  • Question 1
    1 / -0
    Which of the following is not the correct diagram depicting budding in Yeast ?

    Solution
    • As shown in the given diagram, buds formed on parent cell are usually smaller before separation.
    • Only when bud detaches from the parent body and it grows independently as a new individual or may remain attached to the parent body, forming a chain of cells. Thus, diagram IV is incorrect, 

    So the correct answer is option D.

  • Question 2
    1 / -0
    Birds are considered oviparous because _______.
    Solution
    • Ovipary is the phenomenon in which an adult organism reproduces and lays eggs which later hatch and give rise to young ones. 
    • Since, birds lay eggs they are known as oviparous.
    •  Flight or wing modifications are not related to the process of reproduction.
    So the correct answer is 'They lay eggs'.
  • Question 3
    1 / -0
    The process of regeneration of new individual of the same kind is called as
    Solution
    Reproduction refers to the process by which new individual organisms (offspring) are produced from their parent.
    Some animals like Planaria reproduce by regeneration. It is a type of asexual reproduction in which an organism is capable of regrowing certain body parts or the whole organism from different pieces.
    So, the correct option is 'Reproduction'.
  • Question 4
    1 / -0
    Pollination is
    Solution
    The transfer of pollen grain from the anther to the stigma of a pistil is called pollination. It is a mechanism by which non-motile male and female gametes are brought together for the fertilization. Following are the types of pollination:
    1. Autogamy: The transfer of pollen grain from the anther to the stigma of the same flower.
    2. Geitonogamy: The transfer of pollen grains from the anther to the stigma of another flower of the same plant. This transfer involved an agent of pollination, hence functionally it is cross-pollination. Genetically, it is similar to autogamy since the pollen grains come from the same plant.
    3. Xenogamy: The transfer of pollen grains from the anther to the stigma of another flower of different plants of the same species. This is the only type of pollination which brings generally different types of pollen grains to stigma.
  • Question 5
    1 / -0
    The process of propagation of new individual from the existing one is called as
    Solution
    • Reproduction refers to the production or propogation of new individuals by an organism. 
    • Syngamy of fertilisation refers to the fusion of gametes which may or may not be similar.
    • So, the correct option is 'Reproduction'.
  • Question 6
    1 / -0
    The word estrus means
    Solution
    The reproductive cycle of the non-primate females is called oestrous cycle. For example, in rats, horse etc. It can be divided into four phases proestrus, estrus, metestrus and diestrus. The word estrus means heat. It is a sign of sexual receptivity and fertility.
    So, the correct option is A.
  • Question 7
    1 / -0
    An animal either male or female is known as ________.
    Solution
    The animal which has either the male or the female reproductive organs are known as unisexual organisms. These organisms exhibit the property of sexual dimorphism. Sexual dimorphism are the differences in appearance between males and females of the same species. The lizards are the reptiles which are bisexual. There are no different sexes but both the sexes are present in the same organism. Humans are unisexual. 
    Thus, the correct answer is option A. 
  • Question 8
    1 / -0
    Calf grows?
    Solution
    Cow is a placental mammal. Once it gives birth to a calf it grows outside the cow's body.
    Young one of Kangaroo is known as Joey.
    So the correct answer is 'Outside the cow's body'. 
  • Question 9
    1 / -0
    A polyoestrus animal is
    Solution
    Estrous cycle is a reproductive cycle of females of non-primate vertebrates. The gap between two estrus periods is known as estrous cycle. The females are highly receptive during estrus period. It is an indication of breeding period because one or more periods of estrus may occur during the breeding season of a species. Polyoestrus are the animals which ovulates more than once in each breeding season. For example, rabbit. Cats are polyestrous but experience a seasonal anestrus in autumn and late winter. Horses are seasonal polyestrous. Humans have menstrual cycle they lack estrous cycle.
    So, the correct answer is option C.
  • Question 10
    1 / -0
    Fertilization is fusion of
    Solution
    Fertilization is the process of union of a haploid sperm cell with haploid ovum to form a diploid zygote.
    So the correct answer is 'Haploid spermatozoan with haploid ovum to form a diploid zygote.'
