The correct formulae is CCl4
Huygens was writing about the theory of light.
"Eukaryote" roughly translates as "truly nucleated" and refers to organisms with a membrane-bound nucleus.
Such membrane-bound organelles are thought to have arisen via the invagination of the cell's own plasma membrane.
Other organelles such as the mitochondria and the chloroplast are believed to have once existed as separate organisms, but which were engulfed by other cells, forming a symbiotic relationship.
Cells know how to differentiate through a process called gene expression. It’s a specific combination of genes that are turned on and off.
