<em>Davy made a model of the water cycle by adding some water inside a plastic bag, sealing the bag, and placing it in a sunny area. He noticed that the level of the water went down, and then some droplets appeared on the sides of the bag. which part of the water cycle caused water droplets to form on the side of the plastic bag? </em>
<em>(a) condensation (b) evaporation (c) precipitation runoff</em>
The part of the water cycle that caused water droplets to form on the side of the plastic bag would be condensation.
<h3>What is condensation?</h3>
It is a process whereby water vapor in the atmosphere condenses or turns back into liquid.
Condensation is as opposed to evaporation. The latter is a process whereby liquid water turns into vapor water. In other words, evaporation and condensation are words and opposites.
Both processes play a major role in the water cycle of the ecosystem.

Well I dont know exactly how you modeled your model in this activity (also, I notice this is a question from 2016), but I do know the two processes.
This is the process of making glucose in plants. Photosynthesis goes through two individual stages:
Stage 1: L<span>ight dependent reaction</span> (depends on the presence of light; it can’t happen in the dark)
Stage 2: Light independent (dark reaction) (works in the absence of light, but calling it a dark reaction might be misleading; It can just as well happen in the presence of light).
