C. Scientific observations show that microscopic organisms living in the deep ocean are not made up of cells

Explanation: The cellular theory says that cells are the structural and functional basic unit of life, that all living organisms are made up of cells and that cells came from other cells. This theory should be modified if there's scientific observations that challenge the postulates: living organisms that were not made up of cells can't have cells as functional and structural units, for example.

The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

Viruses vary greatly in size and structure. Viruses are small particles which are neither living nor dead. they are having RNA or DNA and a protein coat. They have different size and structure. Viruses attacking bacteria called bacteriophages have complex structure and size.
