Answer: becomes depleted of____
due to the overactive_____________
that are decomposing the surplus of
decaying organisms, which died due to the__________.
The bacteria use the oxygen for__________.

Explanation: Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants. The excess algae and plant matter eventually decompose, producing large amounts of carbon dioxide. This lowers the pH of seawater, a process known as ocean acidification.
So, in a RNA strand, there are nucleotides. Specific ones are always paired with specific other ones.
Adenine and Uracil are paired, and Guanine and Cytosine.
So basically, whenever you see a c, pair it with a G, and the same thing the other way around, and whenever you see an A, pair it with a U. In this case, the T's that have already been placed have to be paired with an A.
C. Nulceic Acids
Based on the molecular clock, we can see the changes over time in organisms and see how long they've been changing.
