Most living things need the elotnout polnto
Phosphorous (P) to grow and
reproduce. However, strain of
bacteria has been discovered ling in
a lake in California that does not have
any phosphorus in it/Salentists
hypothesize thót the bacteria found a
way to use another similar element to
replace phosphorus, but they
disagree on which element the
bacteria are using. Some scientists
think that the bacteria are using
Arsenic (As), while others think the
bacteria are using Magnesium (Mg).
Based on your understanding of
elements and the periodic table,
which element is the bacteria most
likely using instead of phosphorus?
Support your claim with evidence
and reasoning,
