Answer:
B The host cell receptor is CD4 which the viral spike protein GP120 will bind to.
Explanation:
In HIV binding and entry, the HIV protein envelope, glycoprotein GP120 binds to the host primary cellular receptor CD4 to fuse to the host cell membrane and then initiate infection.
The virus presents itself as viral membrane spikes (molecular mimics of host molecules), these spikes consist of three molecules of gp120 which are linked together and anchored by gp41 protein to the membrane. The gp120 then binds to CD4 receptor of the host cell to facilitate viral entry int the host cell and further illicit other responses that lead to infection and dominance.
Answer:
Lower right quadrant of the abdomen
Explanation:
The symptoms of appendicitis can be varied but difficult to detect in young children or women of childbearing age.
The first and most noticeable symptom is abdominal pain. This pain begins being vague to progressively become acute and severe.

This client's jaundice can be explained by an obstruction of the common bile duct caused by pancreatic cancer.
<h2>
Jaundice</h2>
Because of elevated bilirubin levels, jaundice, also known as icterus, causes a yellowish or greenish coloring of the skin and sclera. In adults, jaundice is usually a symptom of underlying illnesses such as aberrant heme metabolism, liver malfunction, or biliary-tract obstruction. Jaundice is uncommon in adults, but it is frequent in babies, with an estimated 80% of them experiencing it during their first week of life. Itching, pale feces, and dark urine are the three most prevalent symptoms of jaundice.
In this client's case, the abnormal pancreatic neoplasm has obstructed the common bile duct, which causes the bile to accumulate in the liver and thus rises bilirubin levels in the blood.
