Respiration: I am very fascinated on how respiration and how we take part in it. We take in oxygen provided by plants and breathe out carbon dioxide. Learning about this topic was a bit confusing but once I got it, it felt like I knew the world inside-out. This had me thinking of living organisms living in place other than Earth.
