what in christ’s name were the three proteins

I ruled that answer out because I thought constant level was incorrect 😭

in that answer did it say maintain at a constant level for ALL animals- i may be wrong but dont ectotherms usually have varied body temps??

stopp I wrote thermometer and was thinking water bath but the q said it was really big so I was like nah probably not that omg bye I’m acc done

I did 25,20,15,10,5,0 and 5,10,15,20,25,30

guys help if you write beyond line but are still within all borders do they still get marked?? i wrote few lines after because I had to cross out previous answer so you know that insert one where we had to describe to features/function of the xylem thing, I crossed out my entire first line because it was wrong so I had to draw an arrow below to write it!! will that be fine?/

Guys, you see the black L-shaped lines at the bottom and top corners of the page and a thin grey strip at the side that says "DO NOT WRITE ON THE MARGIN" which I have tried to demonstrate in the image attached. I am a bit worried because I wrote outside the black L-shape parts for the biology exam many times (shown by where the arrows are pointing to in the image attached) when I was lacking space on lines and had to continue my sentences off the line. But I didn't write on the thin grey strip that said "DO NOT WRITE ON THE MARGIN". Did I write in the wrong places which will not be seen by the examiner?

U have to do the concentration x 30 to get volume of sucrose. So 0.2 M concentration is 0.2 X 30 = 6 cm3 of sucrose or whatever and then the water is 24

Actin myosin and tryptonin (idk how to spell the last one) is what I put down

If you put the 25, 20 etc. would you lose all 3 marks?

What is the correct way of answering "evaluate the conclusion"

what was the insert? was it xylem because we could see lignin what did you say about how its adapted??
what was the leaf diagram showing what was A and B???
and what is pluripotent

Ectotherms don't use homeostasis to regulate temp, but the ALL animals is weird I agree. Seemed like the best option tho, the other 2 options included positive feedback and the last one said sensory receptors coordinate response which is wrong, so idk tbh...
