on or in the responding cell.
