Dec-2012- Biology (E/M)

<p>What'd you guys think ?</p>

<p>Not too bad, a couple of random questions that I had no idea about. I picked E, did the questions, and changed to M after I saw that I knew more of the answers… LOL</p>

<p>I skipped 7, and I think I got around 3-5 wrong, so I think I got anywhere from a 690-730ish, 40ish. Guess we’ll just wait and see :)</p>

<p>when is embargo for discussion lifted? i have so many questions!</p>

<p>I think we can go ahead and discuss it.</p>

<p>ok what was the order for secreted proteins?</p>

<p>what type of learning for the cat with the can opener?</p>

<p>What was explanation for short range of enzyme activity?</p>

<p>What explains the various temps for enzymes?</p>

<p>What was unique to the retrovirus?</p>

<p>What was protein x responsible for?</p>

<p>What type of environment provides most primary productivity per area?</p>

<p>I thought it was pretty easy overall. Some questions I had no idea so I just took a good guess, but definitely I thought it was way easier than the November one. BTW, I took the E portion.</p>

<p>I did pretty well, hoping for a 800
Does 1 left put me at 800 guys ?
I took the E cause i knew more answers.</p>

<p>what type of learning for the cat with the can opener? “Habituation.” </p>

<p>What was explanation for short range of enzyme activity? Is the this the DNA polymerase experiment ? the answers for that exp. were </p>

<p>D. 37 C.
A. Enzymes are temperature dependent.
B. Enzymes denature at higher temps.
E. Humans regulate their body temp. while algae do not.
D. Amino acid sequence is different in the three enzymes. </p>

<p>What explains the various temps for enzymes? Refer to the answers above.</p>

<p>What was unique to the retrovirus? I solved E but I’m pretty sure i have the right answer for this one … “Retroviruses code for reverse transcriptase enzymes.”</p>

<p>What was protein x responsible for? I solved that one from M too :smiley: It was “Stimulating cell division.”</p>

<p>What type of environment provides most primary productivity per area? “Taiga” because it’s the largest terrestrial biome.</p>

<p>probably a frequently asked question… but what’s the curve</p>

<p>@Daboss786 I would love to know … Too bad we;re only going to find out the day the scores are out.</p>

<p>what type of learning for the cat with the can opener? “Habituation.” </p>

<p>Nope
that’s not quite true
Habituation is when animal learns to ignore a stimulus when it’s quite frequent
and that one is classical conditioning when animal learns that food will be present by tapping something or hearing a sound it shivers cause it knows something bad will happen
just like the dragon in harry potter and deathly hallows 1</p>

<p>**** i have grassland instead of taiga there
i thought that was about more nutritious lands
everything else i have correct</p>

<p>Retroviruses code for reverse transcriptase enzymes."
i have this too</p>

<p>and enzyme x yes it makes the cell undergo fast mitosis</p>

<p>What do you have in the one with a balloon and which air will fill it?
i was between Oxygen and carbon dioxide but I still circled A
if plants had starch storage so they could photosynthesize? waste product CO2 no?
I thought about cellular respiration because i wasn’t sure the light was present but the next question didn’t include Cellular respiration so i still wrote oxygen</p>

<p>what about carrying capacity thing about deer?
i circled A the first years like when the line was horizontal and stable
all the other periods were going up and down</p>

<p>uggh that was Estuary
i have no idea whatthat is
look at the chart
[Primary</a> Productivity of Biomes](<a href=“ICE3BET: Judi Slot Online Terbaik #1 di Indonesia | Slot Gacor 2021”>ICE3BET: Judi Slot Online Terbaik #1 di Indonesia | Slot Gacor 2021)</p>

<p>So I have that one
also the one with cortex mistake
not sure about deer question</p>

<p>and guys the first one in M was glucose right? in it’s ring structure but it was definitely a mistake because it didn’t contain 6 C s only one</p>

<p>@Bluecholeric My bad “Habituation” was not even an answer on the test. I put the answer as “Conditioning” too … I ****ed up hehehe :smiley: </p>

<p>“What do you have in the one with a balloon and which air will fill it?
i was between Oxygen and carbon dioxide but I still circled A
if plants had starch storage so they could photosynthesize? waste product CO2 no?”</p>

<p>This exp. was tricky indeed. I chose “Oxygen”, because i though of it as the by-product of photosynthesis. I’m guessing we’re right ? </p>

<p>"what about carrying capacity thing about deer?
i circled A the first years like when the line was horizontal and stable
all the other periods were going up and down "</p>

<p>Carrying capacity was A indeed ;)</p>

<p>What was the cortex one ? Can’t remember it at all</p>

<p>are u talking about the labels of the plant with cortex, epidermis, root hair, apical meristem, and root cap</p>

<p>Yep that root hair absorbs and meristem constantly divides that was easy but about safety i thought for a moment cortex was cuticle so i put that in whatever</p>

<p>Eminence</p>

<p>yaay :slight_smile: thank youu
i thought i had that one wrong
and what about what affects population or smth
i circled A i guess
deer something i can;t even remember what word was there</p>

<p>I wish that was oxygen haha</p>

<p>And the food chain thing started with seeds and ended with snakes right?</p>

<p>about energy A 10% is transferred</p>

<p>So If i have like 70 raw what score should I expect</p>

<p>oh one more
about sperm
that was only tube closed right?
because semen has it’s own buffers to regulate pH as I can remember</p>

<p>@ Bluecholeric : I put the answer as “Epidermis” not cortex are you sure of the answer ? </p>

<p>The whole dear exp. :

  1. Carrying capacity : A. 1905-1910
  2. Explanation for significant decrease except : B. Resumption of hunting predators.
  3. Illustrated by the study : D. The size of deer population is dependent on predators.</p>

<p>The food chain started with seeds and ended with fleas, sorry dude I’m 100% positive :frowning: </p>

<p>Yes only 10% is transferred indeed.</p>

<p>Can’t remember the sperm one, be more specific ?</p>
