Answer:
<h2>surface tension from pleural fluid and negative pressure in the pleural cavity</h2>
Explanation:
Each lung enclosed in two membranes called the pleurae . The outer membrane is called parietal pleura , and the inner membrane is called visceral pleura , which closely invest the lungs . A very narrow space exist between two pleura i.e., known as pleural cavity that contains pleural fluid secreted by the pleurae . Pleurae cause the production of pleural fluid and create cavities that seperates organ . Mesothelial cells of both pleural layer secretes fluid and cause lubrication on the surface . These lubrication mimize the friction between pleural layer to prevent the difficulty in breathing and creates surface tension that is responsible for holding the lungs to the thorax wall . Generally , pressure within cavities present between pleural layers is less than atmospheric pressure i.e., negative pressure in the pleural cavity which is also responsible for holding the lungs to the thorax wall .
Umm can you please add a but more context I don’t understand the question your asking
The most likely answer is d
Answer;
No , abiotic factors can not be composed of cells.
Explanation;
An ecosystem is the lowest level of environmental complexity that includes living (biotic factors)and nonliving factors (abiotic factors).
-Abiotic factors are non living factors such as temperature, climate, sunlight, soil quality, etc that are part of an ecosystem.
-Cells are living and therefore they can not be classified as abiotic factors, but instead cells are biotic factors (living factors).
Photosynthesis is a very complex process that occurs when sunlight and oxygen are present.
Good luck
