Answer:
Explanation:
Part a
Normal Phase Chromatography
In the normal phase chromatography, the eluting power is highest for the solvent which has the highest polarity.
So from the given solvents as Methanol, Dichloromethane and Ethyl Acetate
the relative polarities are given as
Methanol=0.762
Dichloromethane (methylene chloride)=0.309
Ethyl Acetate=0.228
So the numbers are given as
Methanol :1
Dichloromethane (methylene chloride):2
Ethyl Acetate:3
Reverse Phase Chromatography
In the reverse phase chromatography, the eluting power is highest for the solvent which has the lowest polarity.
So from the given solvents as diethyl ether , water and toluene
the relative polarities are given as
Diethyl ether=0.117
Water=1.0
Toluene=0.099
So the alphabets are given as
Toluene :A
Diethyl ether: B
Water:C
Answer:
The correct answer is <em>d. The nucleoside triphosphates have the sugar deoxyribose; ATP has the sugar ribose.</em>
Explanation:
The nucleoside triphosphates are components of DNA (deoxyribonucleic acid) so they are composed by a nitrogenous base (adenine, guanine, thymine or cytosine) and a deoxyribose sugar. In contraposition, ATP (adenosine triphosphate) is composed by the nitrogenous base adenine and a ribose sugar along with three phosphates groups. Unlike ribose, deoxyribose is a 5-carbon sugar which lack of an oxygen atom in C2 position.
Answer:
electrons
Explanation:
because it rotates the nucleus around it
Prokaryotes are organisms whose cells lack a nucleus and other organelles
