Shreya Mangesh Patwardhan from City International school Satara road branch, PUNE
Subject :NSO    Class : Class 8

Ans 1:

ARAVINDAN MANIKANDAN from NPS INternational, Singapore
Class : Class 8
Then option A should also be correct as it talks about fermentation

Ans 2:

B Krithika sulochana from Devi Academy senior secondary school, Chennai
Class : Class 8
Option C is the correct answer because yeast causes fermentation .Fermentation is an anaerobic process. In this process yeast converts sugar into alcohol and carbon dioxide. Lime water turns milky indicating the presence of carbon dioxide.

Ans 3:

Arnav Gangwar from DPS NOIDA, GAUTAM BUDH NAGAR
Class : Class 8
answer cant be A since during fermentation of sugar alcohol is produced and not lactic acid

Ans 4:

Ethel shiju from National Public School Indiranagar, Bangalore
Class : Class 9
Option a is wrong because yeast does not convert sugar into lactic acid.

Ans 5:

Pushkar Sonnekar from Ryan International School, Mumbai, Vasai East
Class : Class 8
I think that option A and C should be correct. Since option A talks about fermentation occuring which could be true considering that yeast is put into warm sugar solution. Option C is also correct since we know that one of the end products of fermentation is CO2 and lime water turns milky white when it is combined with carbon-dioxide.
