Key points
Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell.
Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.

Answer:
Natural selection can be described as a phenomenon in which individuals of a population which are better adapted to survive in an environment are favored by nature as compared to the individuals of the population which lack better characteristics to survive in the environment.
Through natural selection, evolution occurs and the allelic frequency changes over a period of time. The process of evolution as well as change in the allelic frequencies does not occur just by a single individual, rather it is a collective effort which takes a lot of time. Hence, we say that natural selection changes the population and not a single individual.

The sensory cells present on our retina that are responsible for our vision are known as rod cells and cone cells. Rod cells do not allow us to see in color, only black and white, and are better in low-light conditions. Cone cells are responsible for our ability to see colors but are bad in low-light conditions. Cone cells are able to sense red, green and blue colors. When one type of the cells will be stimulated, the remaining will show an "afterimage" due to the overstimulation of the complementary cells.
