A group of five members spent in a room with dust. One among them shows some allergic responses. Name the chemicals released during allergy and which cells produce them.

What is the role of histamine in inflammatory response? Name few drugs which reduce the symptoms of allergy.

Monosaccharides containing an aldehyde group are called aldoses while those containing aketo group are called ketoses. The aldehyde group is always present at C_1 while the keto group is usually present at C_2 . All monosaccharides containing five and six carbon atoms have cyclic structures, furnaose (five membered) and pyranose (six membered). During ring formation, C_1 in aldoses and C_2 in ketoses becomes chiral and hence all these monosaccharides exist in two stereoisomeric forms called the alpha -anomer and the beta -anomer while C_1 and C_2 are called glycosidic or anomeric carbon atoms. In contrast, stereoisomers, which differ in configuration at any other chiral carbon other than the glycosidic carbon are called epimers. Two molecules of the same or different monosaccharides combine together through glycosidic linkage to form disaccharides. All monosaccharides (aldoses and ketoses) and most disaccharides reduce Tollens'reagent and Fehling's solution, undergo mutarotation and form osazones. Which of the following pairs give the same osazone?

In a class room discussion a student argues that allergic diseases are more common in children of metro cities than in villages Suggest two drugs which reduce allergic symptoms.

Read the following statements carefully and select the appropriate option given below. (i) Reproduction is defined as a biological process in which an organism gives rise to the young ones (offspring) similar to itself. (ii) Adventitious buds arise from the notches present at margins of leaves of Bryophyllum. (iii) Asexual reproduction is common among single celled organisms, and in plants and animals with relatively simple organisations. (iv) A few plants exhibit unusual flowering phenomenon, some of them such as bamboo species flower only once in their life time, generally after 50-100 years. (v) The events of asexual reproduction though elaborate and complex, follow a regular sequence.
