Answer:
In photography the act of printing of developing a photograph is called photofinishing process.
In the aspect of DNA the process whereby the exact copies of genes sequences present in DNA is transferred and copied to the mRNA for subsequent synthesis of needed protein is called Transcription.This is a process of gene expression in the cells.Therefore if photofinishing involves the copying or reproduction of images, then the reproduction of gene sequences of DNA as RNA can be linked to transcription of DNA to RNA.

e. All of the above are correct.
Explanation:
Active transport is a type of transport in living systems in which molecules/ions/substances are moved or transported against their concentration gradient i.e. from a region where the substance is LOW to a region which it is HIGH, across a membrane. Since molecules are transported across a memembrane against their concentration gradient, an energy input in form of ATP is needed to do so.
Active transport is used in living systems to transport out secretory products and waste material against concentration gradients, take up nutrients from the environment against concentrations gradients etc. Since ions are substance moved by active transport from a low region to high region, there is an imbalance in the intracellular concentration of ions, such as Na, K etc.
Since there is no equilibrium in the concentration of ions on opposite sides of the membrane, an electric potential is formed across the membrane i.e. one part of the membrane will be more positively charged than the other.
A positive control is a group in an experiment that receives a treatment with a known result, and therefore should show a particular change during the experiment. It is used to control for unknown variables during the experiment and to give the scientist something to compare with the test group.
