What happens to density during thermal contraction?
It increases. The volume of a material decreases in contraction, while the mass remains the same.
What happens to the h zone during contraction?
width of H zone decreases
What happens to the strength of contraction during wave summation?
It increases about to about four times greater than a normal contraction for skeletal muscle.
What is measured by the amount of time a muscle group can sustain a contraction?
Muscle strength measures the amount of force a muscle can exert during contraction. The determining factor of strength is the fast twitching fibers.
What happens to z line disc during contraction?
it comes closer and m line becomes dense
What happens to particles during chromatography?
Particles present in the dye to be separated is dissolved by the solvent and then carried throught the chromatographic paper, the extent to which each die will travel will depent on the amount of that die is present in the sample die.
What happens If a muscle is applied to a load that exceeds the muscle's maximum tension?
The muscle length will not change during a contraction.
Which region of a sarcomere shortens during contraction?
During a contraction, the I bands and H zone of a sarcomere contract. The A bands remain unchanged.
During the process of euthrophication what happens to the oxygen present in a lake?
Decreases
What happens to a Z line during contraction?
the Z line discs come closer together and the & the width of the I band decreases.. or narrows
What describes the events of contraction in excitation-contraction coupling?
cross bridge formation "Excitation-contraction coupling" connects muscle fiber excitation to the muscle fiber contraction (cross bridge formation). During contraction, myosin heads form cross bridges many times-with each cross bridge generating a small amount of tension in the muscle fiber.
What happens during combustion of hydrogen?
combustion which result to a colourless smoky flame (depending on the amount of carbon present) giving off carbon dioxide and water
