Answer:

C

Each ribonucleotide also has a phosphate molecule in their 5’ carbon like DNA. It is this phosphate that bonds with the 1’ carbon of the next monomer to form a phosphodiester bond through a condensation process – that releases a water molecule.

Reasons why the queen is the most important in the hive.<br> (No LINK)
Alex

Answer:

I assume you are referring to bees?

Explanation:

From what I know and this is just surface level knowledge, she is the one who births the hive and usually designates their purpose once she has laid the eggs. She herself does not do much, she is just the one that the infrastructure of the hive follows in maintaining the hive itself. I hope this helps. Good luck!
