False. An increase in temperature is an exothermic reaction. However, when a temperature decreases this is known as an endothermic reactionz
D. It has almost no hydrogen ions, therefore it is very basic.
Leah's experiment:
A. Takes careful and regular measurements (she measures the growth every day)
B. Has a specific hypothesis and a controlled experiment (the music is the only changing variable, the growth conditions are identical, and this is what she wants to test in her hypothesis)
C. Experimental data that can be recorded and analyzed (measuring the growth of plant fits this)
So the answer must be D, since there is no mention of past research that scientists have found on this topic.
The answer is predict, because it fits, and because someone can predict the outcome of something.
