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.

<u><em>Boreal forest
</em></u><em> is a large amount of carbon is being taken in by Biome</em>
Answer: C. Boreal forest
Explanation:
BOREAS is the investigation completed in the boreal woodland at Canada that spotlights on improving our comprehension of the radiant energy, heat, water, carbon dioxide and gases between the boreal forest and the environment.
An essential goal of BOREAS was to gather the information expected to improve the models of computer simulation of the significant procedures controlling these exchanges with the goal that researchers can envision the impacts of worldwide change on the biome.
