1-G, 2-D, 3-B, 4-F, 5-C, 6-A, 7-E
The answer is C. You don't really need the others because they don't impact your physical health. If you think about it that way!!
Answer:
<em>His decreased residual volume and decreased lung compliance contribute to his altered ventilation.
</em>
Explanation:
Pneumoconioses are distinguished by reduced residual volume and impaired compliance with the lungs.
Pneumoconiosis involves asbestosis, silicosis, and the pneumoconiosis (CWP) of coal workers.
The most prevalent mineral dusts proven to cause pneumoconiosis in the workplace are asbestos, silica (rock and sand dust), and coal dust.
Cough and shortness of breath are by far the most common symptoms of pneumoconiosis. The threat is usually greater when people are exposed to high levels and/or long periods of time from mineral dusts.
One risk factor is the insufficient or inconsistent usage of personal protective equipment (PPE) such as respirators (specially designed breathing masks), as avoiding inhalation of dusts would also avoid pneumoconiosis.
Answer:
The unknown radioactive element is present in pitchblende.
Explanation:
Marie Curie was the scientists that mainly worked on the radioactive element. She was the first scientist who won the noble prize in two different fields of science.
The pitchblende was the mineral sample that was noticed by Marie curie during her experiment. Pitchblende contains a more radioactive element that uranium and confirms that she had found a new element.The new element was polonium with hundred times more radioactive than uranium.
Thus, the answer is unknown radioactive element is present in pitchblende.
