g When an oxygen molecule diffuses from the air in the lung into the plasma in a capillary in the lung, how many times does it h

Biology

serg [7]3 years ago
8 0

Answer:

The answer is 2.

Explanation:

When oxygen gets into the lungs, it first needs to diffuse through the alveoli and into the blood. Then through the veins and capillaries, it diffuses into all the calls in the body. It does so quite easily because it is a nonpolar and a very small molecule with a low concentration inside the cell. This gives it the ability to diffuse easily through the cell membrane.

So the number of times that oxygen has to diffuse through a plasma membrane is two.

I hope this answer helps.

Mumz [18]

Answer:

The trait is Y-linked

Explanation:

The only plausible explanation behind the inheritance pattern shown by the porcupine trait is that it is <u>Y-linked</u>.

<em><u>Y-linked traits are limited to the Y chromosome only</u></em><em>, a sex chromosome that is peculiar to only the male gender. Chromosomally, females are XX while males are XY. Hence, only the male gender has the genetic capacity to inherit the porcupine trait. This is why only the sons of Edward Lambert, and never the daughters, exhibited the trait. </em>

Answer:

Option (1).

Explanation:

Saturated fatty acid may be defined as the fatty acid with the single bonds between the carbon atoms. The unsaturated fatty acid consist of double and triple bond in its structure.

The melting points differs between the saturated and unsaturated fatty acid. The saturated and unsaturated fatty acids have high difference in their melting point and this difference may changes as the double and triple bonds are increased or decreased in the fatty acid structure.
