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.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
