question 18 of 25 according to cell theory, which activity is impossible? a. prokaryotes existing by themselves b. skin cells forming from sunlight c. liver cells forming from liver cells d. ribosomes being present in eukaryotes

Explanation:

Cell theory states that all cells come from pre - existing cells. Skin cells cannot form from sunlight as sunlight is not a pre - existing cell source. Prokaryotes can exist independently, liver cells can come from pre - existing liver cells through cell division, and ribosomes are normal components in eukaryotic cells.

Answer:

B. Skin cells forming from sunlight
