- Q2As the pond plant shown below photosynthesises, bubbles form around its leaves. Which gas is in the bubbles?nitrogencarbon dioxidehydrogenoxygen30s
- Q3What is an independent variable?a factor that is measured during an experimenta factor that is kept the same during an experimenta factor that is changed during an experiment30s
- Q4What is a control variable?a factor that is measured during an experimenta factor that is changed during an experimenta factor that is kept the same during an experiment30s
- Q5When investigating the effects of light intensity on the rate of photosynthesis, which of the following are control variables?Users sort answers between categoriesSorting30s
- Q6Why is it important to control the temperature in this experiment?because temperature affects the colour of the pondweedbecause temperature can affect the ight intensitybecause temperature can affect the rate of photosynthesisbecause temperature affects the amount of water30s
