Answer:
True
Explanation:
With the increase in altitude, the atmospheric pressure and amount of oxygen decreases.
When a person moves to high altitude, they adapt to the lack of oxygen by increasing their red blood count and the process is called acclimatization. The lack of oxygen is monitored by the peripheral chemoreceptors, that increases ventilation. The body starts producing red blood cells (RBC) in order to resist the lower oxygen saturation in blood in high altitudes.
That is why, people living in high altitudes have higher red blood cells count in comparison to people living in cities or plain areas.
Hence, the given statement is true.
<span>Mitosis is a part of the cell cycle in which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, and each set ends up in its own nucleus.
It is important that the cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.
