  • Question 1
    1 / -0
    The correct lists of the phylogenic hierarchy is
    Solution
    Taxon represents the taxonomic group of any rank. Each individual belongs to a hierarchy of taxa which are assigned taxonomic ranks. The seven essential ranks of taxa in descending order are the domain, kingdom, division/phylum, class, order, family, genus and species. Name of a species refers to the group of potentially interbreeding, morphologically similar individuals. A genus is a taxonomic rank that constitutes single species of the monophyletic group of species that share a sum total of characters, though they cannot interbreed. The family includes a group of closely related but reproductively isolated genera. A group of closely related classes, that share some common morphological features but are reproductively incompatible, constitutes phyla. 
    Therefore, the correct answer is option D.
  • Question 2
    1 / -0
    Mus in the scientific name of Mus musculus represents
    Solution
    The scientific names on the basis of the binomial nomenclature is described with the help of two words. The first epithet is known as the genus and the second epithet is known as the species. The scientific name of the mouse is Mus musculus, in which the Mus describes the genus and the musculus describes the species. 
    Thus, the correct answer is option D. 
  • Question 3
    1 / -0
    Several scientist gave different definition of species . One of those definitions, a population or group of populations whose members have the potential in nature to interbreed and produce fertile offspring. Which of the statement is related to this definition?
    Solution
    Species are the group of populations including the individuals that can interbreed to produce fertile offspring. This means species reproduce sexually as interbreeding is sexual reproduction; asexual reproduction does not include interbreeding of individuals where offsprings are produced from the single parent only.Thus, the correct answer is option A.
  • Question 4
    1 / -0
    The most distantly related organisms come under the category of
    Solution
    Species is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. So, the correct answer is option B.
  • Question 5
    1 / -0
    Which of the following sequences of taxa and the animal kingdom is correct?
    Solution
    In biological classification, the rank is the level of organisms (a taxon) which have similar characters are placed in a taxonomic hierarchy. The correct sequence of groups from most to least inclusive is Kingdom- Phylum- Class-Order- Family- Genus- Species. For example, human beings belong to Kingdom-Animalia, Phylum- Chordata, Class- Mammalia, Order- Primates, Family- Hominidae, Genus- Homo, Species- Sapiens. 
    Thus, the correct answer is option B. 
  • Question 6
    1 / -0
    The correct order of level of classification is
    Solution
    In the taxonomical hierarchy, The taxon Kingdom is followed by Phylum which is followed by Class, Order, Family, Genus and Species in that sequence. Organisms with increased similarities are placed in the lower categories.
    So, the correct answer is, 'Phylum, class, order, genus'.
  • Question 7
    1 / -0
    Two snails in the same class can also belong to which group?
    Solution
    Taxon represents the taxonomic group of any rank. Each plant and animal belong to a hierarchy of taxa which are assigned taxonomic ranks. The seven essential ranks of taxa in descending order are the kingdom, division/phylum, class, order, family, genus and species. Two snails in the same class may belong to different order, species, genus and family but to the same phylum. This is because phylum includes classes sharing common features and two snails of the same class may be further assigned to same or different order, species, genus and family based on their similarities and dissimilarities. Thus, the correct answer is option E.
  • Question 8
    1 / -0
    The classification of organisms into kingdoms has come under debate in recent years, which group gets more focus in the debate?
    Solution
    • The most accurate classification of organisms under 5 kingdom classification was given by R.H. Whittaker.
    • The 5 kingdoms included were Monera, Protista, Fungi, Plantae and Animalia.
    • Due to their relatively simpler structure and size, prokaryotes and simple eukaryotes have remained less extensively studied. It has only became possible after the advent of high power microscopes and crystallisation techinques that these organisms ca be studied and debated about.
    So, the correct option is 'Prokaryotes and Simple eukaryotes'.
  • Question 9
    1 / -0
    Which of these is the broadest category of an organism in biological taxonomy?
    Solution
    The biological system of classification has arranged the organisms at different levels or category. The broadest category is the kingdom which includes all the organisms of a particular group. For example, according to the five kingdom classification, there are kingdoms like monera, protista, fungi, plantae and animalia.
    Thus, the correct answer is option C. 
  • Question 10
    1 / -0
    Which one of the following is a correct way of writing a scientific name?
    Solution

    There are precise conventions to follow while writing a scientific name.

    1. The genus name is written first and species should be second.

    2. The genus and species names should always be underlined (while writing) or italicised (while printing).

    3. The first letter of the genus name is always capitalised and species name never starts with capital letter.

    Example: Meleagris or Meleagris,  gallopavo or gallopavo.

    Thus, the correct answer is option D.
