Which is the best explanation for how air masses move across the United States
Akimi4 [234]
Warm air rises, expands, then cools. As cool air sinks it may cause precipitation. Some air masses such as the MT which originate in warm environments carry humid air and cause heavy precipitation in some areas.

What is bacteria flagellum? What is made of and its function? What type of organization can flagella have on cells?
Nadusha1986 [10]

Answer:

Bacterial flagella is the external structure that is thin, long and filamentous. It is attached to the cell wall of the bacteria which helps in the locomotion of the bacteria. It has three parts a filament, hook and basal body. The basal body is incorporated in the cell membrane.

A flagellum is made up of a protein called flagellin. It is a rigid protein and helps in making the hollow core of the filament by assembling together to form a structure which is cylindrical in shape.

The organization of flagella on bacterial cells is helpful in the identification of bacterial species. Mostly 4 type of organization of flagella is present on bacterial cell that are monotrichous, amphitrichous, lophoyrichous and perithrichous.

In monotrichious bacteria, only one flagella is present on one side, in amphitrichous both side of the cell have an equal amount of flagella. Lophotrichous bacteria have a group of flagella at one side of the cell and amphitrichous bacteria have many flagella distributed equally on its cell.

_________ is a smooth muscle cell has a central nucleus but lacks striations.
Natalija [7]

Answer:

Linings of hollow organs

Explanation:

Smooth muscle cells are usually found in the lining of hollow organs such as all arteries and veins, wall of stomach, uterus, urinary bladder, digestive system etc. The cells of these linings are spindle shaped and consist of a nucleus at the center which lacks striations.  

They work as a housekeeper and are under involuntary control except the heart. They lack striation because of irregular arraying of actin and myosin filament along the length of the cell.
