Answer:
D. seafloor spreading
Explanation:
If you explore two oceanic plates at a convergent boundary , you will observe seafloor spreading.
The hydrogen bonding of nucleotides into a new DNA molecule is facilitated by enzymes. Hydrogen bonding is the electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom, such as oxygen or nitrogen. The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pairs forms two hydrogen bonds while the C-G pair forms three. The enzymes called DNA polymerases join the nucleotides by way of phosphodiester bonds.
C. protein synthesis (they make proteins)
D because kg is mass and cubic cm is volume which Density = Mass / Volume
