Answer: Southern blot
Explanation:
The techniques of Southern blotting helps to identify specific sequences of DNA among two or more samples that have been collected from organisms to be investigated.
This biochemical process also involves electrophoresis and hybridization of DNA to obtain the right order of the nucleotide bases, as similar order of bases would infer COMMON ANCESTRY between the two organisms.

c
Explanation:
An experiment in which an observer tests a hypothesis by looking for changes brought on by alterations to a variable. In a controlled experiment, an independent variable is the only factor that is allowed to be adjusted, with the dependent variable as the factor that the independent variable will affect.
in Basic terms The control group provides a baseline that lets us see if the treatment has an effect.
The answer is: Ecological Succession
STEPS:
1.) Bare rock (there is no grass at this point).
2.) Lichens (lichens begin to appear).
3.) Small Plants & Lichens (small plants begin to grow & the lichens are spreading).
4.) Grasses (grass starts to grow in certain spots).
5.) Shrubs & Grasses (the grass has covered, at least the majority, of the ground and shrubs begin to appear).
6.) Trees (the shrubs have grown into trees that are tall enough to provide shade)
7.) Animals (the animals return or new animals appear).
