BIO 110, lecture 7
attended!! (it was about sperm)
fertilization = the x-ray panel from EVERY doujin. it's real. biology is canon
sperm is basically a tadpole doing parkour
only one gets in. the egg goes X and the losers bounce off
the two that bounced off left together. they're married now, I decided
zona pellucida = the egg's bouncer. same energy as me on MY bench behind the observatory (it has my E on it)
do mushrooms do this? no. spores. I knew that
lectures attended this semester: 0 1. this one. for research
would eat
it screams. real.
