Which of the following correctly summarizes the main issue with most genetically engineered food crops? resulting crops are less nutritious creating a market for the resulting crops has proven difficult increasing one quality in a food crop may degrade other qualities resulting crops are too expensive because of the engineering

hello which   of the following there is nothing!

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.
