Answer:
For example, TH2 cells directly stimulate B cells to class switch, producing immunoglobulin isotype IgE, which is useful in targeting parasitic worms.
Explanation:
Immunoglobulin E, or IgE, is a protein present in low blood concentrations that is usually found on the surface of some blood cells, especially basophils and mast cells, for example.
Because it is present on the surface of basophils and mast cells, which are cells that normally appear in higher blood concentrations during allergic reactions, IgE is usually related to allergies; however, its concentration may also be increased in blood due to diseases caused by parasites. and chronic diseases, such as asthma, for example. This is because TH2 cells directly stimulate B cells for class switching, producing the IgE isotype of immunoglobulin, which is useful in targeting parasitic worms.

В. It is possible that your body weight is within the appropriate range, but your body composition is not.
Explanation:
The "BMI" or <em>"Body Mass Index" </em>is used in order to know whether the weight of a person is within the normal range. However, <em><u>it's not a real indicator for a person's body fat composition in the body.</u></em>
For example, a person within the normal weight may look healthy because his BMI is within the standard range; however, he may actually be fatty on the inside if his body composition will be checked. Another example are the weightlifters. They may seem heavy on the outside and their BMI are above the normal range; however, their body fat composition is low. So, this means they're healthier though they're overweight.
