The parotid duct empties into the vestibule at the level of the second upper molar.
Around the back of your lower jaw is where the parotid gland is located. Saliva then passes via a tube known as the parotid duct. The duct's opening is where the saliva spills into your mouth. Different factors might cause the parotid duct to become clogged. The region may swell up as a result of this.
Each gland's front faces a lengthy excretory channel called the parotid duct, which emerges just beneath the masseter muscle. The duct enters the mouth by the buccinator muscle and opens on the inner cheek surface, typically next to the maxillary second tooth

<u>Answer:</u>
- few nutrients
- high pressure
- low temperatures
<u>Explanation:</u>
1. Few nutrients: open-ocean zone is located way far from the land, which is the main source of the essential nutrients.
2. High pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.
3. Ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface.
4. Varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.
5. Low temperatures: the temperature of open-ocean zone ranges from a low of -2°C to an average of 17°C.
Bb × bb = 2 Bb : 2 bb = 1 Bb : 1 bb
Thus, the phenotypic ratio would be 1 Dominant Phenotype : 1 Recessive Phenotype.
