A client with suspected human immunodeficiency virus (HIV) has had two positive enzyme-linked immunosorbent assay (ELISA) tests.
victus00 [196]

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

What is plant blindness?
Komok [63]

Answer:

The answer is A.

Explanation:

Plant blindness refers to "the inability to see or notice the plants in one's own environment." The term plant blindness was coined twenty years ago by Elizabeth Schussler and James Wandersee who are botanists. Plant blindness results in "the inability to recognize the importance of plants in the biosphere and in human affairs." It is also the reason why people have a tendency of ranking “plants as inferior to animals”. Therefore, plants tend to receive limited care and upkeep. It is important to recognize plant blindness so that more intentional care can be given to preserving our plant species and ensure their survival and ability to thrive.
