Anton [14]

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.

in a series of experiments Griffith infected mi've with oa nonvirulent r strain bacteria and highly virulent s strain bacteria.

Andrej [43]

Answer:

This demonstrate the transforming principle.

Explanation:

Griffith performed the experiment on the virulent bacteria and non- virulent bacteria. The non- virulent bacteria produce rough colonies and did not cause pneumonia. The virulent bacteria produces smooth colonies that kill the mice and caused pneumonia.

When Griffith mixed the on virulent bacteria and heat killed virulent bacteria he found that the mice were killed. He concluded that there was transforming principle that turns the non- virulent bacteria into virulent bacteria from the heat killed bacteria. Something, has been transferred from the heat killed bacteria to the non- virulent bacteria. Later, he found that dead mice blood sample contained both the non-virulent rough bacteria strains and virulent smooth strains of bacteria.
