Answer:
The correct answer is - when action potentials trigger the release of neurotransmitters.
Explanation:
Communication between neurons takes place by signaling that can be either chemical signaling or electrical signals. Communication between neurons occurs at very small gaps known as synapses.
These synapses have two specialized cells that help two neurons communicate by one to another to allow for chemical transmission. The chemical that isreleased due to the stimulation of the action potential in order to communicate the neurons are known as neurotransmitters that allow for transmission.
Answer:
Option A, Competition has restricted the ranges of both species
Explanation:
When two species which depend on the exactly same kind of resources, get into a mode where they prefer to stay in two different ecosystems without interfering each other’s circle and thus they get excluded from each other due to competition. This phenomenon of the ecosystem is called Competitive exclusion
According to Gause's Law of competitive exclusion two species which are competing for similar kind of resources are unable to stay together.
Hence, option A is the correct choice.
