Answer:
<em>The option D) 'Every cell has a nucleus that contains genetic material' is not a part of the cell theory.</em>
Explanation:
The cell theory has three main postulates which are:
- All living things are made up of a cell or different cells.
- All cells arise from pre-existing cells
- Cells are the basic unit of life.
The cell theory does not claim that every cell shall have a nucleus. The prokaryotes lack a nucleus yet still are living things. However, all cells will have genetic material in the form of DNA or RNA.

Answer and Explanation:
The columns of the periodic table are able to inform the number and type of connection that the elements can make. This is because the number of each column informs the number of electrons in the valence layer of the elements. The amount of electrons in the valence layer is what determines the amount and type of bond that the elements make. The elements in column 1, for example, have 1 electron in the valence layer and therefore will make 1 covalent bond. The elements of columns 15, as another example, have 5 electrons in the valence layer and will need to make 3 ionic or covalent bonds.
