Which of the following details BEST reflects the primary goal of creating models to simulate how matter moves between galaxies? A A recent study published in Monthly Notices, the journal of the Royal Astronomical
Society of the United Kingdom, used computers to try to estimate how galaxies
grow and shrink over time.
B More specifically, it modeled how matter moves between galaxies and how travels
through space in huge, fast clouds.
C "Science is very useful for finding our place in the universe," said Daniel
Andamientos-Alcázar, a scientist who worked on the study.
D In a way, he said, we are only visitors in the Milky Way, since most of the matter that
forms us comes from other galaxies.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
