Answer:
A) increasing frequency of action potentials only.
Explanation:
If the muscle fibers begin the contraction with the sarcomere too elongated, the thick and thin filaments would be barely overlapping, forming few crossed bridges. On the contrary, if the sarcomere is too shortened so that the thick filaments reach the z-disks, the myosin is unable to find new fixation sites for cross-bridge formation and the tension decreases rapidly.
But to better understand how the contraction force increases, it should be noted that a single contraction does not represent the maximum force that a muscle fiber can develop. <u>The force generated by the contraction of a muscle fiber is increased, increasing the frequency with which the action potentials of the muscle stimulate said fiber,</u> that is to say that the nervous system controls part of this.
A potential muscular type action lasts between 1 and 3 ms. While muscle contraction can last 100 ms. If the repeated action potentials are separated by prolonged intervals of time, the muscle fiber has time to fully relax between the stimuli. If the action potentials continue to stimulate muscle fiber repeatedly at short intervals (high frequency), the relaxation between contractions decreases until the muscle fiber achieves a state of maximum contraction known as tetanus.
The word hurricane originated from the name of the Mayan god hurcan
Answer:
Kinetic energy
Explanation:
Kinetic energy is motion; it is the motion of waves, electrons, atoms, molecules, substances, and objects. Electrical energy is the movement of electrons. Everything is made of tiny particles called atoms.
People are well connected to living things and others , such as trees and plants because humans take in oxygen that plants produce , and when animals or worms die the decompose into the ground which makes the ground and soil rich.
Explanation:
It all depends on ur way of living.
