Transcript

00:01 First part of the question is question number 18 and it is associated with diarrhea now in the question it mentions about diarrhea which is related to non -absorbable substrate or let's say which is generally fibers right so options given to us or even without going to options if we know that this fiber is non -absorable that means a body cannot digest it so it does non -digesting type so it will remain in your intestine as such so let's say we have intestines and this is the non -absorbable fiber so what will this fiber do is that it will increase the osmotic osmolarity in the intestine and your intestine will start to secrete h2o so h2 will be inside the intestine into increased amount of h2o this will lead to diarrhea right so answer to the question number 18 it is basically osmotic diarrhea which is given in option c become so that becomes correct answer in the next part question number 19th we have to tell which is correctly paired option a it mentions enteric fever in wbc so in case of infection like enteric fever the wbc count is generally low because wbcs they die of trying to fight of the infection.

01:39 Next we have herd immunity so option a it is incorrectly matched herd immunity is basically immunity of a group of people right it is not related to any animal it is immunity of group of people and if a certain amount of people they have immunity against a particular disease specifically against a communicable disease the spreading of disease can be prevented to a much greater extent.

02:13 Next we have acetylcholine or a c .h.

02:19 Blocker.

02:19 Now ach blocker they block the interaction of ach with its receptor.

02:25 So let's say this is the case.

02:28 Here we have the receptor and here we have ach.

02:36 A blocker will be something like same shape, but kind of different functionality.

02:42 So let's say this is the blocker.

02:44 This will simply go bind to the receptor so that actual substrate cannot bind it.

02:48 So either this mechanism or it might modulate receptor or it might, you know, promote the receptor mediated endocytosis or the receptor itself...
