The H-zone in a contracted sarcomere differ from that of a relaxed sarcomere because H-Zone is narrower in contracted sarcomere. In a striated muscle sarcomere is small unit of myofibril. Between two Z line sarcomere is the repeated unit . Sarcomere is the very basic unit that makes up our skeletal muscle.
Answer:
Option (1).
Explanation:
Action potential may be defined as the change in the cell potential that helps in the transmission of the nerve impulse. The resting membrane potential of the cell is -70mV.
The depolarization phase of the cell has membrane potential towards more positive. After the depolarization phase, the sodium channels are closed and potassium influx occurs that causes the re-polarization of the cell. This activity of the re-polarization is not the consequence of the closing of the inactivation gates.
Thus, the correct answer is option (1).
Answer:

C: 280
Explanation:
An explanation of this question is what is the total surface of the pyramid,
what I did was multiply 14 x 20. How did I get the 20, I got it because since the two sides on the bottom are equal, add the 10+10 and you have 20. So the equation should be 14 x 20.
(If this doesn't help I'm sorry).
