Answer: The water will pass from 10% glucose to 75% glucose.
Explanation:
concentration wise, the solution from higher concentration will move towards the lower concentration.75% glucose has 75 of glucose and 25 of water similarly 10% glucose has 10 of glucose but 90 of water and as a result the glucose cannot pass but the water will pass from 90 towards 25.the movement may continue till the concentration of water on either sides becomes equal.
Answer: For detection and confirmation of HIV antibodies in blood samples.
Explanation: As the name implies ELISA( Enzyme-linked immunosorbent assay) is the first test widely used for determining the presence of HIV in a person's serum because of its high sensitivity. In an ELISA, a person's serum is diluted 400 times and applied to a plate to which HIV antigens are attached. If antibodies to HIV are present in the serum, they may bind to these HIV antigens. The plate is then washed to remove all other components of the serum. A specially prepared "secondary antibody" (an antibody that binds to other antibodies) is then applied to the plate, followed by another wash. This secondary antibody is chemically linked in advance to an enzyme.
Thus, the plate will contain enzyme in proportion to the amount of secondary antibody bound to the plate. A substrate for the enzyme is applied, and catalysis by the enzyme leads to a change in color or fluorescence. ELISA results are reported as a number; the most controversial aspect of this test is determining the "cut-off" point between a positive and a negative result. A cut-off point may be determined by comparing it with a known standard. Unknown samples that generate a stronger signal than the known or control sample or are called "positive" while those that generate weaker signal are "negative".
That is true. Women are generally smaller in body size, this also contributes to how affected women get by alcohol.
