Al Response To determine how many generations are expected to form in Experiment 1, let's evaluate the situation step by step: 1. Environment Analysis: Medium: The experiment is conducted in a YPD liquid culture, or Yeast Extract Peptone Dextrose broth. This is a rich medium with a nitrogen source that is often used to propagate yeast, and it is considered an optimal medium for S. pombe. Verdict: The optimal medium will increase propagation by 40%. Food source: Maltose is provided as the available food source. While this is usable food for S. pombe, it is not as favorable as glucose due to being a more complex disaccharide. Verdict: Glucose is not present, so there is no propagation increase. Nitrogen: The peptones and yeast extract in YPD contain nitrogen. Therefore, a nitrogen source is present. Verdict: The presence of a nitrogen source will increase propagation by 5%. Oxygen: The yeast is being incubated in an airtight sealed flask, which is an anaerobic environment. S. pombe is capable of respiration via fermentation, so propagation will occur at 110% the normal rate, meaning an increase in propagation of 10%. 2. Propagation Calculation: • Experiment 1 was carried out at 30°C for 8 hours. Table 1 indicates that 8 hours at 30°C under standard conditions will see 2 generations propagate. Therefore, 2 generations would be expected to propagate in 6 hours at 30°C under standard conditions. Adjusting for the conditions in Experiment 1, the standard propagation is increased by 40% + 5% + 10%: 40% + 5% + 10% = 55% 2 generations * 0.55 = 1.1 generations 3. Final Answer The biologist would see 1.1 generations propagated. Despite the airtight environment, the optimal medium, presence of nitrogen, and fermentation allowed for healthy growth.

To determine how many generations are expected to form in Experiment 1, let's evaluate the situation step by step:
1. Environment Analysis:
Medium: The experiment is conducted in a YPD liquid culture, or Yeast Extract Peptone Dextrose broth. This is a rich medium with a nitrogen source that is often used to propagate yeast, and it is considered an optimal medium for S. pombe.
Verdict: The optimal medium will increase propagation by 40%.
Food source: Maltose is provided as the available food source. While this is usable food for S. pombe, it is not as favorable as glucose due to being a more complex disaccharide.
Verdict: Glucose is not present, so there is no propagation increase.
Nitrogen: The peptones and yeast extract in YPD contain nitrogen. Therefore, a nitrogen source is present.
Verdict: The presence of a nitrogen source will increase propagation by 5%.
Oxygen: The yeast is being incubated in an airtight sealed flask, which is an anaerobic environment. S. pombe is capable of respiration via fermentation, so propagation will occur at 110% the normal rate, meaning an increase in propagation of 10%.
2. Propagation Calculation:
•
Experiment 1 was carried out at 30°C for 8 hours. Table 1 indicates that 8 hours at 30°C under standard conditions will see 2 generations propagate. Therefore, 2 generations would be expected to propagate in 6 hours at 30°C under standard conditions.
Adjusting for the conditions in Experiment 1, the standard propagation is increased by 40% + 5% + 10%:
40% + 5% + 10% = 55%
2 generations * 0.55 = 1.1 generations

The biologist would see 1.1 generations propagated. Despite the airtight environment, the optimal medium, presence of nitrogen, and fermentation allowed for healthy growth.
Answer: 1.1 generations
