what my teacher lectured for 5 hrs and couldn't explain well; this video did that in under 5 minutes. Thank You! Also, nice pokemon reference with shiny butterfree!
Thank you very much, only video where they do not mess up saying that the cones and rodes produce action potentials, but only just saying that they convert from electromagnetic to quemical energy. Thanks!
do you even have tears other than the basal tears produced when your sleepy? i dont think so because if either psychic or reflex tears were produced we would know. and the only thing that happens to my eyes when im sleep is them closing.
