QUESTION: Can you think of a scenario in
which an experiment is set-up to
answer a scientific question that
might not contain a control
group?

(please help me this is due at 11 tonight)

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
