Answer:
The presence of air in the pleural cavity
Explanation:
A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.
Answer:
Luminosity is an intrinsic(natural) measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing(decrease) flux of light as a result of distance according to the inverse-square law.
Answer:
Explanation:
I think the first one is correct.
The second one is half right (conduction works mostly in solids). The second part is not correct. Convection works mostly in gases.
The third one is wrong about waves. Conduction usually has direct contact of particles.
The last one is not correct. There is no visible movement of matter in conduction. The definition for convection is also incorrect.
Answer:
A. The same species of organisms from one geographic area make up a population.
Explanation:
- Population refers to a group of organisms of the same species living in the same geographical area at the same time. Therefore organisms of similar species make up a population.
- Several populations in turn make up a community. This explains why a community refers to groups of different species living in the same geographical area or an ecosystem.
Are you asking for the definitions?
