I can tell you that angle measure of X is 34 degrees. This is because angle x is vertical to the angle on the other side, and on the other side it the angle that measures 34 degrees.
I can't tell you what angle y is because it's been awhile since I done math problems like this.
Answer:
C. sea-floor spreading at a divergent boundary
Explanation:
"A" and "D" is incorrect because the action is the seafloor, not the mountain
"B" is incorrect because the passage states the seafloor is pulling apart not pushing in

Hope this helps!
Answer:
New GPP
kcal/m2
Explanation:
Given -
Number of new trees planted 
Before planting new trees, the gross annual primary productivity of a particular wetland ecosystem
kcal/m2
The increase in gross primary productivity
%
The new GPP will be equal to
Existing GPP +
% of Existing GPP
Substituting the given values, we get -

New GPP
kcal/m2
Photorespiration is when plants take in oxygen and light and release carbon dioxide. Contrary to photosynthesis. C3 plants have no system to minimize photorespiration, C4 plants minimize photoresperiation by separating the initial CO2 fixations and the Calvin cycle to be performed in different types of cells. CAM plants minimize photorespiration by taking CO2 by opening their stomata at night and then keeping the stomata closed during the day while they do photosynthesis.
