For the alzheimers question I said healthcare was getting better and people are living longer and so there are more elderly people in the world, and seeing as alzheimers affects the elderly it would make sense that thered be more alzheimers cases I hope its right
Is it not because everyone that has it passes it could pass on the gene to their offspring and as population increases so too does the number of people with gene .0 -

Personally I didn't really like the short questions compared to the exam craft pres ones..
I suck at experiment questions as I know nobe of them, but so happy with the two that came up
The long questions I did the ones with text included.. I thought they were hit and miss..0 -

Answer the following questions in relation to carbon dioxide.
(i) Name a structure found in cells in which carbon dioxide is produced.
(ii) Give a feature of a capillary which allows the rapid uptake of carbon dioxide.
(iii) Carbon dioxide levels are usually higher in venous blood than in arterial blood.
Why is this the case?
(iv) Name a blood vessel which is an exception to the situation outlined in (iii) above.
Give a reason for the exception.
(v) Briefly outline the role of carbon dioxide in the control of the human breathing rate

For the last part of the lymphatic short q I think I fecked up
I assumed, for some reason, they were talking about what blood vessel the lymph reenters the blood at, so I said Subclavian Vein, but now Im thinking in was probably Vena Cava
I think I said vena cava for that
But dont worry youre like one of the smartest most prepared person on this forum Ive seen I wouldnt get too worked up over one question:P0 -

Mitochondria, feature: moist for diffusion, co2 due to respiration deoxygenated blood etc, pulmonary vein as it brings oxygenated blood from the lungs etc, co2 level: high will increase blood ph which encourages heavy breathy: medulla oblongata regulates it etc..

ii) Thin walls only one cell think
iii)I wrote something really long for this but basically arteries take oxygenated blood straight form the heart and veins take waste products from the cells back to the lungs to be exhaled I cant remember exactly what I said
iv)Pulmonary vein
v) I wrote a long bit for this too, but brain monitors blood acidity levels. When theres too much co2 the PH in blood drops as its an acidic gas, brain alerts ribs and lungs to exhale to breathe out the c02 0 -
