stira [4]
A decreased pH coupled with a decreased plasma concentration of bicarbonate ion indicates that acidosis is occurring and the respiratory system will compensate for this change.  
<span>Acidosis (metabolic) is a state when increased acidity in the blood occurs and it usually refers when arterial pH falls below 7.35. Metabolic acidosis may result from increased production of metabolic acids (lactic, for example) and is characterized by low pH, low blood HCO3, and normal or low PaCO2.

Andru [333]

Answer:

The correct answer is -

Independent variable - change in the concentration of carbon dioxide

Dependent variable - bubbles produced

The independent variable of an experiment or study is a variable that is subject to change or being manipulated during the study to find the response on the dependent variable. The concentration of carbon dioxide is here manipulated to find the change in the amount of bubble produced.

The dependent variable is a response that is carried out by the change or manipulation of the independent factor. In this case amount of bubbles is the dependent variable.

Thus, the correct answer is -

Independent variable - change in the concentration of carbon dioxide

Dependent variable - bubbles produced
