can someone explain the topic of tissue fluid?
At the arteriole end, there is a high hydrostatic pressure, forcing plasma out of the capillaries. The RBCs, WBCs and platelets remain in the capillary because they are too large. This results in a more negative water potential in the capillary.
At the venule end, the water potential is lower in the venule that the tissue fluid, so plasma moves into the venule.

Hope this helps

Before you say anything, no I'm not sponsored by this guy or anything, but if you search Mr Pollock biology on youtube, there's a good playlist for unit 2, with most of the topics covered

dont need to know it in detail for aqa, all you need to know is that for crossing over, chromatids of different chromosomes will wrap around eachother, snap off and exchange alleles. Independent assortment is literally just that they line up in random orders each time the cell goes through metaphase, however it only really affects the genetic diversity during meiosis really.

Do ypu have the cgp evision guide Book ?As in the big thick one ?It has plenty of good exam style questions and application questions.The nelson thornes book also is good.
Watching youtube videos also helps.On the day of the unit 1 exam,by a chance of luck,that morning I was watching youtube video of a baby with whooping cough.
