Evaporation of water from the oceans.
Answer:
<h2>B</h2>
Explanation:
Glycolysis is the process of production of pyruvate from glucose by various enzymatic steps.
This pyruvate is further used in different ways; as it is differently used in the presence of oxygen or in the absence of oxygen.
In the absence of oxygen, lactate is generated form pyruvate, as given here, if this enzyme is non-functional, then lactate would not be produced.
In the presence of oxygen, pyruvate is oxidized in TCA cycle and finally through electron transport chain, energy in generated.
Carbon dioxide will be the answer
Explanation:
influenced by aquatic life, the heart & 2 lungs are because scientists believe when the water became over populated with life, some were able to reproduce on land..(Darwin's theory of evolution)...
Messenger RNA (mRNA) is the type of rRNA that carries the code from the DNA molecule to the site where the protein or polypeptide is synthesized.
What is the process of synthesis of mRNA?
Transcription is the process of copying a segment of DNA into mRNA in the presence of an RNA polymerase enzyme. It carries the DNA genetic information used to encode a protein.
What is the process of synthesis of protein?
Translation is the process of synthesis of protein where the information encoded in messenger RNA directs the addition of amino acids during protein synthesis.
Through the process of RNA splicing introns (noncoding sequences) are removed from the pre-mRNA and leaving exons (encode the protein). The mature mRNA before the completion of splicing enters into the cytoplasm where it was modified by the process of capping and tailing.
Capping involves the addition of unusual nucleotide methyl guanosine triphosphate to the 5 prime ends of the heterogeneous nuclear RNA.
Tailing involves the addition of adenylate residues to the 3 prime end of the hn RNA in a template-independent manner.
These processes are required to protect the RNA from nucleases.
Hence mRNA formed in transcription carries genetic code to the small unit of ribosome where the proteins are assembled.
