Question

which of the following statements violates the cell theory? a some scientists believe that prions, tiny proteins much smaller than a cell, may be living organisms. b mitosis produces new cells identical to the parent cell that divided to make them. c viruses are not considered to be living organisms, because they are smaller than a cell. d though humans are one organism, they are composed of about 100 trillion individual cells.

Explanation:

The cell - theory states that all living things are made of cells, cells are the basic unit of life, and all cells come from pre - existing cells. Prions are non - cellular entities. Believing them to be living organisms violates the cell theory which emphasizes the cell as the fundamental unit of life. Option B is consistent with the cell theory as mitosis is a process of cell division producing identical cells. Option C is a correct understanding about viruses not being living organisms and does not violate cell theory. Option D is also in line with the cell theory as it describes the cellular composition of a multicellular organism.

Answer:

A. Some scientists believe that prions, tiny proteins much smaller than a cell, may be living organisms
