  • Question 1
    1 / -0
    The scientific name for woodchucks Marmota monax and the scientific name for the long-tailed marmot is Marmota caudata. Which of the following statements describes the taxonomic relationship between the woodchuck and the long-tailed marmot?
    Solution
    From the given scientific names, Marmota monax and Marmota caudata, it is evident that they have a common genus of origin. They are evolved from the same genus, Marmota. This can be easily identified from the binomial nomenclature system where the genus name is followed by a species name. Genus name starts with a capital letter and species name with a small letter.
  • Question 2
    1 / -0
    Generic name 
    Solution
    The scientific name of a genus may be called as the generic name or generic epithet. It is always capitalized in both, plants and animals. It plays a pivotal role in binomial nomenclature, the system of naming organisms. 
  • Question 3
    1 / -0
    Viruses are denied a kingdom of their own because
    Solution
    Viruses are denied a kingdom of their own because they are not organisms. 
    Viruses:
    -are not made of cells and do not have cells,
    -cannot accomplish the basic tasks of living cells,
    -have no ribosomes to make protein,
    -have no cytoplasm,
    -cannot acquire energy or steal the host's energy,
    -cannot grow or reproduce by themselves or with other viruses,
    -do not respond to stimuli,
    -cannot maintain a stable internal environment.

  • Question 4
    1 / -0
    Group of similar organisms which can breed among themselves are called a
  • Question 5
    1 / -0
    Viruses are assigned to the kingdom_______________
    Solution
    A virus does not belong to any of the five kingdoms of life. Even more odd, a virus is not made up of cells. Viruses do not eat, they do not produce waste, nor do they do many of the functions that other living things do. In fact, the only thing they can do is reproduce.
  • Question 6
    1 / -0
    As a practical definition of species, one can say that they are a group of organisms characterized by all of the following except they
    Solution
    • Species, the basic unit of classification in the hierarchical taxonomic system. A species is a group of similar organisms sharing a common gene pool and interbreeding freely, producing fertile offspring. Species occur in the form of many interbreeding groups called populations.
    • A species don't interbreed with other species in nature, interbreeding of the organisms of same species produces fertile offspring,  whereas interbreeding of different species produces sterile offspring. For example, horses and donkeys can interbreed, producing mules. Mules can't reproduce because of horses and donkeys are not same species, while they are close enough to interbreed, their offsprings are sterile.
    • They remain isolated and can be distinguished from one another in specific characteristics.
    So the correct option is they 'Are incapable of hybridization with other species'.
  • Question 7
    1 / -0
    A group of organisms at any particular level in a classification system is called as
    Solution
    A group of organisms at any particular level in a classification system is called as Taxon. The term taxon has been introduced in 1948 which indicates the taxonomic group of any rank. Thus option C is the correct answer.
  • Question 8
    1 / -0
    When writing species epithets, it is sometimes permissible to abbreviate the ................. name.
    Solution
    When writing species epithets, it is sometimes permissible to abbreviate the Genus name. It means that the genus name can be written in a short form accompanied by the full species name.
    For example, Mangifera indica can be written as M. indica.
  • Question 9
    1 / -0
    Throughout the world, official species names are in
    Solution
    Throughout the world, official species names are in Latin. This has been widely accepted and has been termed as 'binomial nomenclature'. In this type of nomenclature, there are two parts for scientific names: Genus part and species part.
  • Question 10
    1 / -0
    The oldest level of taxonomic classification is
    Solution
    Genus was considered to be the oldest level of taxonomic classification. After the biological species concept, that defined species as the group of an interbreeding population, species was adopted as unit of classification.
    Hence, the correct answer is 'Genus'
