Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The International Code of Biological Nomenclature is the set of rules and recommendations dealing with the formal scientific names that are given to plants and animals. 
  • Its intent is that each taxonomic group has only one correct name that is accepted worldwide. The value of a scientific name is that it is an identifier; it is not necessarily of descriptive value, or even accurate.
  • International code of Viral Nomenclature (ICVN) is applicable for viruses.
So, the correct option is 'Both B and C'.

Botanical names of plants are treated in Latin because

  1. Rules of nomenclature were framed by Italian botanists they were speaking Latin.

  2. It is very difficult to pronounce Latin names and they convey multiple meanings.

  3. Latin was the natural language of many European countries.

  4. Latin was a dead language, its word would convey precise meaning. It was the mother of all European languages and all the early botanical literature was in Latin.

B Correct answer
Explanation
  • The International Code of Zoological Nomenclature(ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of animals.
  • Rules for nomenclature according to ICZN are 1)It consists of two parts one is the genus epithet and the other is species epithet 2)The genus name is always written first 3)The genus name must be capitalized 4)The species epithet is never capitalized 5)The entire two-part name must be written in italics
  • Hence Homo sapiens is the correct depiction of ICZN because according to ICZN rules it has two parts one is genus epithet(Homo) and species epithet(sapiens), Both the parts are in italics, Genus name starts with a capital letter and species name starts with small later.
  • So, the correct answer is 'Homo sapiens'

  4. Discovery of blood circulation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  1. Carl Linnaeus, a Swedish botanist, physician, and zoologist, laid the foundations for the modern biological naming scheme of binomial nomenclature. He is known as the father of modern taxonomy and is also considered one of the fathers of modern ecology.
    2. The theory of biogenesis was proposed by Louis Pasteur. He proposed that all life originated from pre-existing life. i.e., fishes laid eggs giving rise to more fishes.
    3. The first optical microscope was invented by Zacharias Janssen.
    4. William Harvey is associated with the discovery of blood circulation.
    So, the correct option is 'Binomial nomenclature'.
