The sequence of mRNA for a DNA strand AACGTAACG will be UUGCAUUGC.
Central dogma can be described as a process by which information in the DNA is transcribed into mRNA and then changed into proteins.
For a strand of DNA, a complementary mRNA strand is made in order to decode the information in this strand of DNA into mRNA.
The pairing is done as follows: Adenine pairs with Uracil, and Guanine pairs with Cytosine for forming the mRNA transcripts. The nucleotide thymine is absent in mRNA.
Hence, for the strand AACGTAACG, the mRNA strand will be UUGCAUUGC.

Answer:
New cells are spontaneously created from existing cells
Explanation:
In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:
1) Cells are the fundamental and basic unit of all life and structure.
2) All living organisms are made up of one or more of these cells.
3) New cells arise from already pre-existing cells.
These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.
Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.
Then the submerged aquatic plants will note be able to receive light for photosynthesis. then those submerged aquatic plants will not have food/nutrients to survive, hence die. aquatic animals will not receive sufficient oxygen from those submerged aquatic plants, hence die also.
decomposes will breakdown all dead organisms to release carbon dioxide, and also deplete oxygen concentration during decomposition process.
eventually, habitat is rendered not livable. only the algae continue to proliferate uncontrollably at the water body surface.
