D Correct answer
Explanation

DNA contains the genetic information necessary for the synthesis of RNA and thereby all proteins necessary for the cell to function. RNA is a sequence of nucleotides that contain information for the synthesis of proteins. Deoxyribose is a sugar present in the nucleotides of DNA. Proteins are also provide  information. 

So, the correct option is  'Deoxyribose'

A good source of vitamins of B groups is 

  1. Carrot

  2. Fish oil

  3. Germinated seeds

  4. Egg yolk
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • A vitamin is an organic molecule that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism. 
  • Essential nutrients cannot be synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the diet.
  • Best food sources of vitamin B:     Whole grains (brown rice, barley, millet)
                                                         Germinated seeds.
                                                         Eggs and dairy products (milk, cheese)
                                                             Legumes (beans, lentils) etc.
    • Sprouting is the natural germination process by which seeds or spores put out shoots, plants produce new leaves or buds, or other newly developing parts experience further growth. Hence, A good source of vitamins of B groups is Germinated seeds.
    So, the correct answer is 'germinated seeds'.

    The vitamin which can be synthesized in the gut by bacterial action is

    1. Vitamin B$ _1$
    2. B$ _2$
    3. Vitamin B$ _{12}$

    4. All of the above
    Reveal answer Fill a bubble to check yourself
    D Correct answer
    Explanation

    In the large intestine, water is absorbed into the blood as the waste materials move through the colon. The symbiotic bacteria such as E. coli and Streptococcus faecalis, normally residing in the healthy human colon, feed on protein contents of chyle breaking them into amino acids which are absorbed into the blood. The colon bacteria also synthesize vitamins B1, B2, biotin, folic acid and K which are absorbed. They also convert bile pigments into brown pigments which give colour to faeces. 

    Thus, the correct answer is option D.
