How could a building be protected against a sinkhole? Are there physical / construction solutions that could mitigate (lessen) the damage done by a sinkhole?

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."

enzyme speed up the reactions

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

mass and weight are closely related because mass affects the weight of an object experiencing the effects of gravity. weight is the measure of the force of gravity on an objects's mass, while mass is the measure of how much matter there is in an object.
