Answer:
uaa
Explanation:
An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.
Answer:
I'm pretty sure it is B, because of natural selection
Gizzard
Birds such as chicken, doves and others, and earthworms have gizzard which are responsible for storing and softening the consumed food in their digestive tract. The gizzard serves as the grinder of these food in preparation of the absorptive phase of the G.I tract.
Answer: The Parietal lobe

Answer:
The cilia in the upper respiratory tract move mucus down toward the pharynx whereas the cilia in the lower respiratory tract move them up toward the pharynx.
Explanation:
Through the internal nares, the air enters nasopharynx from the nasal cavity. This air has dust-laden mucus. The nasopharynx is lined with ciliated pseudostratified columnar epithelium. These cilia move the mucus down toward the most inferior part of the pharynx. The lining of the larynx inferior to the vocal folds is made up of ciliated pseudostratified columnar epithelium and have ciliated columnar cells, goblet cells, and basal cells.
The goblet cells serve to produce and secrete mucus. The mucus from goblet cells helps trap dust that was not removed in the upper passages. Therefore, the cilia in the upper respiratory tract move mucus and trapped particles down toward the pharynx whereas the cilia in the lower respiratory tract move them up toward the pharynx.
