(b) As a student of biology what do you feel are the advantages of giving scientific names to the Mango?

Q12. A student of taxonomy was puzzled when told by his teacher to look for a ‘key ‘to identify a plant. He went

to his friend to clarify what ‘key ‘the teacher was referring to. What would the friend explain to him?

What are the values exhibited by he and his friend?

a student of biology how would you make them realizes that the disease is not caused due to the displeasure

of the gods?
