What were the answers for the exocrine stuff
Original post by Shy100
What do u guys about that

No clue, normally i remember the paper but I forgot loads of it

For the EPC did anyone put that it wasn't safe because it could cause uncontrolled cell division?


I skipped that one

I would say it stuck to what but the topics it told us to put the most focus on was all cap.

How many marks was that
Original post by borat32
I only talked about xylem would I lose marks then ?

It said two visible adaptations,

Spiral Lignin - flexible support

Plasmodesmata (the holes in the walls of the phloem tube) - allow sucrose to diffuse in from companion cells

If you found two adaptations for the xylem part you would get the marks, didn't have to mention phloem I think

2 Marks or 4 marks i think.
What did you guys put for the lack of atp when dead causes muscle rigidity

Endocrine definition- Hormones are secreted by endocrine glands such thyroid gland releasing thyroxine and is released straight into the bloodstream

Exocrine- Pancreatic juices or enzymes move through the pancreatic duct and into the duodenum at the top of the small intestine before being released therefore it’s exocrine tissue

Instead of plasmodesmata if I wrote perforated wall to allow transverse water movement would I get that

Calm I said no end cell walls to provide a continuous flow of water to maintain transpiration pull. And then bordered pits to allow lateral movement of water into cells and tisssues
i said ATP releases less energy to muscle cell so less effective contraction...

If I wrote for the 1 marker secreted via ducts would I get the mark

Im sure u would get it

Kl thx

But the guys dead innit?
I put that the myosin can’t be removed from the actin filament because less atp to bind
What was the anomaly please
