Answer: KIDNEY (URINARY/EXCRETORY SYSTEM) helps regulate water and electrolyte balance.
Kidney is an important organ of our urinary system that regulates chemical composition of blood, regulates water and electrolyte balance, etc in our body. Kidney is made up of nephron cells that filters water, reabsorbs amino acids, secrete and excrete urine outside the body.

Explanation:
Experimentally, when trying to determine the concentration of an unknown sample of CuSO₄ with known absorbance, a standard curve is used. The standard curve is a scattered plot/graph in which known concentrations and there respective/corresponding absorbance are plotted on a "X and Y axis" graph (scattered plot). The absorbance is represented on the y-axis while the concentration is represented on the x-axis.
Once this known values are plotted on the standard curve, an unknown value (either absorbance or concentration) can be extrapolated from the curve. What is missing from the question is data required for the standard curve.
This question shows the absorbance of the CuSO₄ has been determined (most likely using spectrophotometer), the concentration could have been extrapolated from a standard curve.
An example of a standard curve is provided in the attachment for guidance.
