With the application of a stimulus voltage, the isolated muscle fibre will show contraction fully after the threshold voltage is achieved. An increase in the stimulus voltage will increase the force of contraction, but the amount of contraction will remain the same.
Explanation: Muscle fibres do contain the contractie proteins like actin and myosin. With the advent of an electrical stimulus, there's a change in the intercalated discs or the T junctions of the muscle fibre which leads to the opening of calcium channels of sarcoplasmic rericulum. This increases the calcium ion concentration of the cell and the actin heads get opened which leads to the sliding movement of actin over myosin and thereby contraction occurs.
According to the All or None principle, the muscle fibre will show contraction fully, or won't show any contraction. Sl here, with increase in stimulus voltage, the contraction will be more powerful, but the extent of contraction will be same for all voltages above threshold.
Answer:
1. Integrity
2. Health Care
3. Code of Ethics
Explanation:
I calculated it logically
The correct answer is “kerat/o”
Combining form is when it has the “o” on it
Mowrer's two-factor theory gives us a valuable starting point for dealing with many of those manifestations in which fear limits well-being.
<h3>How would the two process theory explain the early development of a phobia and how would it explain how the phobia could continue for a long time?</h3>
The Doctor Orval Hobart Mowrer focused his research on behaviorism. He established that the first process that involves the emergence of phobias and many anxiety disorders is classical conditioning:
A seemingly neutral and innocuous stimulus (an airplane, a spider, a work scene, a crowded supermarket, etc.) suddenly becomes a painful or traumatic stimulus.
With this information, we can conclude that after suffering the impact of classical conditioning (a specific stimulus acquires a painful connotation), it would be enough to avoid this situation to return to normality. However, when it comes to phobias and anxiety, the brain works differently.
