Answer:
The correct answer is "Fist sequence; Fourth sequence; Second sequence; Third sequence".
Explanation:
Inversion of DNA is a process that often occurs during evolution of chromosomes. It occurs when the breakage of a chromosome in two places, results in the reinsertion of a DNA but in a reversed fashion. The evolutionary order of predecessors of inversion of DNA can be established by looking on the number of nucleotides that are different in the sequences of DNA. In this case, the first sequence is the ancestor and it haves the sequence "ABCDEF". The second in the evolutionary order is the fourth sequence since it originates from the first sequence only by changing the "BC" nucleotides to the end of the sequence "ADEFBC". The third in the evolutionary order is the second sequence since it still starts in AB, but has the other four nucleotides different: "ABFEDC". The last in the evolutionary order is the third sequence, which is completely different and reversed respect to the first sequence: "FEDABC".

Glad to help :) brainliest
During an experiment the factors we observe are
1) what reactions are taking place(if any)
2) is there a change in the colour of the substances used
and so on. Observation totally depends on the experiment
the things we measure are weight, mass, time, temperature,etc.
hope it helps u
