Q: According to the syllabus, what is the correct formula for calculating your final grade percentage in the course?

$\frac{\text{Total points earned}}{100} \times 100$

Q: During the respiration lab, students measure the rate of oxygen consumption in yeast. If the initial oxygen concentration is $8.0\,\text{mg/L}$ and after 30 minutes it drops to $6.5\,\text{mg/L}$, what is the average rate of oxygen consumption per minute?

$\frac{8.0 - 6.5}{30} = 0.05\,\text{mg/L/min}$

Q: If a student receives the following scores: Practical Exams = 28/30, Lab notes = 45/49, Quizzes = 19/21, what is their total percentage score?

$\frac{28 + 45 + 19}{100} \times 100 = 92\%$

$\frac{28 + 45 + 19}{100} 	imes 100 = 92\%$

Question 10

Which of the following is a plausible hypothesis for the mitosis/meiosis lab?
