The development of different cell technologies has led to changes in existing information. which of the following is an example of a discovery that could cause such a change?
a-an experiment that confirms how water moves into and out of a cell
b-an experiment that shows a different way to measure a variable
c-an experiment that reproduces the results of a previous experiment
d-an experiment that reveals a new step in a metabolic pathway

The most appropriate answer would be D-an experiment that reveals a new step in a metabolic pathway.

The discovery of a new step in the metabolic pathway would add on to the existing information.

It would help in better understanding of the process such as any disease or disorder related to the discovered step, enzymes used in the step, importance of the step et cetera.

Ultimately, it would help in developing new technology, process,  or medicine related to the discovered step.

i do not know and i have a 100 in this class

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.
