1. As an environment that maintains pH at a certain level. 2. As an independent variable. 3. As a solution to dissolve test compounds. 4. As a means to provide nutrients to biological tissue.
Item number 2 is the correct answer. A buffer helps in neutralization for a solution to have balanced pH levels and to keep its stabilization. It can be added or lessen in an acid-base solution to maintain its pH at a steady level. Thus it is less likely to be an independent variable in chemistry tests as it helps in having a constant level of a solution.
If a buffer is not used in a solution, it can lead to an explosion or not getting the desired results. Buffers also provide nutrition to the blood and muscle cells. It aids the body to resist fatigue and improve energy levels to complete high-intensity exercises.
As an independent variable.-a physiological buffer can perform many useful functions, but it should not be used as an independent variable. depending on which salts are used, a buffer can be used to keep ph at a fairly steady level during an experiment. it can be very useful for biological processes that occur at specific ph levels, and can be useful for keeping test agent ph at a certain level as well. glucose from other energy sources can be added to the buffer to promote cellular respiration. unless one is specifically testing the role of a buffer in a biological process, it should not be the independent variable. of the choices listed, using a buffer as an independent variable is its least likely used.
