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.
Because it has the ability to get light, photosynthesis would happen. Since it is in an airtight jar, it will use all the CO2 in the jar until all the CO2 is gone and there is only Oxygen left. Photosynthesis's rate will decrease rapidly. After that, the plant will have no more energy since there is no CO2 to allow it to keep with photosynthesis, so it would die off.
For a punnett squares the F is the dominant gene and the f is the recessive gene
So the top would most likely be a male and the top would a male and the side would be the female
