The tail provides electrons which are the ones that get excited and move to higher energy levels when light shines on the chlorophyll. . Then you go ahed and explain further..
What about the one of investigating water and light?? And the detection of the cancer on blood or plasma cells?
water... take the sample of soil place it in oven measure the intial content ie mass and after heating allow it dry..measure the diffference in mass which gives u moisture content. light........use light sensors

I did mention the light exciting electrons and this boosting to higher levels and blabla However i didn't specify that the tail provided the electrons... Hopefully i can get some marks

I wrote that to measure water you get a sample from the soil and weigh it, then you dry the sample and weigh it again. Then to measure light use a light meter. I did add too that this measurements should be repeated to ensure reliability since they can vary depending on the season of the year or the time of the day. Just in case since they were 3 or 4 marks (can't remember exactly) haha
For the detection of cancer on blood sample i wrote that you get a blood sample and compare to a healthy blood sample, which will have the normal number of white blood cells, platelets and red blood cells and plasma cells will have a normal shape. Therefore you count how many they are in the blood sample and depending in the number of them and shape of plasma cells, they would have cancer or not.

The weird one was that about the jigsaw puzzle. I wrote about carbon cycle, co2 being released
Yeah what do they mean with freakin jigsaw puzzle ; i didnt get it i just wrote that they didnt know where the carbon from the atmosphere was dissapearing and that it was accumulating like a carbon sink in that peat

I mentioned the carbon cycle too. That one was really weird
My son sat unit 4 Biology today and sits Unit 4 Chemistry on Thursday. He said today's paper was like nothing he had seen before. A lot of suggest questions and less knowledge based. Over his 5 x AS levels he averaged 90%. He was so upset about the exam today. He didn't even finish the paper. One very upset son
