How was the living environment exam?

Question

i think i did gud, but i want to get more then 85.

what about u?

Answer 1

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

thats rong, everyone is riting that the answer but its not

its the answer that said like bacteria can only reproduce at certani tempretures and this is because wen the temperature got hotter  bacteria A wold die out and as it was dying out it would cross with bacteri B becuase it can only reproduce at that temperature and so this shows that bacteria can only reproduce at certain temperatures

it is a trick y question though

Answer 2

SOME ANSWERS

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)

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

To get atleast an 85, you need above a 66/85

Answer 3

To pass with Mastery, you have to get an 85 or higher on the Living Environment Regents. There were some hard (tricky) questions on there, but I believe that I got at least an 85. It is an easy regents to pass, but not easy enough to get 100% unless you're a super-genius or something.
