Tachycardia, decreased or absent breath sounds on the affected side, hyperresonance, and sudden chest pain on the affected side are clinical manifestations of: A) Sarcoidosis
B) Pneumothorax
C) Hypersensitivity pneumonitis
D) adult respiratory distress syndrome

Option B.

Pneumothorax

Explanation:

Pneumothorax occurs when air buildup between the chest wall and the lungs thereby leading to increased pressure in the chest and it inturn decrease the amount of blood that flow back to the heart because the blood find it difficult to force it's way into the chest and the heart. This is cause by injury to the chest, lung danage, rupture air blisters and mechanical ventilation.

The symptoms include decreased or absent breath sounds on the affected side, hyperresonance, and sudden chest pain on the affected side , racing heart, shock.

When a pneumothorax is large, a needle or tube is used to remove excess air.

a covalent bond, specfically triple bond

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
