The ________ duct empties into the vestibule at the level of the second upper molar.
gavmur [86]

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

blagie [28]

Answer:

Because the Arctic glacier is crucial in cooling the land.

Explanation:

The glaciers contained in the Arctic are essential for cooling the earth's climate, which is why Arctic conditions are so important in determining the earth's climate changes.

These glaciers reflect about 80% of the sunlight in the northern hemisphere, and can cool the region's climate. If Arctic glaciers melt, most of the sun's rays will be absorbed by the ocean, increase the temperature and increase the melting of the glaciers.

As a result, the entire ecosystem will be damaged.
