The ____________ in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is ____________ . This caus
Oxana [17]

Answer:

The <u>PCO₂</u> -carbon dioxide partial pressure- in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is <u>45 mmHg</u>. This causes <u>carbon dioxide</u> to diffuse down its partial pressure gradient from the blood into the alveoli.

Explanation:

Gas exchange is a physiological process that involves the entry of oxygen into the body and tissues and the exit of carbon dioxide, a product of metabolic reactions.

At the pulmonary level, gas exchange occurs between the alveoli and the alveolar capillary, and the diffusion of gases across the alveolar-capillary barrier is dependent on a pressure gradient due to the partial pressure of gases.

In the case of CO₂ the diffusion goes from where the partial pressure is higher to where it is lower, i.e. <u>from the alveolar capillary, where the PCO₂ is 45 mmHg, to the pulmonary alveolus, where the PCO₂ is 40 mmHg</u>.

Lateral gene transfer between individuals of a species is called
adelina 88 [10]

Answer:

Horizontal gene transfer.

Explanation:

Horizontal gene transfer happens when an organism acquires a gene that benefits its development. This individual then can transfer this information to another cell without it being its breed or duplicate. Normal gene transfer happens "vertically" from a parent to a daughter cell, but in this case, duplication is not needed for another organism to acquire the gene.
