    • The bulges in Hydra are known as buds and the process of formation of a new individual from these buds is called budding.
    • Pupa is the life stage in the development of insects exhibiting complete metamorphosis that occurs between the larval and adult stages

    So, option A is the correct answer.
  • Question 2
    1 / -0
    Dolly, the famous animal was a:
    Solution
    Dolly was a female domestic sheep and the first mammal produced by cloning from an adult somatic cell and not by reproductive cell. It was cloned by using the process of nuclear transfer.

  • Question 3
    1 / -0
    Animals which give birth to the young ones are called _______.
    Solution
    Animals that give birth to their young ones are called viviparous. The young ones resemble their parents. Oviparous animals lay eggs while ovo-viviparous organisms produce eggs that develop and hatch inside the mother's body till they are fully developed and born alive. So, the correct answer is option B.
  • Question 4
    1 / -0
    _______ is the production of an exact copy of a cell of any living part or a complete organism.
  • Question 5
    1 / -0
    Which of the following points is correct?
    OviparousViviparous
    1.They lay eggs.1Give birth to young ones directly.
    2.Chances of survival of young ones are less.2Chances of survival of young ones are more.
    3.E.g. Whale and dolphins3E.g. Birds and frog
    Solution
    1 and 2 are the correct distinguishing points between oviparous and viviparous animals. Oviparous animals lay eggs and in oviparous animals, chances of survival of young ones are less as the females lay eggs in the open environment. Viviparous animals give birth to young ones and the chances of survival of young ones are more because the embryo grows inside the mother's womb, so the protection is more. 
    3 is not correct because whales and dolphins are viviparous animals while frogs and birds are oviparous animals.
    So, the correct answer is option C.
  • Question 6
    1 / -0
    Give the correct correlation.
    Oviparous : _______ :: Viviparous : ______
    Solution

    Crow, frog, lizard are oviparous animals whereas cat, dog and cow are viviparous animals.

    The correct option is A.

  • Question 7
    1 / -0
    In which stage of metamorphosis does a creature develops cocoon around it?
    Solution
    Cocoon is formed in the pupal stage of metamorphosis. This stage occurs after the caterpillar stage. When the caterpillar is fully grown it stops eating and becomes a pupa. The characteristic feature of the pupa stage is the development of a protective, hard covering that surrounds the insect, this surrounding protective coat is called a cocoon.
  • Question 8
    1 / -0
    Give an example of viviparous animals.
    Solution

    Females in viviparous animals give birth to young ones. Mammals, like whales, sharks, mice, humans are examples of viviparous animals. Frog and butterfly are oviparous animals.

    So, the correct answer is Human being.

    The correct option is A.

  • Question 9
    1 / -0
    Metamorphosis occurs in:
    Solution
    • All frogs go through a process called metamorphosis, in which they mature from their larval or tadpole, stage into adult frogs. 
    • Mammals (e.g. rabbit, man) give birth to their young ones and do not perform metamorphosis. Lizard belongs to the class of reptiles and lays eggs.
    Thus, the correct answer is option B. 
  • Question 10
    1 / -0
    Which of the given figure represents budding in Hydra?
    Solution
    Budding is the asexual mode of reproduction in which a new organism grows from a bud attached to the body of the parent and separates later on after maturing. In the process of budding, a bud develops as an outgrowth. In the case of Hydra, after the development of the mouth and tentacles, the bud detaches from the parent body and grows individually. 
    Thus, the correct answer is option C.
