The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

C) No, because their work has not been reviewed by other scientists.

Explanation:

Although the experiment that Trey and Randall conducted does have a lot of the qualities that are needed in this type of scientific experiment, it would still not be considered valid scientific research. The two are missing an important step that is necessary for the research to be valid. They need to present their work to other scientists, who will then review it as well. This process is called peer-review and is an essential element of legitimate scientific research.
