Answer:
The sun (abiotic) affects the grass, trees, flowers, etc. by giving off its energy to the plants so they can grow.
Another example is water (abiotic) affects mostly every biotic factor such as humans, plants, or animals because all living things need water to survive.
The correct answer is option D, None of the choice.
Prokaryotes like Escherichia coli are used in drug production. Rhizobium bacteria (prokaryotes) in the soil, form symbiotic relationship with the roots of the plant to fix nitrogen. And prokaryotes are measured in terms of colony-forming units (CFU) of bacteria to produce nutritious yoghurt.
<em>Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm) </em>
<u>Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up. </u>
<em>The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC. </em>
As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.
Answer:
The correct answer will be option-A
Explanation:
The citric acid cycle is the cyclic chain of reactions taking place as a phase of the cellular respiration as it gets halted in the absence of oxygen.
The citric acid cycle converts the obtained acetyl-CoA to a usable form of energy in the form of ATP, NADH and FADH₂.
The citric acid cycle forms intermediates which are utilised by the organisms to synthesise the various biomolecules like amino acids, purines and pyrimidines.
The intermediates like alpha-ketoglutarate forms arginine, proline and glutamine whereas oxaloacetate forms asparagine and aspartate.
If bacteria do not receive the amino acids then they will synthesise the amino acids using intermediates of the citric acid cycle.
Thus, option-A is the correct answer.
