Answer:
Explanation:
Let's think about this from a human perspective (humans are multicellular organisms).
Humans inhale oxygen to use in cellular respiration. Carbon dioxide is the waste product of the process and it is exhaled.
Humans consume proteins and make proteins in protein synthesis. They are used for all sorts of things such as: hormones, repairing tissues, catalysts, providing structure, and more.
So, clearly, the substance that is let out is<u> carbon dioxide</u>. It is exhaled as waste when we breathe, but proteins are used inside the body.
While using qualitative research methods, researchers often gather data in natural settings, such as where the person lives or works, rather than in a laboratory or other research setting.
<h3>What are qualitative research methods?</h3>

Qualitative research methods are classified according to the strategies used to obtain and collect data, which can include observations and interviews.
In conclusion, while using qualitative research methods, researchers often gather data in natural settings, such as where the person lives or works, rather than in a laboratory or other research setting.
