A substance that can be used or prepared for use as food
Answer:
True
Explanation:
Methanogens are prokaryotic microbes that produce methane as a by-product of metabolism in anoxic or anaerobic conditions. They are commonly found in the gastro-intestinal parts of ruminants, Marine sediments, and wetlands etc. They are responsible for the methane content released when cows burp/belch and the marsh gas of the wetlands.
Methanogens are strictly anaerobic (they thrive best in a no-oxygen condition) and play a vital ecological role by using up excess hydrogen as an energy source and other products of fermentation released during anaerobic respiration. Due to this, methanogens thrive in an environment which has all electron acceptors e.g. Oxygen, Sulphate, Nitrate etc. removed. This excludes CO2 because methanogens use CO2 as their carbon source.
Found in the depths of the ocean.
The genetic code defines how codons, sequences of nucleotide triplets, specify which amino acid will be added next during process of translation (protein synthesis).
The genetic code is universal among organisms. That means that the same codons code for the same amino acids in different organisms.
It is known which amino acids are coded by which codons. If we know sequences of amino acids, we then also know sequences of nucleotides in DNA/RNA. If we know DNA/RNA sequences we can then reveal relationships among different organism by compering similarities in those sequences.
