Answer:
Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.
Explanation:
Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.
Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.
B, they are important because they help produce ATP.
Answer:
The difference between C3, C4, and CAM photosynthesis is the way plants extract carbon dioxide from sunlight. This depends largely on the plant's habitat. C3 photosynthesis produces three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
CAM plants open their stomata at night, C3, and C4 open during the day.
