The life-form during the Precambrian time was cyanobacteria.
Well, the COD determines/indicates the amount of oxygen which is needed for oxidation of all organic substances in water in mg/l or g/m^3.
Answer: The corn plants were damaged by the herbicide.
Explanation
Depending upon the plant affected and the herbicide used, effects of herbicide damage differ. Popular signs include flattened stems or twisting or corkscrewing. Leaves can have shapes, sizes or textures that are irregular. Moreover, yellow or reddened leaves or leaf veins may. This usually leads to loss in crops as noticed from the maize plantation where more than half was lost.
Explanation:
According to the chemiosmotic hypothesis, ATP is produced by due to the proton gradient created across the mitochondrial membrane. The essential components required for chemiosmosis are proton pump, proton gradient and ATP synthase. ATP synthase is an enzyme which helps in ATP synthesis. The enzyme ATP synthase has two part
F0 andF1.F0 is the part which transports protons across the membrane as a transmembrane channel while configuration changes in F1
activates the enzyme. They phosphorylate ADP i.e., add one more phosphorus group to the ADP and converts ADP(adenosine diphosphate) to ATP (adenosine triphosphate). The proton gradient developed across the membrane is the driving force of ATP synthase.
