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?

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

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

Accepted Answer

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

Question 10

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

Accepted Answer

Cells undergoing meiosis will show greater genetic variation than those undergoing mitosis.

Question 11

Question 14

During the DNA lab, students extract DNA from strawberries. Which of the following best explains why strawberries are a good choice for DNA extraction?

Accepted Answer

Strawberries are octoploid, meaning they have eight sets of chromosomes, which increases DNA yield.

Question 15

Which of the following is a correct application of the scientific method in the context of the course labs?

Accepted Answer

Developing a testable hypothesis, conducting an experiment, analyzing data, and drawing conclusions.
