I was wondering if what happened to Spider-Man can be applied to reality with scientific explanations. Being bitten by a spider with it's DNA transffered to his, is it possible? I thought that it's not that easy to transfer one's DNA to another and I don't think an individual will easily be immune to the foreign DNA. There might be effects but…

Real fiction or can be explained and done scientifically? What do you guys think?

The demodicid is a small worm like creature less than 0.4mm in length. Without them, our facial pores would clog up pretty bad.

I'm curious, given their tiny size, how is it that when we are born, we eventually pick them up? How do they ever find their way to my face? I feel quite positive that they don't crawl along the ground and up my leg and into my eyelashes.

I sure hope my mother didn't give me them... what a jerk!

are a) pollen or b)seeds ...structures that are produced by gynosperms and angiosperms that protect and nourish the embryo and sprout


my first thought was pollen, but angiosperms are all about seeds, so i don't know.

Fungi a)only "eat" dead matter so they are always decomposers b) may be saprophytic parasites or c)contain either DNA or RNA but never both

i definetly don't think it's C but again, I don't know

true or false
both plants and vertebraes have evolved in response to competitive pressure to move onto land

THANK YOU!!!
