The amount of water given to the tomato plants

The height to which to tomato plants grow

Explanation:

In an experiment, the dependent variable is the variable that the experimenter measures. It is the variable that responds to changes made to the independent/manipulable variable.

According to this question, students investigate how soil pH affects the height of tomato plants. The different pH each plant receives is the independent variable while the HEIGHT OF THE PLANTS that responds to the soil pH or that is measured by the students is the DEPENDENT VARIABLE.

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

not too sure but maybe in the hot springs.
