Which of the following classes of antibodies is most likely to be made by the oldest plasma cell in a population of B cells?
a. IgM
b. IgG
c. IgA
d. None of the listed responses is correct.
Answer:
c. IgA
Explanation:
Specialized white blood cells called B lymphocytes (or B cells) contain antibodies. The mature B cells, or plasma cells, secrete millions of antibodies into the lymphatic system and the bloodstream. The plasma cell antibodies have the exact same antigen-binding site and specificity as the precursors to their B cells. Five different types of antibodies are present in humans: IgA, IgM, IgG, IgD,IgE.
In the oldest plasma cell igA classes of antobodies are present because initially plasma cells secret IgM but it switch and forms IgG, as the plasm aget older ans switch of antibodies takes place for scond time they can make IgA or IgE.
Hence, the correct option is c. IgA.
Answer:
Calcium
Explanation:
Between Neon and Calcium, neon will be more stable compared to the calcium.
Neon belongs to the group of elements on the periodic table called the noble gases. These are the most stable elements and they do not react with other elements.
- Calcium on the other hand is reactive
- It requires a loss of two electrons to attain stability.
- Therefore, it is a more reactive element.
Given what we know, we can confirm that Anthropologists deploy the method of ethnohistory to study cultural change in periods for which a community had no written histories.
<h3>What is Ethnohistory?</h3>
Ethnohistory is a method of study used by professionals such as anthropologists. This method uses a collection of historical records to produce data on previous civilizations and cultures.
Therefore, we can confirm that Anthropologists deploy the method of ethnohistory to study cultural change in periods for which a community had no written histories.
