Answer:
D. Each receptor triggers one particular type of cell behavior, for example, activating gene expression.
Explanation:
- Each extracellular signal molecule can induce different responses depending on the target cell.
- Lipophilic receptors diffuse or carried across the cell's plasma membrane and bind to an intracellular receptor. For example steroid hormones are transported via carrier proteins.
- Some signalling molecules only induce response from specific cells.
- A single receptor can be activated by different signal molecules.
The question is incomplete as it lacks the group of choices required to answer. However, the correct answer on the basis of general information and knowledge is as follows:
Answer:
The cell theory expresses that: all living things are made out of at least one cell; the cell is the essential unit of life; new cells emerge from existing cells.

- Anton van Leeuwenhoek, a Dutch researcher, utilized a magnifying lens to watch living lake living beings.
- Researchers found these cells in all creatures that they watched. it was also evident before forming cell theory that cell arises from cells.
