Which of the following describes the primary mechanism by which certain microalgae species can tolerate and even thrive in environments with extremely high salinity, such as hypersaline lakes?
Question 2
In the context of microalgae cultivation, if a culture is experiencing significant 'nutrient drawdown' where a specific nutrient is rapidly depleted, which of the following physiological responses would be observed, and what is its long-term consequence for biomass production?
Question 3
Which of the following best describes the 'packaging effect' in algal photosynthesis and its implications for light absorption efficiency in dense cultures?
Question 4
A strain of microalgae is being evaluated for its potential in bioremediation of wastewater containing high levels of nitrates. If the initial nitrate concentration is $100 \text{ mg/L}$ and the algae remove $15\%$ of the nitrate per day, what will be the approximate nitrate concentration after 3 days, assuming exponential decay?
Question 5
Which of the following physiological adaptations allows some macroalgae to efficiently absorb nutrients from a dilute water column, even when nutrient concentrations are very low?
