What differs among dna structures of different species? a) the base pairs b) the nucleotide structure c) the types of amino acids used to make proteins d) the arrangement of the nucleotides within genes

It is the arrangement of nucleotide within the genes which differs among DNA structures of different species. Each gene contains several codons which is three nucleotide long. Several nucleotide are present in a DNA strand that is why we call it as polynucleotide. The sequence of nucleotide with in the DNA describes the sequence of mRNA and so is transcribed into proteins. Any change in the arrangement of nucleotide will change the final protein which is formed.    

what's the question?

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
