Drag each label to the correct location on the image.

identify the elevation and the percentage of oxygen available at each elevation.

8,850 m
57%
33%
4,500 m
100%

The correct matches are:

1. Sea level (0 m) - 100%

2. Mid-level elevation (4,500 m) - 57%

3. Peak (8,850 m) - 33%

The level of oxygen in the atmosphere depends a lot on the elevation. The smaller the elevation, the higher the oxygen level, and vice versa, the higher the elevation, the lower the oxygen level. So we have a situation in which the oxygen level is the highest at 0 elevation, or rather at sea level. As we go to higher elevations, let say to around 4,500 m, the oxygen level is significantly dropped, which makes it difficult for breathing. If we go even on higher elevation, like 8,850 m, than the oxygen level will much lower, and a human will need to undergo intense long training and also carry oxygen with him/her in order to survive.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
