SATII Biology MAY

<p>anyone remember some of the answers on the test?
- like the tropisms in the classification section
- the ecology section</p>

<p>thanks!!!!!!</p>

<p>birds reproducing in the summer was a tropism but i didn't know what it was.
another was the plant to the sun.
i didn't know the one where the sap was removed and passed through an ultrafilter and then injected into a normal fruit, it made the normal fruit diseased. do you know what it was? virus or bacterium?</p>

<p>gah the answers virus cause its smaller than bacterium (even though i guessed bacterium)</p>

<p>do you remember the one with the pedigree? i couldnt choose between 6 and 5 and6 only.</p>

<p>it was definitely 5 and 6 because it was autosomic recessive so it needed 2 recessive alleles from both carrier parents to have the disease</p>

<p>oh thank goodness haha what do you think the curve is going to be like?</p>

<p>pretty hard, the curve is always around 3 or 4 wrong max to get 800. what did you get the for bog plant one? the soil lacks carbon or nitrogen which makes it carnivorous?</p>

<p>thats a harsh curve. whats like "good" for very selective colleges? i said nitrogen</p>

<p>I guess anything above a 750 for very selective colleges. And what did you put for the last question. I think it was something about antibiotic and why the curve dropped...</p>

<p>i took the E so i wouldnt be able to tell you.</p>

<p>it was D, the bacteria already had resistance, an antibiotic can't cause a bacteria to have a resistance?
how come its nitrogen? its carnivorous because it can't produce sugar most likely and all the sugar derives from carbon. so that was my reasoning for choosing carbon.</p>

<p>It would need a source of nitrogen if the soil is low in nitrogen. And I guess the only way to do that would be to 'eat '....not sure though.</p>

<p>wouldn't it also need a source of carbon? or that just come from the carbon dioxide in the air. crap i think its nitrogen.</p>

<p>guo123, thats what i was thinking. cause nitrogen is a macronutrient (which kind of goes along with another question.. that fertilizers have inorganic materials, like nitrogen and phosphate, to help plants grow)</p>

<p>okay here are my answers:
planaria - phototaxis (correct answer)
mutation ? - DNA triplet
Parathormone - I only (anyone else?)
plasma membrane - common
cell wall
asexual rep. for the angiosperms/vertebrate one
inorganic cmpds for fertilizer
nitrogen fixing bacteria
0% for white tall
a lot of 50% things
parathormone - neither will produce TAT and mRNA
I and II only for that dihybrid independent assortment with 9:3:3:1 ratio
hmmm - and ovary for cell 2
i was done in 40 mins
3 experiments - 2 responded to touch
virus</p>

<p>oh yeah, nitrogen, omnivore...</p>

<p>is chromosome aberattion a mutation?
or was the answer DNA triplet
or was it post - transcript RNA</p>

<p>mutation DNA triplet? i don't remember that one. and the parahormone what were the answer choices?
for the 3 experiments i had one touch, one light, and one temperature. the seed one wasn't touch cause they drew in the dark with water</p>

<p>I was confused on the DNA mutation question. Why would it be the triplet? If a triplet was gone then wouldn't it be a frame shift and therefore a mutation?</p>
