<p>^ Was the answer plasmids?</p>
<p>i left that one blank… oh damn so that s 8 omit for me!</p>
<p>what was the question? conjugation between two bacteria is the swapping of plasmids.</p>
<p>(i took ecology section, and i don’t remember seeing that problem)</p>
<p>it was about conjugation between bacteria being interrupted so that only part of it happened. what applications does this have?</p>
<p>To determine the locations of genes.</p>
<p>Ohhh, that question. I completely guessed on that one, I think I said it determined the location of genes</p>
<p>i remember question like that in the PR book. The answer there was to determine the location of genes. It makes sense, too.</p>
<p>Mendel said nothing about- crossover
somatic body cell of 24- 12 from each parent
APES- not the brain cavity =(
Farm runoff- decrease in eutrophication?
Bacteria 5- produced toxins
pH 4.5 - 5.5- H+ decreasing
Bacteria #6- came from water
Really high concentrations- balanced fertilizer
Soil most likely to resist temp. change- wooded forests
Calvin Cycle- bundle sheath cells
Archaebacteria- similar to eukaryotes
Segmented seperation- annelids(earthworms)
light reactions equation- H2O -> O2
Pea genetics question- 50%
Wool genetics problem- 3/4
Cytosine- Guanine
Bases per Gene- 1000
Restriction enzyme- A
Bacteria- ammonia
Greatest Biomass- plants
Carbon Rocks- comes too slowly
Ventrel nerve cords- arthropods
Large intestine- watery feces
Evolution in populations - the one with 4, 5, 6
Substance causing growth - IAA
Identifying unknown microbe - Plants and protists
Mitosis diagram - III and IV
Coenzyme - Vitamin B12
Something that acts to lower activation energy - Amylase
Steroid that influences metabolism - Testosterone
Inorganic molecule that has a regulatory function - Calcium (mineral)
Incomplete Bacteria Conjection- determines location of genes</p>
<p>debates:
Colorblind Son genetics problem - 1/4 (prob of having colorblind son) or 1/2 (prob that their son will be colorblind)
Pea plant problem - 250 (homozygous dom) or 500 (homo dom + homo rec)
plant control - 1,2,3 or 2,3
Ape and early human - not brain cavity, smaller upper jaw?
.9 Solute- swell and burst?</p>
<p>I remember one question dealt with the denaturation of a protein. Anyone else know this question in greater detail?</p>
<p>the question was what happens at 40 degrees and the answer to that was denaturation</p>
<p>I am almost 100% sure about the swell and burst, Mandizz.</p>
<p>Cell’s contents are about 0.9% solute solution, and if you put the cell in distilled water, osmosis will move water into the cell, because the cell is hypertonic compared to distilled water (0% solute solution). Water will keep moving in until finally the cell bursts. In Bio lab we had fun bursting cells. 
(evil, i know)</p>
<p>the only way that “swell and burst” is not the answer is if I read the question wrong. Forgive me if I sound cocky - I’m not. Today’s bio was HARD.</p>
<p>so far i omitted 6 and got 6 wrong =(…thats a raw score of roughly 66.5 which rounds to 67. if i got 2 more wrong then ill have a raw score of 64. whats the lowest i can get for a 700+? i know im tipping the border, but i just want my 700 so i dont have to retake =(. if i get a raw score of 64 will i get lower than 700?</p>
<p>so far i omitted 8 and got 4 wrong… wat would that bring me? a disaster or a happiness?</p>
<p>according to the Princeton Review book, a 64 is a 690.</p>
<p>and brbcya, according to the same book, 67 is a 710</p>
<p>One possibility merging the two pieces of evidence we’ve got, maybe the brain cavities were the same size, but the brains were different sizes.</p>
<p>what is society of ants? giving jobs to workers or breaking off large population</p>
<p>also, in 20-29 age group females why 0% mortality rate? Because of high death rate in pre-20 years? Is this right?</p>
<p>Okay, on that friggin stupid ape brain question:
read this article:
<a href=“http://news.bbc.co.uk/1/hi/sci/tech/3496549.stm[/url]”>http://news.bbc.co.uk/1/hi/sci/tech/3496549.stm</a></p>
<p>It basically states that in the past, brain sizes were thought to be the main difference between hominids and apes. However, new evidence was found in a "human-like primate’’ fossil, compared to an ape. Brain/skull sizes were similar - the only difference was the position of the “primary visual striate cortex (PVC)”.</p>
<p>I’m not sure how to interpret that. Does the PVC count as a difference in neural channels or a difference in brain cavity?</p>
<p>By the way the article is dated 2004. THis is stupid. Why would collegeboard expect us to know this?</p>
<p>I totally guessed that a society of insects differentiated and assigned jobs to workers.</p>
<p>FOr that question, I guessed that the mortality rate was 0% because the sample collection was too small, therefore there was room for sampling error. Also because none of the other choices made sense.</p>
<p>Wasn’t there some question about a Beech/Mixed Deciduous forest? I chose Mixed Deciduous though I thought it might have been Beech, but that the population of the other trees wasn’t going down significantly enough for them to actually be eliminated in 50 years…</p>
<p>was it just me, or was that problem with the genes of h.influenzae confusing? i didn’t understand what the problem was asking, so i left it blank.</p>
<p>for the IAA one was the answer for how do we know that IAA stimulates root growth that number 4 grew roots earlier than number 5 or 3 or something/</p>
