7. Which of the following is an anaerobic activity? a. Glycolysis
b. Photosynthesis
c. Kreb's Cycle
d. All of the above

a. glycolysis

Explanation:

I'm really unsure about this but in glycolysis if there is no oxygen, there is a process called fermentation. Fermentation is an anaerobic process and is used when our body lacks in oxygen

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
