Answer:
This question is incomplete
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.
In the twilight zone, the temperature and the light conditions change. The initial 200 meters of the ocean as considered as the open ocean. There is availability of light and thriving temperature there. Butt below that, in the 'deep ocean'. The availability of light decreases and as we go further down, the light no longer reaches those parts of the ocean. Moreover, the temperatures plummet down to almost freezing conditions. In addition to this, the pressure is much more higher in the deep ocean.
