The change in partial pressure from the alveoli (high concentration) to the capillaries (low concentration) drives the oxygen into the tissue and the carbon dioxide into the blood (high concentration) from the tissues (low concentration), which is then returned to the lungs and exhaled.
Once in the blood of the capillaries, the O2 binds to the hemoglobin in red blood cells which carry it to the tissues where it dissociates to enter the cells of the tissues.
The lungs never fully deflate, so air that is inhaled mixes with the residual air left from the previous respiration, resulting in a lower partial pressure of oxygen within the alveoli.

¿Como realiza la respiración las levaduras y que resultado se obtiene?​
natita [175]

Answer:

Cuando la levadura activa (viva) tiene tanto azúcar como oxígeno disponibles, "respira" mediante un proceso llamado respiración aeróbica. En esta reacción, las células de levadura utilizan glucosa (azúcar) y oxígeno (del aire) para producir energía. También producen agua y dióxido de carbono (un gas). Este es el mismo proceso químico utilizado por los humanos.

jasenka [17]

Answer:

D) Folded mountain with jagged, rough edges

Explanation:

The incident which happened some fifty million years ago was the collision of the Indian plates and the Eurasian plates thus giving rise to the folded mountains that are characteristic of the Himalayas. Subduction was not possible when these two plates collided because they had the same density.

So, the force with which the two plates collided resulted in the formation of folded mountains that rose upward. The peaks of these mountains were jagged, rough, and uneven.
