An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. The biological synthesis of chemical compounds in the presence of light
The right answer is C
This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).
Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.
Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).
NO3- ==> NO2- ==> N2.
Answer:
Negatively repressible.
Explanation:
A control which occurs through repressor is known as negative control which may be inducible or repressible.
When a small molecule named as allolactose binds this repressor it leads to allosteric repulsion which removes repressor from the operator as a result of which RNA polymerase can start transcription. Allolactose is therefore known as inducer because it induces lac operon expression.
But here, the operator is active (induced) already so there is no need to induce the operon which means that it can only be repressed so that transcription could stop. So the answer is negatively repressible operon.

Answer:
1) By breaking of ATP to ADP
2) The sodium and potassium ions are transported using active transport process!
Explanation:
In cell, the movement of ions across the membrane at the expense of energy is known as Active Transport. The energy is used in the form of ATP(Adenosine Triphosphate) that gets converted to ADP(Adenosine diphosphate) during transport. It takes the ions from high concentration to low concentration. ADP contains one less phosphate group that ATP, as their name indicates and plays a prime role in the flow of energy to the cells.
