Boron has 5 protons. if another proton gets added to boron, what will happen?
a. nothing, it will still be boron.
b. the amount of neutrons will change as well to make up for the addition of protons.
c. it will be a different element because the identity of an element is determined by its protons.
d. it will start to decay because it has become unstable.

"C"

Explanation: Protons have a positive charge in an atom. Since elements in the periodic table are arranged left to right, and top to bottom, in order of increasing atomic number, if you change the protons this will change the element. If there are 5 protons if boron, if we add another proton this will change our element to Carbon. Therefore, if another proton was added to boron it would change elements.

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.
