Just wondering, why is there subtitles for some of these clips but not all? Love your content, btw. I think your channel's going to be big!
ОтветитьI like the details you add, they explain so much.
ОтветитьDo all animals have to lose nitrogen compounds? They (we) take in nitrogen compounds as amino acids.

Even in chemical theory, could an animal recycle all nitrogen instead of taking some in and excreting some?
ОтветитьDo eggs need air since they can breathe? I wonder because turtles burry their eggs in the sand. Why don't they suffocate?
Ответить*waits for an official playlist to be made
