Quick answer: Food enters the human digestive system through the mouth before then moving through the pharynx, esophagus, stomach, intestines, rectum and anus.
To us genetic-engineering and produce a genitivally modified species.
It's the procces of humans giving animal the characteristics they want.
The cilia propel debris-laden mucus away from lower respiratory system structures.
<h3>
What is function of mucous membrane?</h3>
- Another general defense against possible infections is provided by the mucous membranes that line the digestive, urinary, and respiratory tracts, as well as the nose, mouth, and lungs.
- In order to cover and protect the more delicate cell layers underneath it and to trap waste and particle matter, including microorganisms, mucous membranes are made up of a layer of epithelial cells connected by tight junctions.
- Because they feature ciliated appendages, which resemble hairs, the epithelial cells lining the upper portions of the respiratory tract are known as ciliated epithelial cells.
- Mucus that contains debris is forced out and away from the lungs by the cilia's movement. The mucus is then coughed up, sneezed out, or swallowed and destroyed in the stomach. The mucociliary escalator is another name for this route of elimination.

Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
It all depends on the trait. If the dominant is more common that the recessive trait then it is more likely to a dominant trait in the gene pool. But if the recessive trait is more common in the gene pool then you will have a recessive trait. Does this make sense? Let me know if I'm right!
