Answer:
70% solution is more effective
Explanation:
The 70% solution is more effective at inhibiting microbial growth than the 100% solution of the ethyl alcohol.
This is because the pure ethyl alcohol coagulates the protein that is in contact with it.
Also, pure alcohol will tend to evaporate faster than the 70% solution of the ethyl alcohol and it will not be that much effective.
The correct answer is: marsupials.

This provided the first substantial evidence for the endosymbiosis hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.
Explanation:
<em>What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.</em>
