Humans are made up of trillion's of cells that have special jobs in order to work
together. This way they have a better
chance of surviving.
Our cells can’t survive
independently

JQ: When scientists first attempted to make an
avatar they were unsuccessful. After further
inspection they realized that a virus snuck past its
immune system and into its cells. Once in the cell it took over and destroyed the cells. Scientists think
that the avatar’s cells were missing an organelle.
Which organelle was most likely missing from the
avatar’s cells?
