Stuart designed and built a water filter in class. he wants to know if it will make water from lakes or streams safe to drink. which of the following would it be best for stuart to measure in an experiment in order to test his design and answer this question? a. the maximum force that can be applied to his filter without breaking it b. the amount of time required for different volumes of water to pass through his filter c. the diameter of the largest grain of dust, dirt, or sand that can pass through his filter d. the amount of bacteria and impurities in water both before and after it passes through his filter

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

allowed for the prediction of the properties of missing 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.
