In a science experiment, you studied how the amount of sunlight affects the height of 5 sunflower plants. you recorded your observations in the data table below.

what is the dependent variable in this experiment?
question 4 options:

soil type

hours of sunlight

amount of water

total growth of the plants

Total growth of plants

Explanation:

In an experiment the dependent variable is what you are testing. In this case you are testing if height is affected by the amount of sunlight. It is called dependent because the result would be dependent on the controlled or independent variable.

The independent variable on the other hand, is the variable that is controlled, or manipulated to see changes on what is being tested (dependent variable).

what's the

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.
