Please answer asap I'll give brainlist to the correct answer

This isn't as complicated as it looks.

1. If you have 10% solute, then you have 90% solvent because 90% + 10% = 100%..

2. If you have 20% solute, then you have 80% solvent because 80% + 20% = 100%.

3. The cell is hypotonic compared to the beaker because it has less solute inside of it. Usually people say the solution's tonicity and not the cell's tonicity though.

4. Because the cell has less solute than its environment, water will flow outside of the cell. Think of it as water flowing outside to "dilute" more concentrated areas. Water always flows from an area of low concentration to an area of high concentration to achieve equilibrium.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

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.
