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.

The correct answer is - marine organisms.
Both, the oil and the natural gas are formed on the basis of dead marine organisms. When the marine organisms were dying, they were falling in depths and onto the sea/ocean floor. The sea floor is covered with very soft sediments, and if they were not eaten by scavengers, or they have been covered with another layer of sediments, they have been relatively well preserved. As they were decomposing, the isolation, temperature, and pressure, managed to transform the dead remains of the marine organisms into oily sticky liquid that over time gained the characteristics that we see now in the oil and the natural gas.
Cellular respiration is a chemical oxidation-reduction reaction that provides the energy needed for a cell to function.C6H12O6 + O2 == CO2 + H2O (+ ATP)
The molecules involved in cellular respiration are:Oxygen O2: from the air we breatheCarbohydrate (glucose): represents a source of energyCarbon dioxide CO2: from glucose degradationATP: the energetic molecules used by the cell
And finally H2O.
Because all organisms are made up of cells and there are different types of cells which carry different functions.
