11、One challenge is that the environment in space is altogether different from that back on the Earth.In normal(6)_,plants grow upwards.However,because of the near(7)_ of gravity in space,there is no such thing as“up”or“down”.Another thing that(8)_ us is the safety of eating the vegetables grown in spa
