Answer:
A homogeneous mixture is a mixture that has been mixed together so well that the different parts will not settle out on their own.
Explanation:
The great peril happened in on October 8, 1871 and burned through the heart of Chicago.
- The fire burnt for more than 24 hours, killed more than 300 people and destroyed more than 17,500 buildings.
- The aftermath of the accident left four square miles of Windy City including its business district in total ruins.
- The mayor of Chicago who was "Roswell B. Mason" lived in Chicago at the time of the fire in 1871

<span>ART BY THOMAS POROSTOCKY</span>PRO: RESEARCH ON GENE EDITING IN HUMANS MUST CONTINUE
By John Harris
<span>John Harris is professor emeritus in science ethics at University of Manchester, U.K., and the author of How to be Good, Oxford University Press 2016.</span>
In February of this year, the Human Fertilization and Embryology Authority in the United Kingdom approved a request by the Francis Crick Institute in London to modify human embryos using the new gene editing technique CRISPR-Cas9. This is the second time human embryos have been employed in such research, and the first time their use has been sanctioned by a national regulatory authority. The scientists at the Institute hope to cast light on early embryo development—work which may eventually lead to safer and more successful fertility treatments.
The embryos, provided by patients undergoing in vitro fertilization, will not be allowed to develop beyond seven days. But in theory—and eventually in practice—CRISPR could be used to modify disease-causing genes in embryos brought to term, removing the faulty script from the genetic code of that person’s future descendants as well. Proponents of such “human germline editing” argue that it could potentially decrease, or even eliminate, the incidence of many serious genetic diseases, reducing human suffering worldwide. Opponents say that modifying human embryos is dangerous and unnatural, and does not take into account the consent of future generations.
