Why did comets form in the kuiper belt and not in the asteroid belt

Asteroids lie in the asteroid belt and comets lie in the Kuiper belt beyond the orbit of Neptune. The composition of asteroids and comets is different.

Comets are composed of rocks, dust, ice and frozen gases. These are thought  to be formed from the debris of the solar system.

On the other hand, asteroids are irregular shape and size rocky bodies lying between the orbit of Mars and Jupiter. There are thought be remnants of a planet which could not form.

Comets formed in the Kuiper belt because of very low temperature and what they are composed of.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
