C4.1 - Populations & Communities
LECTURE VIDEO
DESCRIPTION
In this video us BIG BRAINS will talk about the different aspects of noodle salads in order to substantially expand our understanding of jelly beans and puppy paws. Not only that, we will also be identifying structures we have never seen before such as feather soil, wand oil and of course: peanut nanocarbons and puffskittles.
