  • Question 1
    1 / -0
    Two morphologically similar populations are intersterile. They belong to
    Solution
    The two morphologically similar species may look similar but can be genetically different.  It may arise due to mutation variation and recombination. Mutation brings a sudden change in the nucleotides sequence. Variation and recombination lead to change in the genome. So if they reproduce they produce offspring which are inter-sterile as the gene flow is reduced within the population
    So, the correct answer is 'Two sibling species'
  • Question 2
    1 / -0

    Solution
    The Salarjung Museum is an art museum situated on the banks of river Musi in Hyderabad. It is one of the three National Museums of India.

It is primarily found growing along river banks below 900 meters. The temperature in its native range averages 10–40 °C. It can withstand average annual rainfall up to 2,000 millimeters (79 in) and droughts of 3–4 months. Thus, the correct answer is option A.
  • Question 4
    1 / -0
    "Systematics, is the study of diversity of organisms and all their comparative and evolution relationship", above statement is related to
    Solution
    G. Simpson in 1961 defined systematics is the study of the diversity of organisms along with the relationships among them. Derived from the Latin word "systema" this refers to the systematic arrangement of organisms. 
    Thus, the correct answer is option C.
  • Question 5
    1 / -0
    Which of the following arrangement is correct in ascending order?
    Solution
    The arrangement of taxonomy in descending order is as follows kingdom, phylum, class, order, family, genus, species.
  • Question 6
    1 / -0
    A scientific name contains information about its
    Solution
    A scientific name contains information about its genus and species.
    The scientific name of an organism is used to identify it anywhere in the world. Under binomial system of nomenclature, each organism has scientific name consisting of two parts. First part is genus and second part is the species. For example- the scientific name of mango is Mangifera indica, scientific name of house fly is Musca domestica.
  • Question 7
    1 / -0
    The broadest category of organism in biological taxonomy is 
    Solution
    The broadest category of the organism in biological taxonomy is a kingdom. 
    Each unit or category of classification is termed as a taxon. It represents a rank. For example, the basic level of classification is species, followed by genus, family, order, class, phylum or division, in ascending order. The highest level of classification is known as the kingdom. 
  • Question 8
    1 / -0
    The lowest taxonomic level is 
    Solution
    The lowest taxonomic level is species; it has maximum similarities.
    The fundamental unit of life on the Earth is what biologists refer to as the species.
    The biological species concept states that a species is a population or series of populations whose members are able to interbreed freely under natural conditions and who do not breed with other species.

  • Question 9
    1 / -0
    Which of the following is the correct sequence of the taxonomic hierarchy?
    Solution
    The correct sequence of the taxonomic hierarchy is
    (i) Kingdom
    (ii) Phylum (for animals)/Division (for plants)
    (iii) Class 
    (iv) Order 
    (v) Family
    (vi) Genus
    (vii) Species.
    So, the correct answer is 'Division, class, order, family'
  • Question 10
    1 / -0
    Binomial system of nomenclature means that every organism has
    Solution
    • Binomial nomenclature is the system of providing organisms with appropriate and distinct names consisting of two words, first generic and second specific. 
    • The first or generic word is also called the genus. It is like a noun and its first letter is written in the capital form.
    • The second or specific epithet represents the species. It is like an adjective. Its first letter is written in the small form except occasionally when it denotes a person or place. 
    So the correct option is 'One scientific name containing the generic and specific name'.
