So, as a result of warming in the Sea of ​​Japan, spawning navaga shifted to an earlier date, because of the reduction of the area of ​​"cold spots" in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab are lengthened, but because of the temperature rise to the east of Japan, spawning saury expanding. These changes significantly affect the success of reproduction, resulting in changes populations of their fishery.

erastovalidia [21]

Answer:

Transosteal

Explanation:

One of the ways to get  a missing or broken tooth fixed is through dental implants. It can also be used to fix loose teeth. For this to occur, a tooth root is needed to hold in place the dental prosthesis. Dental implants involve surgically fixing of metal frames (surgical component) into the jawbone beneath the gum to serve as the tooth root. This surgical implant, which now serves as a tooth root, enables the dentist to fix a replacement tooth.

<em>Transosteal implant</em> is a type of dental implant in which the surgical component is a U-shaped metal frame or pins that is inserted into the lower jaw followed by the replacement tooth on top during tooth replacement.

What function do the alveolar sacs serve in the respiratory system?
Brrunno [24]

These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.

In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.


SHORT ANSWER:

Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
