Amy is experimenting to see how a truss (a type of support) can strengthen a bridge. Amy builds several models of bridges out of toothpicks. Each model has a different number of trusses.

Amy suspends each model between two desks. She then adds lead weights to each bridge, one-by-one, until the bridge breaks. In the chart below, Amy recorded how many lead weights each bridge held before breaking.
What is a valid conclusion that Amy can draw from her experiment?

it will increase due to the time span

request for reexamination

sorry, is there a picture? i do not see any arrows.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
