I believe the one with the contractile vacuole, not sure if there was a different one.
@k_atherine.h Same…I was pretty vague on that question…
Can we retake it in august? If I get lower than a 94 i’ll retake it
They can’t teach us osmosis is with water, how are we supposed to know that they use ATP to do this? Its water diffusion
yeah we can, I didn’t study 1 minute for this regents today but it was still easy lol
We were taught that water leaves in high concentration through passive transport, just NYS being typical NYS
no osmosis is passive transport - no energy required
@k_atherine.h I agree it was a weird question, but you had to reason that if the water would naturally diffuse out, the contractile vacuoles wouldn’t be necessary in the first place. Also, I saw a question like that on a practice regents. For the second part of that question, I picked 4, that it was correct because salt would diffuse out.
It has to be passive transport like come on…
I would not suggest retaking if you get above an 85. The August grade will probably likely not go into your transcript and will not be counted for you average in the class this year.
I’m expecting nothing lower than a 90. If its significantly lower (i don’t know how) I will retake it in august
but the vacuole had to contract to expel the water, it didn’t just happen. It required energy to do, so it’s active transport. The osmosis thing was confusing though- i spent a while on that question
Osmosis does not require ATP since it is a form of diffusion.I am so grad that I made these regents threads.
this process is called osmoregulation, in paramecium two contractile vacuoles which are connected to the cytoplasm by means of radial canals. When there is excess water in the cytoplasm it travels through the radial canals and into the contractile vacuoles which then expel the water outside the body and this is called Osmoregulation. So it’s passive transport…
Is it ever possible where NYS will take out a question because it is so bad?
I was pretty confident in active transport, it also really helped to read the accompanying multiple choice question with it (sort of gave it away that it couldn’t naturally be passive transport.)
what was the multiple choice with the salt and movement of water question that was tricky
I probably got a 95, 96 or 97 if it was natural resource. My goal was a 100, but the test questions were way too confusing, making it nearly impossible to score perfectly
It seems like the contractile vacuoles would use ATP to expel the water, but osmoregulation is something new now
@“Albert G.” It was a question that had the answer choices 0%, 95%, 97%, and 99%. I picked 99%
