Answer:
B) action potential
Explanation:
The ions continuously flow across the cell membrane in the cells which establishes a membrane potential across the membrane. The cell membrane tries to maintain the negative potential between -40 to -90 mV.
At rest the neuron cell maintains the membrane potential around -70mV and this potential are known as the resting potential.
When the positive ions especially sodium ions enter the neuron then the positive charges get accumulated inside the cell. This changes the potential to a more positive value and when it crosses the threshold of -55mV then an action potential is formed.
In the given question, if the membrane potential changes from –70 to +50mV then an action potential will be generated in the neuron cell.
Thus, B) action potential is the correct answer.
Answer:
During the Mexican National Era of Texas history, there was support among many Anglo-American settlers for
Texas to be made into an independent state of Mexico.
Explanation:
Initially, Texas was known as Spanish Texas. Between 1821 and 1836 it became known as Mexican Texas after the independence of Mexico from Spain. It even attained a Republican status, independent of Mexico in 1836 after Mexico's independence war drove away Spain in 1821. After nine years of being a republic, it agreed to join the United States of America. During its independence, Texas tried to expand its territory into South and West of Mexico.
