dear mertnation ,

please tell the weightage of this lesson for board exam-2011

Dear Student,

Please note that the weightage given to the three chapters viz Human health and diseases, Strategies for enhancement in food production and Microbes in Human welfare is 14 marks. So you can estimate that the weightage for the said chapter should be near about 5 to 7 marks.

Hope this answers your query.

All the best!!
