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.
The answer is C where the star is found in the sky. If a star is moving toward us, its spectroscopy will be observed at shorter wavelengths, this is called "blueshifted". If the star is moving away from us, the lines will appear in longer wavelengths, and that's called "redshifted".
Sorry for a late response, but I hope this helped.
Answer:
A. Fertilization
Explanation:
The development of a human being begins with fertilization, a process by which two highly specialized cells, the spermatozoon from the male and the oocyte from the female, unite to give rise to a new organism, the zygote.
1. Moist air
2. The less dense air, the less oxygen (at least that's what my teacher says)
