  • Question 1
    4 / -1

    Animals undergo an inactive stage during the winter known as:

    Solution

    • Hibernation is an adaptation which has evolved in certain group of animals to conserve energy by slowing down metabolism and keeping their body temperature low in winters.
    • Bats and bears are well known for hibernating. Some of the hibernating animals includes fish, frogs and turtles, snakes, bees, hedgehogs which have no way to keep warm during winter.
    • Hibernation helps animal to survive when there is inadequate food supply. Before entering into hibernating state an animal stores enough fat to consume it during hibernation.

    So, the correct option is 'Hibernation'.

  • Question 2
    4 / -1

    Which of the following is the basic unit of study of ecology?

    Solution

    Ecology is the study of interaction between living organism and their environment. The basic unit of study in ecology is organism.

  • Question 3
    4 / -1

     Xerophytes are mostly:

    Solution

    • xerophyte is a species of plant that has adaptations to survive in an environment with little liquid water, such as a desert or an ice- or snow-covered region in the Alps or the Arctic.
    • Succulent (a xerophyte) plants store water in their stems or leaves.

  • Question 4
    4 / -1

     A large regional unit characterised by a major vegetation type and associated fauna found in a specific climate zone constitutes:

    Solution

    • This is a large regional unit characterised by a major vegetation type and associated fauna found in a specific climate zone.
    • The biome includes all associated developing and modified communities occurring within the same climatic region, e.g., forest biomes, grassland and savanna biomes, desert biome, etc.
    • On a global scale, all the earth’s terrestrial biomes and aquatic systems constitute the biosphere.

  • Question 5
    4 / -1

    The plants of this group are adapted to live partly in water and partly above substratum and free from water:

    Solution

    • A helophyte is a plant that grows in marsh, partly submerged in water, so that it regrows from buds below the water surface.
    • Fringing stands of tall vegetation by water basins and rivers may include helophytes.
    • Examples include stands of Equisetum fluviatile, Glyceria maxima, Hippuris vulgaris, Sagittaria, Carex, Schoenoplectus, Sparganium, Acorus, Yellow flag, etc.

  • Question 6
    4 / -1

    Broad-leaved oak forests are found in:

    Solution

    • A broad-leaved tree is any tree that has wide leaves, rather than slim, needle-like leaves as found in conifers.
    • Most broad-leaved trees are deciduous, such as birch, elm, oak and maple.

    Therefore, the correct answer is option D.

  • Question 7
    4 / -1

    Organisms capable of maintaining constant body temperature are:

    Solution

    Homeotherms: Animals who maintain a constant internal body temperature across a wide range of environmental conditions. Most mammals and birds are homeotherms.

  • Question 8
    4 / -1

    Excessive aerenchyma is a characteristic feature of:

    Solution

    Aerenchyma present in hydrophytic plants which provides buoyancy to floating in water. 

  • Question 9
    4 / -1

    Cold-blooded animals fall under the category of:

    Solution

    • Ectotherms are so-called cold-blooded animal that is any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface.
    • The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
    • The body temperatures of aquatic ectotherms are usually very close to those of the water.
    • Ectotherms do not require as much food as warm-blooded animals (endotherms) of the same size, but most cannot deal as well with cold surroundings.

  • Question 10
    4 / -1

    Biological organisation starts with:

    Solution

    • Biological organisms starts with sub-microscopic molecular level like viruses, bacteria etc.
    • These organisms are unable to be seen by naked eyes without the help of microscope or even electron microscope.
