The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.
The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.
The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.

Cancer is an abnormal and uncontrolled multiplication of cells.
<span>Cancer also involves abnormal cell growth with the potential to spread to other parts of the body via blood and to form metastasis. Cancer cells avoid apoptosis (programmed cell death), have the limitless number of cell divisions and promote blood vessel construction. There are more than 100 types of cancers that affect humans with different signs and symptoms and with many different causes. </span>
This is not a biology question this is a math question
