Q 15 ans is the nutrient one? Or bacteria?

I put bacteria

I thought it is bacteria....
i have done this question before and the explanation was that the bacteria would have algae growth and the algae on the surface would block out the sunlight.... unsure

Regarding about the question about the steel and glass metal plates, MCQ.


Steel is a better conductor of heat than glass. Hence, steel will gain heat faster than glass. Heat on steel will conduct heat away faster than glass causing steel to be cooler. Water vapour rises on the cool surface of the metal plate, condenses to become water droplets. Therefore, steel is a cooler surface than glass. [Explained by me, hope you all will understand. :D]
