Answer:
Let's say for an example, someone was having a day and they where making escuses and what not, instead tell them positive things or share your stuff with them. You always can positive in horrible situations. Sorry if this doesn't make sense.
Explanation:
lateral projection of the elbow, the arm should be flexed 90 degree .
The lateral view is an additional view obtained at virtually every diagnostic evaluation. A lateral view may be obtained as a mediolateral view (ML) or lateromedial view (LM) view depending on where the imaging tube and detector are located.
Position of part The elbow joint should be flexed 90 degrees and positioned laterally in a lateral view radiograph. A lateral radiograph of the elbow requires the elbow to be flexed 90 degrees with the forearm and humerus laying flat on the table . Lateral view is important because It clearly displays these areas and is especially useful in detecting lower-lobe lung disease, pleural effusions, and anterior mediastinal masses.

Answer:
1. Ends of the respiratory branches are called alveoli.
2. C. To control blood flow to different areas of the body depending on activities
Explanation:
1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.
The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.
2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.
This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.
Answer:
C. A phosphate group from ATP is added to a transport protein, changing its shape and facilitating transport.
Explanation:
ATP hydrolysis drives the active transport of substances through membrane proteins. During the process, the released phosphate group from ATP is added to the nucleotide-binding site present on the membrane protein to trigger a conformational change in it.
For example, the binding of a phosphate group from ATP to the nucleotide-binding site of NA-K+ ATPase brings about a conformational change in the protein. The phosphorylates pump has more affinity for K+ and lower affinity for Na+. It facilitates the release of bound Na+ from one side of the membrane to another.
