(a)Yeast is used in the production of
(ii) alcohol
Via a mechanism known as fermentation, yeast is used to manufacture alcohol. As a by-product, the yeast ferments the sugar or starch to produce alcohol.
(b) The following is an antibiotic
(ii) streptomycin
The antibiotic is streptomycin. The drug used to treat bacterial infections.
(c) Carrier of malaria-causing protozoan is
(i) female Anopheles mosquito
Female Anopheles mosquito, when bites patient of malaria, then the malarial parasite pass to mosquito through blood sucking
(d)The most common carrier of communicable diseases is
(ii) housefly
The housefly is the major factor in contributing communicable diseases. It is the most common fly species found in our houses. Housefly feeds and meets waste products and eatables. When it flies from wastes to eatables, it transports the pathogenic bacterial agents from wastes to eatables.
(e)The bread or idli dough rises because of
(iii) growth of yeast cells
Yeast is used as leavening agent in bread and idli making. Leavening agent or yeast converts sugars present in dough to carbon dioxide and derive energy from this reaction. Due to this, yeast cells grow and dough also expands.
(f) The process of conversion of sugar into alcohol is called
(iii) fermentation
Alcoholic fermentation converts one mole of glucose into two moles of ethanol and two moles of carbon dioxide, producing two moles of ATP in the process.
