An experiment was conducted to determine if hot water will freeze faster than water at room temperature. Which of the following is the dependent variable? 1.Temperature of the freezer 2.The water at room temperature 3.The hot water 3.The rate of freezing

The dependent variable is the variable that changes when the independnet variable is manipulated.

Explanation:

The independent variable is the water temperatures, the variable you change. The dependent variable is the rate of the water freezing.

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.
