It may be perfectly healthy that their newborn is sleeping this long so unless they start displaying other strange symptoms that cause concern, there is no need to worry. They could suggest that they are concerned to the midwife if they feel anxious, to get a professional opinion.

VLD [36.1K]

Answer:

C

Explanation:

Iodine is used to test for starches. When iodine is placed in a solution with starch (non-reducing sugars) it turns blue-black color. When amylase, a starch, is mixed with saliva, it is ‘digested’ to glucose, a reducing sugar (the brown colour of the aqueous solution remains).

If the dna double helix in salmon contains 22% guanine, what is the percent of cytosine, thymine and adenine? express your answe
Oksanka [162]

Theoretically it is the Chargaff's rule which entails that the ratio of purines and pyrimidines are 1. So following that rule you can solve this question.

G (purine) = C (pyrimidine) and

A (purine) = T (pyrimidine)

So G + C  would be 28% and hence

A +C would be 72% i.e. 36% each.

Please note that their are certain modified bases besides these four are also there including methyl Cytosine, Methylated Adenine. But htese modification does not violate the Chargaff's rule and they follow standard Watson Crick base pairing.
