      @hoanganhha687 6 днів тому

      For wxample if the gap between 1 and 3 is 8 squares and the gap between 3 to 6 is 8 squares it is equidistant but if the gap between 1 and 3 is 6 and the gap between 3 to 6 is 7 it is not

      @clarebiology2858 День тому

      yes as @hoanganhha687 says- it’s using the same intervals on ur axis e.g going up in 5s or 10s or 3s so there is an equal distance between each of your axis points 👍

    hi , could you please explain the first exam question in the video ( the CO2 uptake) I don't understand how the question corresponds with the ms answer.

    • @clarebiology2858
      @clarebiology2858 День тому

      You can measure o2 given off or co2 used up as an indication of how fast photosynthesis is occurring. here it asks u why measuring co2 might not be accurate 👍
