Question

complete the sentences with the items provided.

1. antibodies are bound to the surface of mast cells and basophils and are involved in allergies.
2. antibodies are found in all body fluids and are the smallest but most abundant of the antibodies.
3. antibodies are found mainly in areas of the body such the nose, breathing passages, digestive tract, ears,
4. antibodies are the first type of antibody produced in response to an infection.
5. antibodies are found as surface receptors on most b - lymphocytes.

Explanation:

To solve this, we match each antibody type to its description based on immunology knowledge:

1.

The description is about antibodies involved in allergies and bound to mast cells/basophils. This matches IgE. (Already selected correctly.)

2.

Antibodies in all body fluids, smallest and most abundant: This is IgG. (The dropdown should be updated to IgG.)

3.

Antibodies in mucosal areas (nose, digestive tract, etc.): This is IgA. (The dropdown should be updated to IgA.)

4.

First antibody produced in infection: This is IgM. (The dropdown should be updated to IgM.)

5.

Surface receptors on most B - lymphocytes: This is IgD. (Already selected correctly.)

Final Answers for Each Dropdown:

1. IgE
2. IgG
3. IgA
4. IgM
5. IgD
