Several differences between DNA and RNA allow the cell to differentiate between the two molecules, ensuring that transcription and translation occur appropriately. Which is one of the
properties of RNA that differentiates it from DNA?
A RNA includes phosphate groups instead of nitrogenous groups.
B.
RNA is double stranded instead of single stranded.
C
C. RNA contains uracil (U) instead of thymine().
D.
RNA contains cytosine (C) instead of guanine (G).

answer: the answer is b

there’s no image attached but i can if you want: )

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
