Answer 1

Answer 2

ITs genes not chromosomes its impossible for the answer to be chromosomes

Answer 3

Good for the person with the realy long answer, you got everything right but the bacteria one which was the range  and also the gaurd cells were below the leaf to prevent water loss. Besides that you will probably get a decent score on the exam.

Answer 4

What did you guys put as a answer for question #2????

Answer 5

Does anyone know if the answer to the question about DNA in protein synthesis: what section of the DNA is used? I put genes. None of the answers seemed to make sense.

Answer 6

The curve:

http://www.emsc.nysed.gov/osa/concht/08/...

question 1 with charts asking which row had only hetertrophs: row a

moldy bread question: gene expression affected by environment

experimental plan: don't need conclusion based on data to be collected

kangaroo without placenta: nutrients

bacteria reproduction chart: at higher temperatures bacteria reproduce at a higher rate

paper chromatography: separating molecules

cell with 15% salt solution: one with intact shape and size (cell wall) but shrunken cell membrane, along with the vacuole (large white figure and organelles)

drawing of dialysis tubing: iodine (x's i think) were equal inside and outside the cell, and starch remained where it was before (circles; cant remember where they were in the beginning)

short answer on dumping leaves and grass into landfill: larger landfills which introduces toxic wastes to more of the environment

replacing forest with farming land: trade-off

source of energy: ATP

enzyme affecting mitochondria would affect: energy made or respiration carried out

why we havent done genetic engineering on humans: ethical problems and dilemmas

multiple short answers on stomates/guard cells:

- life function that is controlled/assisted by guard cells: regulation is the best answer, but i think theyll accept nutrition, since that is technically photosynthesis. not sure if theyll accept photosynthesis because it is not one of the main life functions

- they do this by: controlling water entering/leaving the plant OR gas exchange

- why it is advantageous to have guard cells close to ground: water is found on the ground so you can absorb it

width of cell: 800um

redrawing of virus with circles: you had to draw the virus the same but with triangles instead

how virus would get this adaptation: I said genetic mutations..but this was a tricky question

i looked it up after but i still dont understand it

relationship between human and virus: host and parasite

Answer 7

The one about what determines a ecosystem: I put # of carnivores, but I heard it was climate

The graph that asked for the carrying capacity: Day 8

First Question Part D w/ the diagram that had the paper towel- Was a stain

Answer 8

genes is correct

I'm pretty sure it's genes for that question with the unwinding DNA

Answer 9

which question? cuz the one with the whole unwinding DNA picture the answer was chromosomes i think.
