The illustration below shows DNA replication before cell division. Which best describes the role of the free floating nucleotides (A, T, C, G) in the illustration?

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.

is this for the e2020 class

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
