entering a host cell and making copies of itself

Viruses reproduce by infecting a host cell, and making it produce copies of a virus instead of antibodies. This is how viruses double in your body.

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.

answer; i believe the correct answer to the above question is ( friction)
