Genetically-engineered bacteria are sprinkled on the oil to digest it.
Explanation:
Genetically engineered or modified microorganisms (GEM or GMO) like bacteria are engaged to digest oil spills through the process called bioremediation.
The enzymatic action of these specialized bacteria to degrade or decompose and remove harmful environmental contaminants. When a leakage occurs in a oil tanker, all the gallons of oil stored in it are leaded into the ocean which poses a very huge danger for the marine environment and to all the biotic factors including humans who are dependent on the marine environment.
Removing the oil spill from the ocean waters is very tough and utilizing such novel technology will be very useful. Bacteria like Alcanivorax, Methylocella are commonly engaged to remove oil spills. These bacteria acts by breaking the hydrocarbon bonds of the oil and will digest and clean the oil spill.
Answer:
The correct answer would be They comprise the Calvin cycle.
Calvin cycle refers to the set of chemical reactions taking place in the stroma of the chloroplast in which carbon is fixed into food (glucose). The whole process is divided into three stages namely: fixation, reduction, and regeneration (ribulose bisphosphate or RuBP).
It takes place in light-independent reaction of the the photosynthesis.
It does not require light energy to carry out the reactions however, it depends upon the products of light reaction (ATP and NADPH).
Fixation of one molecule of glucose requires 6 molecules of carbon dioxide, 9 ATP and 6 NADPH.
The fixation of carbon is catalyzed by an enzyme RuBisCO.
Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.
