Neco Model Questions Vol1 2023 Biology Question 37
Practice objective / multiple choice question 37 from the 2023 Neco Model Questions Vol1 Biology examination.
A bacterial culture starts with 2.0 × 10³ cells. After 3 h at 37 °C the population reaches 1.6 × 10⁵ cells. The generation time at 37 °C is therefore constant. When the temperature is lowered to 30 °C, the generation time increases by 50 %. Assuming exponential growth continues, how many cells will be present after a total of 8 h (the first 3 h at 37 °C followed by 5 h at 30 °C)? Give your answer in scientific notation to two significant figures.
