What are four conditions required for fossilization of an organism? Write each condition in the left

Four conditions for fossilization:

Only dead organism or plant

The dead to be buried quickly

Prevention of decaying and decomposition of the dead

Dead to be buried in environment where carbonates precipitate at large

Explanation:

The plants or animals preserved in sedimentation rock are said to fossilized and the process is called fossilization.

Conditions for fossilization are:

1) Only dead organism or plant: Only dead animal or organism are considered for fossilization.

2) The dead to be buried quickly: To preserve the organism a death by natural calamity is best.

3) Prevention of decaying and decomposition of the dead: The animal needs to be kept in anaerobic conditions and ensured that bacteria do not throng and start the decaying process.

4) Dead to be buried in environment where carbonates precipitate at large:

The soil should be rich in mineral rich water in which carbonates are in excess. The carbonates will get deposited on the degrading tissues and the tissue attain the shape of rock formed by carbonates.

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.
