The flow of <u>DNA → mRNA → protein </u>depicts the flow of information when a gene directs the synthesis of a cellular component.
Explanation:
Genetic information needs to flow in a specific pattern in order a gene to transform into a component like protein. This transformation takes place through the processes of transcription inside the nucleus and translation in the ribosomes. So the pathway: DNA → mRNA → protein will be correct flow of information for protein synthesis from DNA code. The mRNA or the messenger RNA encodes the genetic information or the chemical blueprint of the particular protein to be synthesized. This flow represents the central dogma of genetic information pathway or flow, which is; DNA encodes the RNA and the RNA encodes the Protein
Answer:
<u>The solution is isotonic.</u>
Explanation:
Saline solututions are mixtures of salt and water. In a normal saline solution, red blood cells maintain their shape. This is because the saline solution is isotonic. Essentially it has the same concentration as inside the red blood cell.
The water does not move down a particular gradient, thus the shape remains unchanged.
Answer;
Responsiveness
Excretion
Explanation;
Excess carbon dioxide must be removed from the body to stop it reaching toxic levels. As the blood flows through the lungs, excess carbon dioxide passes out of the blood and into the alveoli by diffusion. It is then removed from the lungs when we exhale (breathe out).
-Carbon dioxide helps remove carbon dioxide (a waste gas that can be toxic) from your body. The lungs' intake of oxygen and removal of carbon dioxide is called gas exchange. Gas exchange is part of breathing.

Answer:
It means Red Blood Cell or RBC is isotonic with 0.9% NaCl solution.
Explanation:
RBC or Red Blood Cell is an important blood cell that play an important role in the transport of Oxygen and Carbon di oxide to and from our body.
Red Blood Cells are isotonic with 0.9% NaCl solution which means if a red blood cell is kept in a solution containing 0.9% NaCl, it neither swells nor shrinks.That"s why RBC is isotonic with 0.9% NaCl solution.
This the only reason for using 0.9% NaCl solution as a saline.
