B, it doesn’t move, I learned it when I was in school
Answer:
Explanation
The Axon or nerve fibre is a long, thin projection of the neuron or nerve cells that sends signals in the form of electrical impulses from the cell body (soma) to the synaptic terminals. The axons are of two types: myelinated and unmyelinated. The unmyelinated axons lack myelin sheaths which make the transmission of electrical impulses slower while the myelinated axons transmit electrical impulses faster.

Is Complex III reduced or oxidized?
Process - During each two-cycle process, the modified Q cycle in Complex III reduces cytochrome c, oxidizes ubiquinol to ubiquinone, and transfers four protons into the intermembrane gap.
Does ubiquinone get oxidized or reduced?
- At the cellular level, CoQ10 exists as a redox pair, or in two forms that alternate back .
- Forth as CoQ10 transfers a hydrogen in the mitochondria's electron transfer chain: ubiquinone, which is the oxidized form, and ubiquinol, which is the reduced form.
What is the function of complex III?
- The mitochondria of cells, which transform the energy from food into a form that cells can utilise, are where Complex III is found.
- Cells obtain a great deal of their energy from a process called oxidative phosphorylation, which is carried out by a number of complexes, including Complex III.

<u>The complete question is -</u>
We now get to the crux of the matter. If we are to identify which step is blocked, we will need at least two specific pieces of information.
Now let's put it all together . If you were told that ubiquinone was reduced but cytochrome c was oxidized , you would know that the pathway was blocked somewhere between these two carriers , but you would not necessarily know whether the block was at the ubiquinone ⇒ Complex lll step or the Complex III ⇒ cytochrome c step.
To differentiate between these two steps, you add an unknown inhibitor to a suspension of rapidly respiring mitochondria. After subjecting the suspension to MAGIC analysis, you find that there is an accumulation of reduced ubiquinone and that Complex III is oxidized.
Answer:
option A
Explanation:
In Recombinant DNA technology which involves DNA molecules formed by recombination to bring together genetic material from different sources, producing sequences that would normally not be found in the genome. Some basic steps are to be followed in the formation of your recombinant DNA. The restriction enzyme used in cutting the gene of interest from the pine tree DNA should also be the same used in cutting open the plasmid to make complementary sticky ends. Then integration of the isolated gene of interest into the cut plasmid and then this is treated with ligase to join the cut sticky ends. This construct is then introduced into bacterial cells.
Answer:
Pot Q would contain more concentration of nitrogenous compounds than Pot P.
Explanation:
Plants require certain inorganic nutrients for their growth and development. One of these nutrients is Nitrogen. Nitrogen is an integral part of certain biomolecules and structures in organisms including plants e.g nucleic acids (DNA and RNA), Chloroplast in plant cells, Amino acids etc.
Plants, through their roots, absorb nitrogen in form of nitrogenous compounds like ammonium, nitrates etc. present in the soil. Certain bacteria in the soil help fix nitrogen into usable compounds by the plants, since plants cannot absorb nitrogen directly from the atmosphere.
In this case, Moin measured the concentration of nitrogenous compounds in a particular soil prior to planting. He then separated the soil into Pot P and Q. He planted sunflower seeds in Pot P and planted nothing in Pot Q. If he measures the concentration of nitrogenous compounds in both soil, he should observe that the concentration of nitrogenous compounds in Pot P has reduced due to absorption by the roots of plants grown in them. The concentration of nitrogenous compounds in Pot Q would now be more as there are no plans to absorb them.
