Question

Anna is a microbiology student. She was doing a research on optimum temperature for the survival of different strains of bacteria. Studies showed that bacteria X need optimum temperature of -31˚C while bacteria Y need optimum temperature of -56˚C. What is the temperature difference?

Answer 1

Answer

(-31)-(-56)=25

therefore difference is 25°C

Answer 2

Step-by-step explanation:

difference between bacteria X and Y =

X-Y = -31-(-56)=-31+56=25
