Phosphate buffer is a buffer used in many types of reactions with the function to maintain constant pH value.
This is important because enzymes’ activity is affected by changes in pH. There is an optimum pH for every enzyme that can be defined as most favorable pH value or the point where the enzyme is most active. Phosphate buffer is often use in the measurement of enzyme’s activity because it is isotonic and non-toxic to most cells.
If the dogs are different breeds, their activity levels could be different because of their breed and not the caffeine. The correct option is A.
<h3>Reliability of experiments</h3>
In order for the outcomes of scientific experiments to be reliable, constant variables should be kept constant.
In the illustrated experiments, the breed and age of the experimental dogs have to be the same. It is one of the variables that have to be kept constant throughout the experiment.
If the dogs are different breeds, their activity levels could be different because of their breed and not the caffeine. The same thing is applicable to different ages.
Thus, evaluating this variable and doing right by it will ensure reliability.
