Which explanation is consistent with the data collected?
liver cells
The increased mass of the willow tree was the result of the tree taking in materials from its environment.
fresh water and seawater because more species in an ecosystem increases the variety of genetic material available
scientific explanations are tentative and subject to change as new discoveries are made
different cells have the same genes, but the same genes aren’t expressed in all cells
ecological succession
accurate because the average global temperature has risen
the resistant bacteria survive in greater numbers and pass the trait to their offspring
This discovery illustrates the concept that
