Living Environment Regents?- so nervous of how i did! 10 pts!?

Question

what was similar between photosynthesis and cellilar communication?

kangaroo placenta: nutrients

how many points do i get if i did the whole graph part right?

the blood and insulin thing i did pancreas

for the trash and landfills, i did it gets mixed with the trash and cn be toxic and cause pollution

for carrying capacity i did day 8

for hypothesis i did the more light you give the plant, the more it will grow

and for the non renewable resource for the electricity thing i did oil

animal energy: atp

for the 15% salt one i chose the smallest one

for chromotography i did: seperating molecules

for electrophoresis i said: cutting DNA fragments

bread mold: i did environment effects genes

for genteitc engineering i did: elogical something

for something i did climate condition

for least likely to compete i did: b and c

for wolf and coyote i said the wolf a nd the coyote would compete be cause they both have the same prey

judging by those answers, how do you think i did?

Answer 1

loks like u did pretty solid if u ask me

Answer 2

i pretty much agree with the above poster's answers except for the bacteria reproduction I got that each species reproduces within a different temp. range or sumthing like that.

Answer 3

Looks good!

Go to jmap.org because they might have the answers and everything out by the end of today! (Hopefully)

:)

Answer 4

sounds good, although for the 15% salt it was the same size as the original, but the cell membrane shrank

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

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)

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

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
