exchange of gases in the human breathing system takes place in the?​

Answers

Answer 1
Answer

alveoli

Explanation

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Answer 2
Required Answer :-

The exchange of gases takes place in the alveoli.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Additional information :-

Alveoli are microscopic air sacs.

They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.

Shown below are 4 stages (A,B,C,D) (not in sequence) of a certain kind of cell division.

Answers

The diagram below shows a cell undergoing mitosis (cell division). The correct order of the stages is B, C, D and A.

Mitosis is a type of cell division in which a parental cell divides to produce two genetically identical daughter cells.

In this case, an animal cell is undergone mitosis because the cell exhibits centrioles (only found in animal cells) and lacks cell walls (only present in plant cells).

The stages of mitosis include prophase, prometaphase, metaphase, anaphase, and telophase.

Answers

Answer:

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

Explanation:

Involves one cell division?

Results in two daughter cells

Results in diploid? daughter cells? (chromosome? number remains the same as parent cell)

Daughter cells are genetically identical
