We couldn't be where we are without microscopes and other technology. We couldn't study almost anything we know without these modern inventions.
The answer is: They will not continue with pregnancy, if baby is born they rarely survive beyond early childhood.
Most of the zygote with serious chromosomal problem will be dead before labor. A big genetic problem will cause the baby unable to survive. Most of the abortion at the first trimester pregnancy is happen because of the chromosomal problem. If the baby survive till labor they will still have some health problems and most will not survive long.
All of them will lead to depolarisation.
<h3><u>Explanation</u>:</h3>
Depolarisation is a phenomenon ebochor occurs in the excitable tissues of our bodies, namely the neurons and the muscle T junctions. Here the membrane is already polarised by means of difference in charges as well as concentration of ions on both sides of the cell membrane. With a single stimuli, this change in concentration is gone, and this is de polarisation.
This phenomenon occurs because of the opening of the ion channels like potassium channels and sodium channels which leads to a diffusion of ions from both sides to the other achieving a more or less equal concentration on both sides of cell membrane.
Now this opening of the ion channels can be triggered by means of different stimuli. In case of neurons, the opening of the post synaptic ion channels are guided by the chemical impulse taking in synapse.
In case of inter neuron transfer, the ion channels open due to change in voltage of the previous part of the axon.
In case of organ of Corti, the sodium channels open due to mechanical events occurring inside cochlea. So ion channels can open in any form will lead to change in potential.
