    Hello sir, just wanted to let you know that I got an A* in Biology, your short videos really helped me, especially for Paper 5 (you might remember my comments the day before exams)
    Thanks once again sir, I'm really grateful!

    Hello sir,your video was really helpful in making me understand the topic but I had a question that why did we use the glass beads inside the respirometer when not using soda lime?
    Thanks

    • @DBiologyClassroom

      Hi, those beads are to take up the space of soda lime, to compensate for the volume so it is the same.

    I thought plants breathe in CO2 not O2?

    • @DBiologyClassroom
      @DBiologyClassroom  6 месяцев назад

      ALL organisms carry out respiration. Plants only take in CO2 when they start photosynthesising.
