Answer:
19.32 m²
Explanation:
The area of a living room is the product of its length and breadth. The area is given by:
Area = length × breadth
1 meter = 3.28 feet. Hence:
Length = 16 ft
16 ft = 
Breadth = 13 ft
13 ft = 
Area = length × breadth = 4.88 m × 3.96 m = 19.32 m²
Hence 19.32 m² of carpet is needed for the living room

Answer:
The correct answer is osmosis is the movement of water across the membrane;diffusion is the movement of molecules from a higher to lower concentration with or without the presence of membrane.
Explanation:
Diffusion and osmosis are the two most important process of passive transport.Both diffusion and osmosis helps in the movement of water molecules from high water concentration region to region of low water concentration until equilibrium in both sides is reached.
Osmosis needs the presence of a semipermeable membrane to occur.
Most of anti-anxiety agents work by depressing the central nervous
system activity. They
produce a calming effect by potentiating the effects of gamma-aminobutyric acid
(GABA), one of the inhibitory neurotransmitters and thereby reduces the
transmission of nerve impulses. In addition, they act particularly on the
limbic system and the reticular activating system.

Jellies
Salt cured meats
Honey
High osmotic pressure can be used as a natural preservative. In high osmotic pressure, the microbes will hardly survive as their surrounding concentration is too high and induce severe osmosis. The osmosis will take the microbes water, makes it shrink continually lead to the microbes death.
In those 3 foods, there is a high concentration of sugar or salt that increase the osmotic pressure.</span>
