Using fire in lab OOF, we hated chemistry. Which terms refers to a reaction that releases energy (generally, in the form of heat)?
Isotope
Hyperbolic
Granulation
Exothermic
You're, like, big smart about this science stuff. Exothermic reactions often release energy as heat and, sometimes, as light too. The opposite of this process is an endothermic reaction which absorbs heat, thus cooling the surroundings.

Venus fly trap More plant stuff! Which science word means the response of a plant toward or away from stimulus?
Tropism
To plants (actually, to all of us), the Sun is life. There are a lot of stimuli, but it's pretty much the most important one. Have you ever seen an indoor plant growing toward a window? It's not that it has a mind of its own, but rather, the plant is exemplifying tropism.
Symbiosis
Nitrocellulose
Troposphere
