In a lab experiment, students had four samples of elements. They made observations about the appearance of each sample, then pro
ceeded to conduct three separate experiments. In the first, they found the melting point of each by holding small samples in a Bunsen burner with a temperature probe. In the second, they held a conductivity probe to two separate sections of the sample. In the final test, they took a small sample and hit it with a hammer. What is the most significant similarity between the first and third trials, as compared with the second one?
Organisms from the same genus must have features that can make them part of a same group like anatomic features, however if the organisms cannot produce fertile offspring if they interbred each other they are not from the same species.
