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.

Answer: Directional selection
Explanation:
In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.
This causes the allele frequency to shift towards the time in the direction of that particular phenotype.
Here, in the question the acid tolerant plant species is favored over the other phenotype.
Hence, the correct answer is option D

Answer:
Production of ATP via oxidative phosphorylation require an intact mitochondrial membrane because of the creation of an electrical potential.
Explanation:
Oxidative phosphorylation is a method, in which energy is converted into ATP by a sequence of protein complexes located inside the mitochondrial inner membrane. Production of ATP through oxidative phosphorylation requires an intact mitochondrial membrane because a change in electrical charge between both sides of the inner mitochondrial membrane results in the creation of an electrical potential. The protons have accumulated on the exterior of the mitochondria, making it positive (H), while the protons have been lost within, making it negative. On each surface of the membrane, a differential or gradient in chemical concentration has been formed. The cell transmits the energy stored in the decreased NADH and FADH via the electrochemical gradient.
