What is not utilized to culture viruses?

Explanation:

Cell culture is the process by which cells, whether prokaryotic or eukaryotic cells, can be grown under controlled conditions. In practice, the term "cell culture" is normally used in reference to the culture of cells isolated from multicellular eukaryotes, especially animal cells. The historical and methodological development of cell culture is intimately linked to the cultivar peptides of tissue culture and organ culture.

Animal cell culture began to be a routine laboratory technique during the 50,1 years but the concept of keeping living cell lines separate from the tissue of origin was discovered in the 19th century.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
