Diffusion is the process where molecules move from higher to lower concentration areas. It continues until a state of equilibrium is reached, at which the particles continue to move but their distribution remains constant.
In biological terms, diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. This passive movement continues until it reaches a state we refer to as equilibrium. At equilibrium, there is a uniform concentration across the space, and diffusion continues, albeit without any net change, as particles continue to move randomly but their overall distribution remains constant.

B) the internal pressure is less than atmospheric pressure.
C) the internal pressure is greater than atmospheric pressure.
D) the compliance of the lung decreases.
E) the lungs recoil.
Answer:
(B) the internal pressure is less than atmospheric pressure.
Explanation:
The process of respiration is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation). During inspiration, the diaphragm contracts and pulls downward while the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.
Hence, as the thoracic cavity increases in volume the lungs are pulled from all sides to expand, causing a drop in the pressure (a partial vacuum) within the lung itself. As such the internal pressure is less than atmospheric pressure.
During expiration, diaphragm contracts inferiorly and thoracic muscles pull the chest wall outwardly (the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases). As a result, the lungs contract and air is forced out.
During inhalation, air continues to move into the lungs until the internal pressure is the same is atmospheric pressure. Correct option is A.
During inhalation (inspiration), the diaphragm and other respiratory muscles contract, expanding the thoracic cavity. This expansion increases the volume of the lungs, leading to a decrease in the internal pressure within the lungs. As a result, the air from the surrounding atmosphere (which has higher pressure) flows into the lungs, filling them with fresh oxygen. Inhalation continues until the internal pressure in the lungs equals the atmospheric pressure, at which point the flow of air stops, and the lungs are filled with the appropriate amount of air for that particular breath. This process is essential for proper gas exchange, where oxygen is taken into the bloodstream and carbon dioxide is expelled from the body during exhalation (expiration).

It is a product
Explanation:
It is being released from the plant into the air.
Answer: Canyon
A canyon is a deep, narrow valley that exhibits steep sides. The canyon is usually formed on the mountains or plateaus as V shaped valley, when the rocks are weathered by the water of river and erosion by high speed wind current.
Therefore, on the basis of above information Canyon is a feature which is most likely to be formed by flowing water.
basic
alkaline
neutral
Answer:
The answer is D. neutral.
b. hearing
c. precognition
d. telepathy
Answer:
Option b=> hearing.
Explanation:
When information are getting to individual without the person using his or sense organs such as the eyes(vision), ears(audio/hearing), skin(feeling), tongue (tasting) and nose(perceiving smell) then we say that the individual has '' psychic powers'' or the sixth sense.
extrasensory power.
If you look at the meaning of option (a), that is clairvoyance, it is more of seeing the future which can never be seen with our normal eyes, therefore, it is an extrasensory power
Option (b), can be done with our normal ears, hence, it is not an extrasensory power.
Option (c) and (d) that is precognition(knowing what is coming without seeing with norm human eyes) and telepathy(being able to read People's mind) respectively are both extrasensory powers.
