The scientific study of life, called Biology, can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has  emergent properties that result from interactions among component parts. Life's basic unit of structure and function is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, nutrients and chemicals cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of evolution all of life is related by common descent. Life was diversified as natural selection had led to the gradual accumulation of adaptations that fit populations to the environment.

Explanation:

Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.

Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.

Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.

The potential must be strong enough to send a(n) potential to the CNS.

salantis [7]

It is true that the potential must be strong enough to send a potential to the CNS. The stronger the potential, the more it will excite the transmitter in relaying the message to another neuron, therefore, if this happens, the more will it be easier to pass the message.
