Delicious77 [7]

Answer:

C. Diabetics will have ample supplies of insulin that are produced by bacteria.

Explanation:

The technology of recombinant DNA has allowed scientists to introduce the human insulin gene into E.coli bacteria. E. coli are thus turned into "biological factories" that produce large quantities of human insulin, which can be easily purified and used as medicine for diabetics.

There are many more examples of DNA recombinant technology in human medicine, such as the production of recombinant human growth hormone (hGH) also in E. coli that is injected in individuals who don't produce enough hGH naturally, or even the production of vaccines by inserting antigen-coding DNA into a cell, purifying it and later injecting it into individuals to stimulate immunization.

You are awaiting the white blood cell differential results for a patient who presented with a ruptured appendix and peritonitis.
vovangra [49]

Answer:

Neutrophils

Explanation:

In this case of a ruptured appendix and peritontis, the neutrophils are more likely to be elevated above normal value because:

1. They are the most abundant white blood cells (WBCs), about 60%-70% of the total white blood cell count.

2. they help to defend the body against fungal and bacterial infections and heal tissues that are damaged. The most likely infection to occur from a ruptured appendix is a bacterial infection.

Other WBCs like eosinophil is involved in parasitic infection; basophil is involved in allergic reaction; while monocyte is involved in phagocytosis.
