  • Question 1
    1 / -0
    Forelimbs of whales, bats, humans and cheetan are examples of which of the following processes?
    Solution
    Homologous organs are those which have a similar structure but perform different functions. The forelimb of a whale, bat, human, and cheetah are homologous. Divergent evolution is the evolution of organisms from a common ancestor. The presence of homologous organs in these organisms indicates that they have a common ancestor. 
    Thus, the correct answer is option A.

  • Question 2
    1 / -0
    Archaeopteryx lived during
    Solution
    Paleontologists observe archaeopteryx as a transitional fossil between dinosaurs and modern birds.

It belongs to the genus of bird-like dinosaurs.
    So the correct option is 'D'.

    Solution
    In human evolution, there are four main stages in the origin of man. These are ape stage, ape-men stage, primitive men (prehistoric men) and modern man. Ape stage includes Propliopithecus and Dryopithecus. Ape-men stage includes Ramapithecus, Kenyapithecus and Australopithecus. Primitive men includes Homo habilis, Homo erectus, Homo neanderthalensis. Modern man includes Homo sapiens fossilis and Homo sapiens sapiens. 
    Thus, the correct answer is option C.

    Solution

So, the correct answer is "Anthropology".
  • Question 6
    1 / -0
    Golden era/age of reptiles is
    Solution
    • Proterozoic Era (2500-544 mya) - Marked by the origin and proliferation of first eukaryotic organisms. Soft-bodied organisms were present.
    • Palaeozoic Era (544-245 mya) - Multi-cellular organisms acquire hard body parts - including teeth, bone, mandibles and vertebral column. Occurrence of first fishes, chordates, amphibians, reptiles and complex vascular plants. End marked by major extinction of invertebrates.
    • Mesozoic Era (245-65 mya) - Commonly known as "Age/ Era of Reptiles" or "Age/ Era of Dinosaurs" as the era began with the diversification of reptiles after major extinction and the appearance of dinosaurs. It is the age when giant reptiles and dinosaurs roamed around the Earth. It is also marked by the appearance of first mammals, birds, primates and the flowering plants. The era end by a major extinction causing disappearance of dinosaurs. 
    Thus the correct is 'Mesozoic'
  • Question 7
    1 / -0
    How many years are considered in one minute in Geological clock?
    Solution
    According to geological clock one minute corresponds to $$3,125,000\ years$$.

  • Question 8
    1 / -0

    Solution

    So, the correct answer is 'Reptiles'

    Solution
    Dinosaurs are a diverse group of reptiles of the clade Dinosauria. The Jurassic Period was the second segment of the Mesozoic Era. It occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period. The arid, continental conditions characteristic of the Triassic steadily eased during the Jurassic period, especially at higher latitudes; the warm, humid climate allowed lush jungles to cover much of the landscape. Gymnosperms were relatively diverse during the Jurassic period. So, the correct answer is "Jurassic".
