Answer:
The answer to this definition is: ACTION POTENTIAL
Explanation:
Action potential is a phenomenon in nervous system used to describe a change in electrical current that occurs when an impulse passes through a neuron or nerve cell. Action potential is induced when sodium (Na+) ions move from the extracellular environment into the intracellular environment.
Impulse travels across the axon of a neuron and thereby causes a difference in the electric potential i.e. - mv to + mv. This process, according to this question, whereby a change in electrical potential occurs due to the passage of an impulse through a nerve cell is termed ACTION POTENTIAL.

crustal rocks ______________
Answer:
Option (2).
Explanation:
Inflammation may be defined as the natural process that helps the body to defend and helps in healing of the body. The production of white blood cells increases at the time of inflammation.
Leukotrienes, histamine, bradykinin and prostaglandins are the chemicals that mediate inflammation process. These chemicals increases the production of immune cells and causes redness, heat and swelling in the body.
Thus, the correct answer is option (2).
Answer:
desarrollo de tumores y en última instancia metástasis
Explanation:
El cáncer es una enfermedad que está caracterizada por la facultad de las células de sortear mecanismo de muerte celular programada (apotosis). Las células cancerosas poseen mutaciones que les permiten evadir estos mecanismos de regulación celular, los cuales garantizan el normal funcionamiento celular y en última instancia una correcta división celular. En ocasiones, las células cancerosas se desprenden del tumor original y migran hacia otros tejidos donde se multiplican indescriminadamente, este fenómeno se conoce como metástasis.
