Name the process of identifying genetic defects by examining a small sample of fetal cells drawn by a needle inserted into the amniotic fluid surrounding the unborn fetus.

Amniocentesis or Amniotic Fluid Test or Amnio is the process to examine genetic defects, fluid infection or sex determination by inserting a needle into the Amniotic fluid surrounding the unborn fetus.

Explanation:

Amniocentesis

Amniocentesis is a prenatal diagnosis which is used to determine genetic defects, fluid infection or sex determination by inserting a needle to draw a small sample of fetal cells through the amniotic fluid surrounding the unborn fetus.

The prime aim of Amniocentesis is to detect chromosomal deficiencies and cure the fetus with all possible processes so that the baby may be normal and healthy at the time of delivery.

This process is performed when the woman is 15-20 weeks pregnant. The test has the tendency to spread quick and possesses the probabilities of miscarriage.

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.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
