Answer:
B: The shorter and more rounded the Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains
Explanation:
- The Appalachian mountains form a system of mountains in eastern North America and are older than rocky mountains as they were formed 480 million years ago and are similar to those of the alps. They form a barrier to the east to the west.
- They extend to southeast Canada and form zones of 300 miles wide. They form the mountain ranges surrounding hills and the dissected plateaus forming at an elevation of 6,684 meters from the sea level. <u>Whereas the rocky mountains are younger and have an elevation of 4,401 meters.</u>
The first is D and the second is B

<h3><u>Answer;</u></h3>
In order from the most likely to bind an oxygen to least likely;
3 bound o2, po2=100mmhg1 bound o2, po2=100mmhg3 bound o2, po2=40mmhg1 bound o2, po2=40mmhg
<h3><u>Explanation;</u></h3>
- Haemoglobin is more likely to bind oxygen if its other oxygen binding sites have already bound to an oxygen molecule.
- The higher the partial pressure of oxygen in the blood also makes it more likely that the hemoglobin will bind oxygen.
