ACTIVITY 5: DNA Just as we studied the DNA of the different plant species in our NYS Biodiversity
Lab, scientists study the DNA of different species all the time in order to determine
relationships between organisms. As we know from our last lab, we cannot rely on
structural characteristics alone, the DNA evidence is always going to be the most
reliable of all of the evidence addressed in today's lab. DNA sequences contribute
to such molecular evidence as enzymes, hormones, and pigments present in

What noticeable trend from this graph might be used to make a conclusion?

A(n) is a molecule influences the way that a molecule reacts.

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.
