Answer:
Crossing over is a biological occurrence that happens during meiosis when the paired homologs, or chromosomes of the same type, are lined up. Hope this helps :)
Explanation:
The type of microscope of advanced technology that can produce 3D mages of a cell’s surface is an electron microscope. This microscope uses electron signals to project the surfaces of the cells. The difference between a <span>prokaryotic cell and a eukaryotic cell is the presence of the nucleus. The nucleus is the center of all processes of the cell</span>
The earth is about 6,000 years old.
Answer - Yes! of course. For better outlook you want to be in a city like Miami, FL U.S or someone populated cause that is where your able to find patients in need of recover.

Reasoning - It is in fact true because in a city you can find a populated are that probably fractured their hand and needs some assistant for help recovery if the main doctor is not there.
In a resting state, sodium (Na ) is at a higher concentration outside the cell, and potassium (K ) is more concentrated inside the cell. During an action potential, the sodium levels <u>increase </u>inside the cell.
During an action potential, the potassium level inside the cell decreases, and the sodium level inside the cell increases. That is to say, there is an outflow of potassium and an inflow of sodium ions.
Action potential usually occurs when an electrical signal disrupts the balance of Na+ and K+ within a cell membrane, briefly depolarizing the concentrations of each.
