Dna and rna differ in all but one of the following ways.
a)
dna is double-stranded, while rna is single stranded.
b)
rna uses the sugar ribose in its backbone, while dna uses deoxyribose.
c)
dna contains the base uracil, while rna contains the base thymine instead.
d)
dna is found in chromosomes in the nucleus, while rna can move around the cell.

The correct answer would be C) DNA contains the base uracil, while RNA contains the base thymine instead.

DNA, as well as RNA, are nucleic acids which are made up of nucleotides.

In DNA, the nucleotide is made up of deoxyribonucleic acid, a phosphate group and nitrogen base (adenine, guanine, cytosine, or thymine).

In contrast, ribonucleotide is made up of the ribose sugar, phosphate group and nitrogen base (adenine, guanine, cytosine or uracil).  

In addition, DNA is a double-stranded molecule whereas RNA is a single-stranded molecule.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
