The figure above shows two different systems. Each system contains a flask holding an unknown liquid at room temperature. Their masses are recorded on a digital balance at 0, 1, 2, 3, 4, & 5 minutes. The corresponding masses are recording in the data table above. Which uncontrolled variable most likely explains the reduction in mass in System 1?

A) the liquid is evaporating
B) digital balance error in system 1
C) the liquid is dissolving inside the flask
D) water is condensing on the outside of the flask

idk lol use google m8

layer 3 is younger than layer 6.

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.'

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
