I found the rest of the exercise on the internet and these are the options.
"-Undifferentiated vertebrae throughout the body.
-One neck vertebra allowing up and down movement.
-Many neck vertebrae that allow for greater mobility.
<span>-Two neck vertebrae allowing up and down and sideways movement."

The <span>present-day organism with four limbs has a neck with several vertebrae that allow movements of rotation (mostly because of only two vertebrae at the top of the neck), and side way movements, as well as back and forth movements.</span>
Answer:
A molecular formula tells us what atoms and how many of each type of atom are present in a molecule.
Explanation:
If only one atom of a specific type is present, no subscript is used.
For atoms that have two or more present, a subscript is written after the symbol for that atom.
Molecular formulas do not indicate how the atoms are arranged in the molecule.
