    (4) Calorie
6. The process of converting sugars into alchohols is known as 
    (1) Pasteurization
    (2) Sterilization
    (3) Homogenization

    (4) Fermentation
7. One of the main limitations of the Project method of teaching Science is that
    (1) knowledge is not acquired in a sequential manner
    (2) integration of concepts in various subjects can be achieved 
    (3)
the students have to perform excessive mental and physical work
    (4) it is a psychological method
8. Summative Assessment in Science should mainly focus on 
    (1) assessing observation skills
    (2)
diagnosing the areas of learning difficulties of students
    (3) tesing of mainly the practical skills

    (4) testing important theoretical concepts

      Summative assessments are provided at end of a unit to determine how much students have learned.
      Summative assessments provide information for determining grades and giving students feedback on 
      their performance. Such assessments are useful for making final judgments about student achievement
     and instructional effectiveness.

9. The dietary fibres are
    (1) made up of collagen fibres
    (2) made up of protiens
    (3)
also called roughage

    (2)
pitch decreases but loudness increases
    (3) both pitch and loudness of sound produced will decrease
    (4) both pitch and loudness of sound produced will increase

      Sound is a wave and waves have amplitude, or height. Amplitude is a measure of energy. The more 
      energy a wave has, the higher its amplitude. As amplitude increases, intensity or (loudness of sound)
      also increases. For most practical purposes the pitch is just the frequency of sound. Pitch is measured 
      in frequency of sound vibrations per second. If the frequency (i.e rate of vibration) is decreased, the
      pitch also decreases.

    Can u plz send me the answers of Maths n Hindi also of Second paper?? My mail Id is pachauri44@gmail.com

  2. Que 77 set q - Ans is 3 says:

    Thank for providing answers.
    In my view sodium and potassium are minerals…….
    calcium is correct but iron is not.

  3. MANISH says:

    23. The minerals that are required in the right amount for proper functioning of muscles are
    (1) Iodine and fluroine
    (2) Iron and Iodine
    (3) Iron and Calcium
    (4) Sodium and potassium

    i guess answer is 4- (4) Sodium and potassium

    • Naren says:

      @Manish
      Sodium and Potassium is best answer for functioning of Nerve.
      Potassium, along with sodium, works to regulate fluid in the body.
      Potassium also helps to maintain a regular heartbeat and low blood
      pressure.
      Calcium is a cellular cement for bones and it contributes to proper
      blood clotting in body. Calcium inhibits iron absorption from non-meat
      sources.Iron is required for the production of haemoglobin and myoglobin,
      which carries oxygen to our muscles.

      • Deepali says:

        In question it is “The minerals that are required in the right amount for proper functioning of muscles are” They have asked about minerals in right amount. I think that sodium and potassium should be the right answer.

      • Naren says:

        @Deepali

        i already put a comment in support of my ans. Anyway for
        more clearification again here, i am writing two more lines

        Iron is a vital element for muscle health…
        It is present in the muscle tissues as a
        part of myoglobin and helps in supply of
        oxygen required for contraction of muscles.
        for more details …search it on google

        regards
