It happens in glycolysis. It gets broken down into two pyruvates and it happens in the cytoplasm.
        
             
        
        
        
Answer:
C.  Oceans are carbon sinks because they store more carbon than they emit.
Explanation:
Oceans are carbon sinks because they store more carbon than they emit. Most of the carbon is produced in the respiration process as well as burning of fossil fuels. This carbon moves to the atmosphere and dissolved into the ocean which is required by the vegetation of ocean. Due to this carbon, vegetation produced more food for the organisms. About 25% of all CO2 emissions are absorbed by the ocean. Source is the part of a plant where materials are produced e.g. leaves whereas Sink refers to the part of the plant where the substrate can be stored e.g. roots or stem for starch.
 
        
             
        
        
        
Reverse transcriptase use mRNA to
form DNA apex
Reverse transcriptase is a broad
family of enzymes that play a unique role in the flow of genetic information. The
synthesis of DNA from an RNA template through reverse transcription produces
complementary DNA. Reverse transcriptase use an RNA template and a short
primer complementary to the 3' end of the RNA to direct the synthesis of the
first strand complementary DNA, which can be used directly as a template for
the Polymerase Chain Reaction.
 
        
                    
             
        
        
        
The chemical tags that are attached to DNA, known as the epigenome, can potentially be altered by the environment. These tags change the amount of protein that is produced from the genes by making them more or less active.
- Traits are frequently influenced by environmental factors rather than genetics. Although not always. Sometimes a gene's DNA sequence or degree of activity is altered by the environment. 
 - The proteins that a gene produces can be replaced by either of these effects, which in turn impacts characteristics.
 - The nucleotide sequence of a gene may alter as a result of some harmful environmental influences. DNA strands, for instance, can be damaged by UV light. 
 - Certain pollutants, such as those found in plastic and cigarette smoke, can change how DNA bases behave chemically, allowing one DNA base to stand in for another.
