Explanation:
The data have high precision but poor accuracy because of a systematic error. Thus, the correct option is A.
<h3>
What is systematic error?</h3>
An error that is not caused by chance, but rather by a system-wide inaccuracy (in terms of observation or measurement).
The accuracy of a value refers to how close it is to its genuine value. An arrow's proximity to the bull's-eye center is an example. A measurement's precision refers to how repeatable it is. A systematic error has occurred.

Answer:
The closed circulatory system considerably enhances the speed, precision, and efficiency of the circulation. The blood flows far more rapidly and it takes less time to circulate through the closed system and return to the heart.
This situation listed in the question will not happen this way. The energy of cells works differently from the problem, as oxygen is fat-soluble and therefore requires no membrane protein to be transported across the cell membrane. In that case then, the supplement would not be able to increase the amount of oxygen in the cells.
