Arna differs from dna in all except which of the following ways?

a. the presence of uracil
b. the 5'-3' orientation of the polynucleotide strand
c. the sugar molecule
d. the number of different functions performed

B. the 5'-3' orientation of the polynucleotide strand .

The complimentary pairing of DNA molecules ensures 5' 3' and 3'[ 5 '  arrangement for correct pairing of purines and pyrimidine (Adenine E with thymine and cytosine with guanine) in opposite direction.  .

RNA only contains five prime and three prime only, but DNA contains both 5'3' and  3'5'.

i think it is dna, i'm not totally sure but i think it might be.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
