Answer:
He can deduce that The pO2 of her cells is less than or equal to 200 mmHg.
Explanation:
Partial pressure of oxygen(pO2) measures the amount of gaseous oxygen dissolved in the blood. It purposes to measure the effectiveness of the lungs in pulling oxygen from the atmosphere to the lungs.
In the incubator where the gases levels are carefully regulated, a pO2 of 200mmHg on the incubator deduces that the pO2 of her cells is equal or less than 200mmHg.
Answer:
D. a wide variety of gradual and sudden changes to ecosystems
Explanation:
There have been different global climatic changes throughout the history of planet earth. The changes have been gradual or abrupt and have been due to various causes, such as those related to changes in orbital parameters, precession , variations in solar radiation, continental drift, periods of intense volcanism, meteorite impacts etc. Some changes to the ecosystems related to climatic changes are, for example,The Cretaceous-Tertiary extinction (which probably caused the extinction of the dinosaurs), the contraction of the forests during the last glacial maximum promoting biological diversification, the melting of the polar caps increasing sea level etc.
