  • Question 1
    1 / -0
    Which of the following minerals are used for packaging of food items and minerals?
    Solution
    Aluminium is highly malleable thus it can form any shape. Aluminium foil provides a complete barrier to light, oxygen, moisture and bacteria. This protective quality has made it the most versatile packaging material for food items. It is also used for packaging minerals. Also, aluminium foil, aluminium cans and other aluminium packaging materials can be recycled and reused an infinite number of times. Thus the correct answer is option A.
  • Question 2
    1 / -0
    Which of the following is an advantage of occurrence of the water cycle? 
    Solution
    The water cycle has many advantages like it recharges ground water and water bodies. And sufficient rainfall is necessary for crops.
    The correct option is- 'All of the above'.
  • Question 3
    1 / -0

    Which of the following two statements is true?

    A. For conservation of natural resources like natural gas, one can get a tank-less water heater, as it reduces the usage of natural gas.

    B. To save natural gas, the use of another energy source like hydro, solar or wind power are all healthy alternative resources

    Solution

    Conservation of resources is nothing but making use of resources such that they are not depleted and are left behind for replenishing in future. This can be achieved in many ways, for example for conservation of natural resources like natural gas, one can get tank less water heater as it reduces the usage of natural gas and the other example is to save natural gas, the use of another energy source like hydro, solar or wind power can be followed.

  • Question 4
    1 / -0
    Identify the correct sequence of stages in the water cycle:
    Solution
    There are 3 main stages involved in the water cycle i.e. evaporation, condensation and precipitation. The water cycle starts with evaporation, where water is converted into water vapour form, followed by condensation, where water vapour converts into liquid form, and finally precipitation, where liquid water falls from the sky in form of rain, snow, hail, etc.
    Hence, the answer is option A.
  • Question 5
    1 / -0
    Which gas of the atmosphere holds up ultraviolet rays?
    Solution
    The ozone layer absorbs harmful radiations from the Sun and prevents those harmful radiations from reaching the surface of the Earth where they may damage many forms of life.
    The correct option is B.
  • Question 6
    1 / -0
    Humus is defined as
    Solution
    The bits of decayed living organisms present in the soil is called humus. 
    The correct option is C.
  • Question 7
    1 / -0
    Which one is not a free living nitrogen fixer?
    Solution
    The organisms involved in nitrogen fixation are termed 'nitrogen-fixing organisms'. They convert free nitrogen (gaseous form dinitrogen, $$N_2$$) into forms such as nitrates and nitrites that can be utilized by plants. These organisms could either be free-living or found in symbiotic, mutualistic, or commensalistic relationships with other plants.
    Rhizobium is found in a symbiotic relationship with leguminous plant roots. 

    So, the correct answer is option C. 
  • Question 8
    1 / -0
    The nitrogen content of the biosphere remains constant due to:
    Solution
    The nitrogen cycle is responsible for the nitrogen content in the biosphere to remain constant. In this cycle, the nitrogen passes from its elemental form in the atmosphere into simple molecules in the soil and water (nitrogen is fixed). The simple molecules get converted to more complex molecules when living beings consume them (plants take nitrogen from the soil, animals eat plants, and so on). When living organisms die, the complex nitrogen-containing molecules are converted back into simpler molecules in the soil (decomposition takes place). Microbes present in the soil, convert the simple nitrogen molecules into the elemental forms of nitrogen and release them into the air.
  • Question 9
    1 / -0
    The  most abundant element in the body of organisms and outside environment is____________.
    Solution
    Carbon is the element which is abundantly found in the organisms and outside environment.
    Nitrogen is present in most abundance in the atmosphere.
    Oxygen is essential for animals to survive and is next to nitrogen in abundance in the atmosphere.
    Hydrogen in a free sate is present in a lower quantity on earth but is majorly found in stars.
    Thus, the correct option is B.
