Biosphere because humans and animals live
Shleiden and Theodor Schwann were the first to recognize that all plants and animals are composed of cells.

The reason why it is much easier to read while shaking your
head rather than reading and shaking the page is because of the vestibular
ocular reflex, it is because when reading and shaking your head the vestibular
ocular reflex were able to respond faster than prolong and slow movements.
