June 2008 Living Environment Discussion Thread. Lets Discuss?

Question

Paper Chormotacgraphy= Separtation Molecules/ Related with gel electropherisis.

not needed in experiment = techonology one

one of the question asked about decrease because of farming

i think trade-off one im not sure of

most SYNTHESIS of energy is ATP not glucose

glucose is a direct source of energy but it cant synthsized energy only ATP can. i already asked my teacher it was ATP

enzyme mitochondria one was

the nutrient/energy

geographical is ecosystem is affected by CLIMATE.

gene insertion in DNA

was defeintely the ethcal problems one im sure

Answer 1

I tried so hard

Answer 2

what isnt it mitochondria so it cant be atp. The source is the glucose. anyone, i put atp, but changed it to glucose. oh well

Answer 3

no one's going to remember that.

Answer 4

no one...i got similar MC answers as you but i disagreed with about 10

Answer 5

Anonymous is correct...you cannot make a conclusion based on expected data. Overall, the regents was EASY except for the guard cell question. The third bullet there is still some debate.

Answer 6

if anyone rote down their number to each question

here is what i got.. and I am not a dumb kid so this is pretty relaible i have a 95 avg in bio (im not trying to be ahsow off im trying to help you guys out with my answers)

I hope this helps

Part A - 141431142334243321122231224313

Part B - 424121424132

to answer the question above i was able to rite down the answers because for some reason outr bio teacher wanted us to have scrap paper so i tooke of them at the end and claimed i only recieved one wen i rlly recieved 2.

Answer 7

For the first/second bullet, I put: "Photosynthesis is controlled  by the guard cells because the cells control the movement and amount of water into the cell.  And water is needed for Photosynthesis."  The third bullet I put, "They are located on the bottom to suck up more water."  It's probably wrong bc I was thinking of those found on roots not on leaves, but it apparently can work either way so that's good at least.

Just out of curiousity, how were some of you enabled to copy down the answers?

Answer 8

for the guard cell question...for the third bullet where it asked about the leaves on the ground...i said it absorbs more water that is in the soil or something like that

the test was very easy overall except for that question

Answer 9

Wait, for not needed in the experiment -- I thought it was a conclusion for the data that is to be collected. You would need instruction on how to use the technology, right? And if you haven't collected the data, how are you supposed to conclude?

paper chromatography: separates molecules

kangaroo w/o placenta: nutrients

~~~~~~~~~~~

Thanks to the person below me. For the stomate/guard cell question, for the 3rd bullet, there is only one possible answer.

- advantageous to soak up more moisture, found on soil and grass

For the 2nd, you could've put gas exchange or water absorption.

BUT for the 1st, what function was it?

Oh, and the bacteria temperature was that an increased temperature causes higher reproductive rates. It wouldn't be that individual species reproduce at specific temperatures because most were able to reproduce at 20 different degrees or temperatures. (C)

Answer 10

the guard cell was easy...

Answer 11

what did you put for the guard cell one and what about the one with the bacteria temp i think that one is debatable as well.

Answer 12

the paper chormotagraphy was that choice 1? i remember i kept changing my answers but i picked that one and i forgot what one that was haha
