In a lab experiment, students had four samples of elements. They made observations about the appearance of each sample, then proceeded 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?

What is the role of dna ligase in the elongation of the lagging strand during dna replication?

Astudent sees several ants walking up a wall following the exact same trail that an ant took earlier. she wants to apply the scientific method to determine how the ants detected the trail. which of these steps would come first in her application of the scientific method? perform an experiment by cleaning the scent away from part of the trail. draw a conclusion that the ants follow a scent trail. make a prediction about what the ants will do after she cleans away part of the trail. hypothesize that the ants are following a scent trail that the first ant left.
