AQA GCSE Biology Unit 2 2017

Hello,
I am taking my GCSE exams this year and i was just wondering what predictions people have made for what 4 markers and 6 markers that could possibly appear in the exam for Unit 2 Biology this year. Any suggestions would be nice as i am trying to revise as thoroughly as possible. I am mainly asking as i want to make flash cards for the possible 6 markers and memorise the answers from mark schemes from past papers.
Thank You!

for the losing ions i said kidneys as urine and lungs as water vapour but apparently its lost from the skin as sweat? the skin is an organ?
Cells, enzymes and inheritance
yes skin is the largest organ in the body as it is a collection of tissues joined in a structural unit to serve a common function.
