Question

the passage below describes an experiment. read the passage and think about the variables that are described. levi wanted to grow cucumbers from seeds. he read that using a heating pad to heat up potting soil could help make seeds germinate, or sprout, faster. levi wondered whether the temperature of the heating pad would affect how quickly the seeds germinated. levi prepared two potting trays, each made up of ten small pots of soil. he planted one cucumber seed in each small pot and arranged the potting trays near a sunny window. he set an electric heating pad to 75°f and placed it under one potting tray. he set a second heating pad to 85°f and placed it under the other potting tray. levi observed the pots daily, and he counted the number of days it took until a seed germinated in each pot. which of the following was a dependent variable in this experiment? the temperature of the heating pad the number of days until a seed germinated

Explanation:

Step1: Identify dependent variable

The variable that is measured as an outcome is the dependent variable. Here, Levi is measuring how long it takes for seeds to germinate.

Answer:

The number of days until a seed germinated
