Homework ✨️(=^ェ^=) ❤MCQ- (b) Malaria ❤Give Reasons for the following:- 1). Fresh milk is boiled before consumption in order to kill microbes whereas processed milk is not because it has already been pasteurized. 2).Raw veggies are kept in refrigerator to protect them from spoiling because the growth of microbes is retarded at low temp whereas it is not done with jams and jellies because they already contain a lot of sugar and sugar reduces the moisture content , so it does not get spoiled. 3). It is because beans and peas are leguminous crops which have a nitrogen fixing bacteria named rhizobium in their root nodules which fixes nitrogen. 4).It is because mosquitos breed in stagnant water. ❤Observe the fig........ :- a). Bread mould; fungi b).Bread c). Moist d). No ❤Observe the set up.... :- a). It will turn into alchohol b). Carbon dioxide c). It will turn milky A). Covid 19, AIDS B). Virus have no cells of their own they are dead but when they enter the body of any living being they become alive again.
