The molecular clock is a scientific technique which presents a means of estimating evolutionary rates and timescales using genetic data. It uses mutation rate of biomolecules when two or more life forms diverged to estimate the time. Answer is B.
The fertilized egg begins a rapid descent to the uterus. The period of rest in the tube appears to be necessary for full development of the fertilized egg and for the uterus to prepare to receive theegg. ... At the end of this transition period, the embryo becomes a mass of very organized cells, called a blastocyst.
Answer:
The correct answer is option B. The contraction forces of the innervated muscle fibers.
Explanation:
Electromyography or EMG is the study of muscle activity with the help of analyzing electric signals that are burst or generated by the contraction of the muscle fibers. In other words, it is the electrical activity of the skeletal muscles in response to a nerve's stimulation of the muscle.
EMG uses the myoelectric signals to analyze muscle that is generated during the contraction forces of the inverted muscle fibers of the skeletal muscle.
Thus, the correct answer is option B. The contraction forces of the innervated muscle fibers.
<span>Mitosis is carried out for growth and development processes. The cell divide and multiply for growing and removing the worn out cells/damaged cells. Two identical daughter cells are formed in mitosis. Errors in the same may cause genetic disorders, Sex cells divide by the process of meiosis. </span>
In order to make the proton gradient, protons are pumped across the mitochondrial membrane at several points in the electron transport chain. However, that proton gradient is only used to make ATP by the ATP synthase, which is technically separate from the electron transport chain.
