The fertilized egg begins a rapid descent to the uterus.

At the end of this transition period, the embryo becomes a mass of very organized cells, called a blastocyst.
I think what they rely on is there experiment and how they do it
No muscle contraction will be observed.
<h3>What is the effect of calcium concentration on muscle contraction?</h3>
The concentration of calcium ions in the muscle cells help in contraction and relaxation of muscles fibers.
Release of calcium ions initiate muscle contraction.
Therefore, there will be no contraction of muscle if calcium ions are not transported out from the sarcoplasm.
