|ALIEN MUTATIONS. Shown
right are 12 mutation chambers labelled A-L. Each of the four aliens on
the left passes through the three chambers directly to the right to finish
as the alien on the right (e.g. the alien to the left of A passes through
A, B, C to finish as the one to the right of C). Also, each of the three
aliens at the top passes through the four chambers directly below to finish
as the alien at the bottom.
Every chamber performs a mutation
and does so on one part of the body (e.g. makes head square). What does
each of the 12 chambers do?
