Why is some amount of air is left inside in your lungs after inhalation

Answers

Answer 1

Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.

So your answer will be Residual volume...

Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D

Answer 2

It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.

Answer:

When the water availability of a plant's environment decreases, the plant can respond by closing its stomata. This reduces the amount of water that the plant loses through its leaves due to transpiration. Closing the stomata also reduces the amount of carbon dioxide that the plant can take in through its leaves, which will most likely result in A. a decreased rate of photosynthesis. B. no change in the cellular processes of the plant. C. an increased rate of photosynthesis. D. an increased rate of cellular respiration.

Answers

Answer:

A. a decreased rate of photosynthesis.

Explanation:

Stomata is a structure in the leaves of higher plants, which they use majorly for the purpose of gas exchange. However, the process whereby plant loses water called transpiration also occurs via the stomata. In a situation whereby the availability of water in a plant's environment is low, the plant responds by closing its stomata in order to conserve water (reduce the amount of water that the plant loses through its leaves due to transpiration).

Closing the stomata by plants means not allowing ample carbon dioxide (CO2), which is needed for the process of photosynthesis to occur, to enter the plant. This will most likely result in a DECREASED RATE OF PHOTOSYNTHESIS.

3) .... is the process that bacteria use to cause the decay of death organisms ​

Answers

Answer:Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Given the diagram below, which of the following ordered pairs represents the
vertex, A?

O A. (b cosc, b sinC)
O B. (b cos C, c sinc)
O C. (a cosB, a sinB)
O D. (a cosc, b sinC)

Answers

Answer:c

Explanation:because cosin of b is c

(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.

What is Vertex ?

In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.

The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.

In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.

Hence option D is correct.

Answers

duplicating the dna

Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).

The cell cycle is divided into the interphase and the mitotic (M) phase.

The interphase of the cell cycle is in turn divided into three different phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.

During the S phase, the chromosomes (i.e., the genetic material) of a cell are duplicated.

Mitosis is a type of cell division that follows the interphase of the cell cycle by which a somatic (body) cell divides to produce two genetically identical daughter cells.

In conclusion, Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).

7. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise

8.Convection currents in the mantle drive plate tectonics. Convection is the reason for ocean currents. Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.

Both the mantle and ocean experience the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.
