Answer: Receptor
Explanation: a protein that detects a signal molecule and performs an action in response.
A receptor protein is a type of protein that detects a signal molecule (ligand) and performs an action in response. It can induce a chemical reaction within the cell or initiate a signaling pathway which can change the cell's behaviour.
A protein that detects a signal molecule and performs an action in response is called a receptor protein. Receptor proteins in or on a target cell bind to specific molecules outside the cell called ligands. When a ligand binds to its specific receptor, it induces a chemical reaction within the cell. This binding could open a channel for certain ions to flow into the cell or initiate a signaling cascade or pathway with the help of second messengers, enzymes, and other proteins. The signaling cascade eventually leads to a change in the cell's environment or behavior. For example, neurotransmitters such as dopamine can act as ligands, binding to dopamine receptor proteins on nerve cells and causing specific responses in these cells.

Explanation:
I just did the quiz and I got the correct answer.
You will need an empty bottle (with a medium or small opening) made of clear glass, some hot water, and an ice cube.
Place some hot water in the bottom of the bottle and put the ice cube over the opening of the bottle so that it rests on top and drips into the bottle.
it really does depend on what type of 'cell' your talking about. If your talking about a battery type of cells then it's obviouse but I know that there are 3 trillion cells in your body :) reply if this was helpfull
Answer:
dominant alleles can take over the recessive alleles if they were there
and the other allele cant do the same as long as the dominant alleles don't
