Hi, everyone. Let's take a look at this question together. Select which statement is incorrect regarding antibodies. Is it answer choice. A antibodies when produced can attend to any future infections. Answer choice B antibodies are produced by plasma cells. Answer choice cigg is transferred from the mother to the fetus during pregnancy or answer choice. Dig A is present in the mucosal surfaces of the body. Let's work this problem out together to try to figure out which of the following answer choices contains an incorrect statement regarding antibodies. So in order to solve this question, we have to recall what we have learned about antibodies to determine which of the following statements is an incorrect statement regarding those antibodies. So starting off with answer choice A it says antibodies when produced can attend to any future infection. Well, we know that when those antibodies are produced, they cannot attend to just any future infection since antibodies recognize one specific antigen, so they cannot attend to just any future infection. For example, an antibody that recognizes the mumps virus cannot recognize the measles virus which would make answer choice. A an incorrect statement. So answer choice A is the correct answer. And we know that all other answer choices are incorrect as they all contain correct statements regarding antibodies. Since antibodies are produced by plasma cells, IgG is transferred from the mother to the fetus during pregnancy and IG A is present in mucosal surfaces of the body. So answer choice A is the only statement here regarding antibodies that is incorrect. I hope you found this video to be helpful. Thank you and goodbye.
