Answer:

W - Facilitates movement of air by expansion and contraction, X - Traps dust and helps to filter inhaled air, Y - Prevents the wind pipe from collapsing, Z - Help in exchange of gases.

Explanation:

Diaphragm is the muscle that separates the thoracic cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when breathing air in. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body. The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. The trachea connects the larynx to the bronchi and allows air to pass through the neck and into the thorax. The rings of cartilage making up the trachea allow it to remain open to air at all times. Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.

Katen [24]

If one wishes to clone a gene using typical restriction endonucleases, how does the restriction endonuclease identify the appropriate cut sites in the genome using the palindromic sequence.

Restriction endonucleases are a family of enzymes usually found in bacteria that cuts DNA  at a specific sequence called recognition site. There are three type of restriction endonuclease Type I, Type II, and Type III.

Each endonuclease recognizes a particular sequence called palindromic sequence which is a sequence that reads the same sequence in both the strands either reading from the 3 prime end or 5 prime end.

The endonuclease cuts the palindromic sequence in such a way that it produces sticky ends.
