Answer

<p> Nitrogen</p>

Explain

<p> The yellowing of a plant's leaves usually signals a nutritional deficiency, often a specific mineral ion. In plants, different leaf discolorations are often symptomatic of particular deficiencies. Yellowing, or chlorosis, is typically due caused by the lack of necessary chlorophyll for photosynthesis. A common mineral deficiency leading to this condition is a lack of nitrogen, as it's an essential component of chlorophyll and proteins. However, deficiencies in other essential minerals such as iron, manganese, or magnesium might also manifest as leaf yellowing. Therefore, the yellow discoloration of the plant's leaves alludes its substantial need for adequate or increased intake of one of these metal ions.</p>

A young researcher wants to test how well extremophiles, organisms that thrive in extreme conditions, live in different environments. She will do this by putting extremophiles of different species into different solvents. Because of limited lab space, she can run only one sample at a time, and each sample must remain undisturbed for 7 days. To reduce the total time needed to process all samples, the researcher decides to use two acidic solutions along with a control. The information below includes the extremophiles and the solvents the researcher will use in her tests.
