The anterior portions of the nasal cavities just inside the nostrils are known as the Vestibules
<h3>
What are nasal vestibules? </h3>
- The nasal vestibule is the area just inside the nostril (nose opening) that leads into the nasal cavity.
- The nasal vestibule contains cartilage of the nose and is lined with tissue that contains small, course hair. These hairs help filter dust, sand, and other particles to stay them from entering the lungs.
- The vestibule of the traditional adult nose is a specialized organ with very characteristic structures and specific functions and is the beginning of each nasal passage. Here the tract makes its first contact with the outside world of air.
- The vestibule is surrounded almost entirely by its half the nasal lobule, bounded laterally by the ala, or wing, medially by the mobile septum and columella, superiorly by the cul-de-sac and limen vestibuli, and posteriorly by the skin lying on the alveolar ridge of the superior maxilla

B , bacteria is a complete organism
Answer:
d. Pancreas
Explanation:
The digestive system structure which releases sodium bicarbonate into the small intestine, resulting in a change in the pH of chyme from acidic to basic is called the pancreas. It makes use of the pancreatic duct in releasing the bicarbonates into the small intestine.
The bicarbonates aids the digestive processes and also neutralizes the duodenum from acidity. This is due to the the acidic food from the stomach and is as a result of the stomach being acidic and having acids such as dil. Hcl.
Answer:
Phylogenetic relationships
1. includes all descendants from a single common ancestor >>> monophyletic group
2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group
3. includes some but not all descendants from a single common ancestor >>> paraphyletic group
Explanation:
A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).
