The one advantage of using DNS assay to detect maltose production is the formation of a soluble and colored product compound.
The reaction that occurs between maltose and DNS in the assay is a redox reaction (reduction and oxidation) such that maltose gets oxidized and becomes Maltonic Acid while the DNS gets reduced into reduced DNS. The intensity of orange/brown /red color of reduced DNS is proportionately related to the amount of Maltose in the solution.
Valence shell
The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
For the answer to the question above, I believe that <span>the mutation is likely in any type of regulatory sequence.The mutation is probably acting to reduce or prevent transcription initiation.</span>
I hope my answer helped you in some ways.
Your answer is burning gasoline. if you think about it, none of the rest of the answers really involve chemicals. ice isnt known as a chemical, and so isnt glass. and if your dent a bumper, it doesnt make sense to add it as a chemical change. so your answer is burning gasoline. hope this helps.
B. Without enzymes, chemical reactions would not occur quickly enough to sustain life.
