Answer:
When a neuron fires and its electric charge travels down the axon, causing neurotransmitters to be released by the neuron's terminal buttons, an <u>action potential</u> occurs.
Explanation:
An action potential, commonly termed as impulse, can be described as messages which are transferred in electrical form. Action potential are caused due to different electric charges. An action potential is generated by a stimulus which causes transfer of sodium ions into the axons resulting in depolarization of the neuron. To overcome this, potassium ion will enter the cell and an action potential will be generated.
The action potential causes release of the neurotransmitters so that signal messages could be transferred.
Biogeography is the study of geographical distribution of fossils, various species (plants and animals) and ecosystems throughout geological time and space
B. Hold large amounts of food.
Some parts of plant materials, like cellulose, are hard to digest. The digestive tract of herbivores is adapted so that the food can be digested properly.
