The electron transport chain is part of the overall processes of cellular respiration and photosynthesis. The solution is A.
The correct answer is iron.
The scientists from Britain discovered a soap with magnetic characteristics that could exhibit huge applications in the manner to fight against the damaging oil spills. In the mentioned soaps, the iron-abundant salts are supplemented to establish metallic centers inside the particles of the soap.
After the solution is treated in a water source, a magnet was utilized to subjugate both the surface tension and gravity of the water, levitating the iron-rich scrubbing bubbles so that they can be withdrawn easily.
