<span>A treatment for p</span>neumothorax and pleural effusion may include inserting a needle or tube into the chest cavity.

Inserting chest tube as a treatment for pleural effusion is due to the accumulation of fluid( like blood or lymphatic fluid) in the pleural space.
Answer:
Option A
Explanation:
The concentration of salt is lesser than the concentration of salts in the solution. The membrane of the cell is permeable and hence it shall allow movement of salt ions towards the region of lower concentration from the region of higher concentration in lieu to the concentration gradient formed (supported by differences in concentration of salt within and outside the cell). Like the movement of salt, the water shall also move from region of high concentration to region of low concentration and thus water will move out of the cell thereby shrinking it.
Hence, option A is correct
Darwin’s theory suggests that there is some evolutionary advantage towards beetles because they can use camouflage as a defense strategy against predators.
hello!
Volcanoes often form in the areas where tectonic plates make contact. The friction created between two plates by the constant movement melts the Earth's crust, causing the rock underneath the crust to turn into magma due to the great temperatures created by friction.
have a goed day
Answer:
no
Explanation:
cells maintain internal environmental equilibrium by the process osmosis.
when the cell is moves into a hypotonic solution, water molecules move into the cell by osmosis, hence creates excess water in the cell. In order to maintain water equilibrium, reverse osmosis occurs to move the water molecules out of the cell.
On the other hand when the cell is placed in a hypertonic solution, water molecules move from the cell to the outside environment, causing insufficient water in the cell, but to correct this, the cell again initiates reverse osmosis to bring water back into the cell.
Note: There is nothing like the cell moving from one solution to another to attain an internal environmental equilibrium.
