D: Cellular respiration
Explanation:
Because we work in a sea of oxygen (air is 20.9% oxygen) it is difficult to measure the small changes in oxygen concentration that occured during respiration. The rate of Cellular Respiration can be measured in the dark by determining the amount of oxygen gas consumed in a period of time.
Hope this helps you out!
Answer:
2y=8-x
y-2x=-1
y-2x=-1
y = 2x-1
Substitute for y in the 1st
2(2x-1)=8-x
4x-2=8-x
5x = 10
x = 2
y=2x-1
y = 3
Explanation:
2y=8-x
y-2x=-1
------------
Rearrange:
x = 8-2y
y = 2x-1
------------
Substitute to get:
y = 2(8-2y)-1
y = 16-4y-1
5y = 15
y = 3
-------------------
Substitute to solve for "x":
x = 8-2(3)
x = 2
