Techniques for estimating the number of yeast cells in a culture... - Serial dilutions - Spectrophotometer - Compound microscopes - Estimating concentrations from a calibration curve What is an important single-cell organism? Yeast If you want to dilute yeast 1/10 - how much yeast and water would be in the dilution? What about 1/30? 1/10 = 1 ml yeast/ 9 ml water 1/30 = 1 ml yeast/ 29 ml water Spectrophotometer An instrument that measures the concentration of solutions by shining a beam of li...

KSU BIO 198 Module 5 Questions and Answers Rated A+ Describe the first law of thermodynamics and explain why it is important to cellular energetics 1st law: energy cannot be created or destroyed, only transferred or transformed. No living thing can create its own energy, only transfer it from somewhere else describe the second law of thermodynamics and explain why it is important to cellular energetics 2nd law: during energy transfer, some energy is lost as heat. Therefore any transf...
