What did everyone put for the B3 6 marker? confused me quite a bit
For the first 6 marker, I measured the "diagram" and it came out as 25mm, 5mm longer than the original 20mm plant stem. So then I did (5/20)*100 to get an overall increase of 25%. From here I looked at the graph and went to the 25% percentage change reading on the y axis and went across and down to find the answer, which I got as 28 parts per million.
Not sure if this is correct, but this is all I could think to do. I sat staring at the question for ages until I realised I might need to measure the "diagram" that was just a rectangle!
What did everyone put where you had to fill in the 3 blank spaces for the question on gene mutation and inheritance on B1?
