Answer:
I, II, III
Explanation:
A threshold stimulus is a stimulus that is capable to produce a response in excitable tissues such as neurons and muscle fibers. At threshold potential, the outward movement of K+ and inward movement of Na+ become equal to each other. When the potential exceeds the threshold potential, more and more Na+ enter the cell to depolarize it and to allow the opening of Na+ channels. Therefore, to fire an action potential, the threshold must be exceeded.
Conduction of action potential is all or none phenomenon which means that either it occurs or it does not occur. As an impulse is passed by each successive part of an exon, it enters the refractory period during which there is no conduction of nerve impulse. It ensures the one-way conduction of impulse from the cell body to the axon terminal only.
Answer:
Si.
Explicación:
Sí, un gas se puede condensar cuando su temperatura disminuye porque cuando la temperatura del área circundante del gas disminuye, se produce una condensación que cambia el estado de la materia i. mi. de gas a estado líquido. La principal razón de esta condensación es la aproximación de moléculas de gas que están muy alejadas unas de otras. Con una temperatura más baja, el volumen disminuye y las moléculas de gas se combinan para formar un líquido.
