Hurry best answer gets brainlest what did virchow observe that led him to determine one of the main components of cell theory? a. a cell splitting into two cells b. small “rooms” in cork c. plants that were composed of cells d. microscopic units making up parts of animals

I think the answer is a.

Rudolf Virchow observed A. a cell splitting into two cells. He was one of the scientists who contributed to the cell theory. He discovered that cells come from other cells, "cell division". 

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
