Question

Which one of the following organisms is scientifically correctly named, correctly printed according to the International Rules of Nomenclature and is correctly described?
A.Musca domestica – the common house lizard, a reptile
B.$Plasmodium falciparum$ – a protozoan pathogen causing the most serious type of malaria
C.felis tigris – the Indian tiger, well protected in Gir forests
D.E. coli – full name Escherichia coli a commonly occurring bacterium in the human intestine.

Answer 1

Hint: According to the rules of International Rules of Nomenclature, a binomial nomenclature for the scientific names of any organism should consist of the genus and the species. The genus name should start with the capital letter and species name should be normal or all alphabets should be in lowercase. Both the words should be Latinized or underlined if handwritten.

Complete step by step answer:
-Musca domestica is an example of common house fly, not reptiles. The scientific name is not in italics so option A. cannot be correct.
-$Plasmodium falciparum$ is a protozoan pathogen that causes the most serious type of malaria in humans and is carried by female Anopheles mosquitoes. Here the scientific name is in italics with the first alphabet of the genus in capital letter.
-Felis tigris is the taxonomic name of Indian tiger that is protected in Gir National Forest, Gujarat, India. In the given option, the first letter of genus is not written in capital letters. So, the option is wrong.
-Escherichia coli is the full name of E. coli and it commonly occurs in the intestine of humans. The scientific name is not in italics so the option is wrong.

Hence, the correct answer for this question is option B. Plasmodium falciparum – a protozoan pathogen causing the most serious type of malaria.

Note:
The binomial nomenclature was first introduced by Carl Linnaeus to name the organisms by using the genus and species name.
