Environmental stresses at high altitudes include
a. increased temperatures.
b. lower humidity.
c. decreased uv radiation.
d. quick ascent.

the answer is B. lower humidity  because People have the misconception that a high humidity means it is hot, sultry and muggy. However, mostly the opposite is the case. As temperatures fall the relative humidity normally rises because the amount of water vapor in the air is mostly reasonably constant and air at lower temperatures holds less water vapor.

hope this !

feel free to mark as brainliest: )

2. the percent of fat would be the percent of fat from the serving size, added up to the entire bag of calories

3/4. the saturated fat would be on the bag label, but im pretty sure if you take the serving size and do the math to figure it out you could find out in total the fiber, saturated fat,etc..

5. no probably not
