7. The scientific name of lion is _________
a) Panthera Leo
b) Panthera Tigress
c) Panthera Lion
d) Panthera leo
View Answer
Explanation: Biological names are Latinized and written in Italics. The generic epithet starts with capital letter while the second component specific epithet starts with small letter. Here the binomial nomenclature of Lion is Panthera leo but not Panthera Leo. Also, in Panthera Tigress the second component is written in capital letter which means that Panthera Tigress is not the answer. And in Panthera Lion the word Lion is not derived from Latin which reflects that Panthera Lion is also not the answer.
