<h3><u>Answer;</u></h3>

756 mm Hg

<h3><u>Explanation;</u></h3>
  • Intrapleural pressure is the pressure of the air within the pleural cavity, between the visceral and parietal pleurae. This pressure changes during different phases of breathing.
  • <em><u>Due to certain characteristics of the lungs, the intrapleural pressure is always lower than, or negative to, the intra-alveolar pressure. It  remains approximately –4 mm Hg throughout the breathing cycle.</u></em>
  • <em><u>Therefore; if the intrapulmonary pressure was 760 mm hg then the intrapleural pressure will be (760 -4) mm Hg, that is 756 mm Hg</u></em>

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children
vova2212 [387]

Answer:

He should request type O on his dating survey.

Opine's blood type must be AO to have a higher probability of producing O offsprings.

Explanation:

O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.

O blood type results are possible thanks to OO genotypes.

If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.

As regards the mother, her blood type should be OO.

We can see this more clearly in Punnet Square.

<u> ║ A ║O</u>

<u>O║AO║OO</u>

<u>O║AO║OO</u>  

There is a 50% of probability of having O offsprings with AO and OO.

  <u>║ A ║A</u>

<u>O║AO║AO</u>

<u>O║AO║AO </u>

With AA and OO, the probability is 0%

 <u>║ A ║O</u>

<u>A║AA║AO</u>

<u>O║AO║OO</u>

With both parents having AO, blood the probability of having a OO offspring is 25%.

In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.
