The correct answer is C. The temperature of the water
Explanation:
In an experiment such as the one described about the speed of snails in water, the manipulated variable is the factor or element that is manipulated on purpose. This means the researcher or researchers slightly change this element to compare how this affects another variable. In this context, the manipulated variable is the temperature of the water because researchers used three different temperatures (cool, room-temperature, and warm), and therefore they manipulated or changed this factor. Moreover, it is expected temperature affects the distance nails move, which is the main variable.

Active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.
<h3>What are active volcanoes?</h3>
Active volcanoes are geological formations that have regular cycles of eruptions, releasing liquid magma to the Earth's surface.
These eruptions are composed of rocks (or ash weathers) that generate fertile soils, but also may affect the respiratory airways.
Volcanic eruptions have devastating consequences for human populations and lead to destruction as well as societal collapse.
In conclusion, active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.
