Answer:
b. James-Lange theory
Explanation:
This theory perfectly explains her conditions because it is based on the emotions caused by external events. In the example, the external events were her brother interruption and her boyfriends phone call. The interruption produced an emotion of anger while the boyfriends call produced an emotion of love and happiness. The external emotions play a very important role and are crucial for the onset of proper emotions.
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".
When body releases Glycagon, It <u>increases the blood sugar/glucose levels.</u>(Option B)
The Alpha cells of the Pancreas secretes the hormone named Glucagon. It increases the blood sugar levels. If levels of blood glucose gets low, then α-cells secretes low glucagon. This can be treated with exercise and a protein diet which stimulates the secretion of glucagon.
- This hormones fits into receptor sites on cells membranes and activates the enzyme inside the cell which convert glucagon to glucose.
- The glucose then passes out of the cells and into the blood, raising blood sugar levels.
✒ Other than this hormone, the beta cells secretes the insulin hormone and delta cells secrete the growth inhibiting hormone (GHIH-somatostatin).
