Arabidopsis thaliana is a small angiosperm related to mustard.It is commonly used in plant research experiments.In one such experiment,an antifreeze protein from a species of bacteria was inserted into the genome of Arabidopsis thaliana,and the plants exposed to freezing temperatures.Plants without the antifreeze protein had 90% mortality,while those with the antifreeze protein only had 20% mortality.What was the dependent variable in this experiment?

Question

Quizplus · Accepted Answer

The dependent variable in this experiment is the percent of plants surviving after exposure to freezing temperatures. This is the variable that is affected by the presence or absence of the antifreeze protein. The temperature and the presence of the antifreeze protein are independent variables, while Arabidopsis thaliana and the bacteria are not variables in this experiment.
