Answer:
95%.
Explanation:
Oxygen-hemoglobin dissociation curve:
Oxygen-hemoglobin dissociation curve is basically a sigmoid curve which relates between the saturation of oxygen (SO2) and partial pressure of oxygen in blood (PO2). It shows the affinity of oxygen with hemoglobin at different temperature and other factors. In the oxygen-hemoglobin dissociation curve; saturated oxygen is ploted on verticle axis and partial pressure of oxygen in mmHg on the horizontal axis.
Here in the above scenario at the high altitude oxygen is less and at 80 mmHg, Hb would be 95% saturated.
By definition, a keystone predator is a predator that once it is eliminated from the food web, prey population thrives. This often leads to a decline in diversity within the food web. With this in mind, we can say that A and B are wrong. Additionally, from the information, we can say that D is the correct answer since they do play a very important role in the food web.
The correct answer is (a.) a mutation of the hemoglobin allowing better oxygen-carrying capacity. The mutation of the hemoglobin that allows a better oxygen-carrying capacity would be the most beneficial to an elephant and its descendants.
Answer:
The chromosomes are in the nucleus. :)
I could answer this but what are your answer choices??
