What else can I help you with?
The distance between Z-discs during muscle contraction?
Decreases
What is the difference between contraction and expansion?
Contraction refers to a decrease in size or volume, while expansion refers to an increase in size or volume. In the context of economics, contraction can refer to a decrease in economic activity like during a recession, while expansion refers to a period of economic growth.
Which of these would cause the gravitational force between earth and the sun to decrease?
An increase in the distance between Earth and the Sun would cause the gravitational force between them to decrease. Conversely, a decrease in the mass of either the Earth or the Sun would also result in a decrease in the gravitational force between them.
When the left ventricle contracts does the distance from the apex to the base increase or decrease?
When the left ventricle contracts, the distance from the apex to the base decreases. This contraction, known as systole, causes the ventricular walls to shorten and thicken, effectively reducing the overall length of the heart chamber. As a result, the apex moves closer to the base during this phase of the cardiac cycle.
What happens to the distance between the spinous processes during flexion of the spine?
During flexion, the distance between the spinous processes is increased.
Do the you band and H zones become narrower during contraction?
Yes the H band shortens. During contraction the length of the sarcomere or from z line to z line must decrease in length. Thus the I band which is bisected by the z line must shorten as well as the H band, even though the H band is bisected by the A band it must shorten to allow fior this decrease in length. The A band does not shorten because it is composed of the entire length of myosin whose length never decreases during contraction.
Which will decrease in an ordinary well during a dry season?
distance from the ground surface to the water level in the well
What is thedifference between displacement and distance?
Distance travelled is the total distance covered during the motion and displacement is the distance between the final and initial position.
What muscle contraction occurs in the biceps brachii during the upward phase of the bicep curl?
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!
Does the Z line shorten during muscle contraction?
Yes, the Z line shortens during muscle contraction.
What happens to a muscle contraction if there is an excess amount of either Ca2 plus or ATP present during the contraction?
During muscle contraction the actin heads pull the sarcomere closed
During which phase change does the average distance between molecules always increase?
During the phase change from a liquid to a gas, the average distance between molecules always increases.
