Answer:
D. tip his head back farther to open his airway.
Explanation:
Tilting the head farther back moves the tongue away from the back of the throat, allowing air to enter the lungs.
The answer is a symbiotic relationship.
Symbiosis is an interaction between two different species. Termites live feed on dead plant materials and cellulose. But their body cannot produce enzymes responsible for cellulose degradation. Therefore, they <span>established symbiotic interactions with gut bacteria which are able to digest the fiber in the wood. Gut bacteria break down carbohydrates to the smaller units</span><span>, which are then absorbed and oxidized by the termites</span>
Answer:
An amino acid can be encoded by more than one codon.
Explanation:
Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.
Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
