Which of the following scenarios best explains the concept of the tragedy of the commons? A Fish farming, a type of aquaculture, produces fish through selective breeding to produce a cheap source of protein, reducing the fishing pressure on wild stock fish
B
A collapse of the fishing industry leads to a loss of fishing-related jobs, which will have negative consequences on the economy.
Declines in the fish population lead to a decline in the population of fish predators, affecting the entire food chain.
Fish are shared resources, and as the fishing industry competes for the fish, the resource extraction is no longer sustainable

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

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."
