There is no option provided related to the experiment that is conducted to test the effect of pepsin under various conditions. However, answering the question will be easier if students understand the conditions under which pepsin works best. Pepsin will be active and work best in acidic conditions with pH values ranging from 1.5 to 2.5.
<h3>Why would pepsin work better in acidic environments?</h3>
Pepsin is a digestive enzyme that aids in the digestion of proteins contained in food. Pepsin is secreted by gastric chief cells as a dormant zymogen known as pepsinogen. Parietal cells in the stomach lining release hydrochloric acid, which lowers the stomach's pH. Pepsin is activated by a low pH, 1.5 to 2, and works optimally at pH 1.8 since the carboxylic acid group, which is located on the amino acid in the active site of pepsin, must be protonated, or connected to a hydrogen atom. At low pH, the carboxylic acid group protonates, allowing it to catalyze the chemical process of chemical bond breakdown.

For a few hours following the vaccination, "monitor your youngster for symptoms of an adverse response."
<h3>What is adverse response or an allergic response?</h3>
An aberrant immunological reaction is an allergy. The purpose of the human immune system is to defend against external threats, and in individuals with allergies, the immune system will react to allergens (substances that trigger an immune response).
Immune cells will make immunoglobulin E, or IgE, antibodies in response to each allergen. Histamine will be produced by body cells as a result of the antibodies. In order to cause symptoms of an allergic reaction, this histamine will operate on many bodily parts, including the eyes, throat, nose, gastrointestinal tract, skin, or lungs.
The allergic reaction is not constrained to a specific level of exposure. The immune system will respond each time the allergen is present if the body is repeatedly exposed to it.

Answer: the nurse will refer this child to a specialist for a bone marrow biopsy.
Explanation:
From the symptoms which where observed by the primary health care provider, the child had recurrent fevers, bone pain, and a recent loss of weight. While the physical examination revealed scattered petechiae, lymphadenopathy, and bruising. On further Laboratory diagnosis of the blood film, the full blood count revealed:
--> thrombocytopenia ( low platelet level)
--> anemia( lack of red blood cells) and
--> an elevated white blood cell count.
The major importance of full blood count is to evaluate the general health and detect a variety of of disorders. Since the blood picture is not normal, the health care provider should refer the child for BONE MARROW BIOPSY.
This is because the blood cells are produced from the bone marrow. Bone marrow biopsy is a test done to show if the bone marrow is healthy and able to make normal amount of blood cells.
The results of the bone marrow biopsy will help the primary care nurse to determine the cause of the abnormalities seen in the blood picture and will give the best directions to follow for an appropriate diagnosis and treatment.
