Answer:
Dissociation of the myosin head from the actin filament requires the binding of ATP (I).
Many trials are taken and averaged in an experiment to reduce the measurement error.
A great manner by which error is reduced or to enhance the accuracy of measurement is to take many measurements and compute their average. In other terms, one attain accuracy via averaging.
This also validates the repeatability of the measurement. The kinds of experimental error include mistakes in data entry, human error, mistakes in the design of the experiment, or systematic error, or random error due to environmental circumstances.
The answer is A because it is the best answer that the students gave.
Answer:Muscles relax and contract when one muscle pulls and moves your body part and if you want to do the opposite movement the opposite muscle contracts, allowing the first muscle to relax.
