<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>
Answer:
The correct choice would be: "The data supports the hypothesis because when annual temperature deviations are below normal, the annual number of hurricanes increases."
Explanation:
The large discrepancies between temperatures due to global warming promote the appearance of hurcanaes, that is, the greenhouse effect and pollution encourage the appearance of excessive thermal amplitude and this helps the appearance of hurricanes.
Answer: C Biodiversity has prevented this ecosystem from being sustainable.
Explanation:
The extensive grazing by the organisms in the Chihuahuan Desert which has made the ecosystem unstable has made the ecosystem incapable of sustaining the organisms that depend on it.
This is because the extensive grazing means that the ecosystem in the desert which comprises of the flora has seen its resources being overused and can now no longer support the organisms in it.
Answer:
B) Additional studies will be the reliability check for the claims.
