the median is in the middle therefore 174 cm

its either the 2nd or 3rd boxes as eukaryotes share the same ancestral form with another domain

because the crossing over happens above the B parts so they stay where they are only the As change :)
take whatever you want and give nothing back :)

for tests..

u need 2 knw only 2... t-test nd correlation test (i dnt knw  its others name)

t-test u use when u compare 2 things.. like u divide land 2 2 areas nd u compare between them

correlation is when there r dependend nd independent variables.. when something increases, other decreases (for example)..

got it?


I forgot to thank you! :D a belated thanks :P
