they wouldn’t mix either way cs of the septum it asked for q and r which both have oxygenated blood

The answers because the valves prevent back flow of blood so prevents oxygenated blood returning back to lungs.

I lost marks like the diffusion one, and improvements to experiment, graph and last one. I’m paranoid that I’m gonna lose marks from the simplest questions. I reckon imma barely scrape an 8.

I said the yellow banana had excess to light so underwent photosynthesis so then it produced glosuce and that's why is was present
