He could model tornadoes by controlling input parameters and analyzing the related outputs.
Explanation:
A tornado simulator is a device that allows a scientist to study the causes and effects that a tornado can cause in a region. With the tornado simulator it is possible to model variables that will allow you to control the events of a tornado taking place in a territory, allowing scientists to study these variables and make improvements to the environment that will allow the impacts of the tornado to be smaller. For this reason, we can conclude that the correct answer to your question is: " He could model tornadoes by controlling input parameters and analyzing the related outputs."
B. the creation of gene families, which are genes that are similar across a range of organisms. C. offspring becoming increasingly different from their ancestors.
