Answer:
23 pairs nucleus parents and dna
i know that the 23 pairs is right and i also think that the rest is right to
Answer:
Western blot should be performed
Explanation:
Generally ELISA test is sensitive to elevated antibodies levels in the blood. Because HIV infection is characterise with increases in antibodies levels(HIV-antibodies levels)of the body, it is usually the first screening test for HIV,however it is also sensitive to elevated antibody from any other infection apart from HIV. Therefore for confirmation, the procedure is to run a second ELISA test, to determine if the antibody rise was due to HIV or not. If the second test turns positive, then Western blot can be applied.
The Western blot through secondary and primary antibodies binding , separates the investigating antibodies, and identity the specif HIV antibodies present to give a positive HIV-antibody, confirming ELISA positive test.
Thus for confirmation of HIV specific antibodies of the blood; ELISA test followed by Western blot is ideal
We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
The cell reaches equilibrium in a hypertonic solution by removing water from it so that the two concentrations are isotonic, in a hypotonic solution the water will move into the cell and in an isotonic solution the water will not move anywhere anymore. Both cells have the same solute concentration.
<h3>How do these equilibrium processes occur?</h3>
The hypertonic solution is the one that has a solute concentration greater than that of the cell, so in order to reach the same concentration, the water in the cell will leave to equal the solute concentration in the cell. The hypotonic solution, on the other hand, is the one that has a lower solute concentration than the cell, so the water will enter the cell to have the same concentration.
Finally in the isotonic solution nothing will happen, since both inside the cell and in the solution itself there will be the same concentration of solute, so no concentration has to be equalized.
Therefore, we can confirm that the cell reaches equilibrium in a hypertonic solution by removing water from it so that the two concentrations are isotonic, in a hypotonic solution the water will move into the cell and in an isotonic solution the water will not move anywhere anymore. Both cells have the same solute concentration.
