Answer:
1. Signaling molecule
2. Signaling receptors
Explanation:
Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.
For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.
Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.

Answer:
Azimuthal map projections
Explanation:
The Azimuthal map projections come in a circular shape. They represent the whole world but in a different manner than that of the other map projections. The other map projections tend to have problems with the size of the objects as they get further away from the Equator, but this map projection doesn't have that problem. The Azimuthal map projections actually represent all of the places on Earth with their correct distances from the central point, and they all have their sizes correct proportionally to the scale, thus making an accurate map projection.
