Answer:
The smallest living things are single cells, and cells are the functional units of multicellular organisms.
Explanation:
Based on the information provided within the question, from the answers provided the only statement that is one or the three parts of cell theory is that the smallest living things are single cells, and cells are the functional units of multi-cellular organisms. Which although phrased differently it is explaining that all living things are made up of cells, from the smallest one celled organisms to multi-cellular organisms like us.
The other two parts of cell theory are that all living cells come from pre-existing cells by a process called cell division and that the cell is the fundamental unit of structure and function in all living organisms. Which the other answers provided do not match.

The lining of your mouth is stratified but the lining of your small intestine is not because the primary function of the stratified lining is to protect the body when it comes to close contact to the outside environment.
The mouth has stratified squamous epithelia. This epithelia serves as protection of the mouth from mechanical or chemical abrasion, stress, <span>desiccation, and water loss.
The lining of the small intestine is not stratified because it has a different purpose. It is folded back and forth. This is to ensure that the small intestine has a larger surface area that can absorb nutrients.

In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. If there is no variation, then all individuals have the same chance to survive and nothing will be particularly selected.
