Explanation:

Prenatal diagnosis manipulates a diversity of procedures to discover the fitness and state of an embryonic fetus.  The usual primary system to accomplish is just to study at the embryo or fetal parts. The analysis of an entire embryo is most helpful, though information can furthermore be obtained from an investigation of fetal components.

Most utmost ladies accept prenatal genetic testing to understand what the uncertainty is ere the infant is turned. They would willingly acknowledge the information while pregnancy than at birth so they can compose ideas and choices onward of the period.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
