Answer:
Step-by-step explanation:
Given that " Katherine is conducting an experiment with bacteria "
Also given that she cools the temperature of one bacteria to -51 and the other bacteria to -76.
Let x be the first experiment of one bacteria to -51
Therefore x=-51
Let y be the second experiment of another bacteria to -76
Therefore y=-76
Let z be the temperature difference in the two experiments
Now the temperature difference in the given experiments is given by
z=x-y
z=-51-(-76)
=-51+76
=25
Therefore z=25
