**OFFICIAL SAT Biology E/M June 2013 Exam**

<p>i think cell wall-plants animal and fungi</p>

<p>Does anyone remember which one #27 was? I skipped it and have a feeling it was the one about histamine, pus, etc</p>

<p>what was graph for beetle?</p>

<p>post answers to the hypertonic hypotonic and isotonic…</p>

<p>viruses are way smaller than cells, so the electron microscope is needed</p>

<p>what u guys expect for the curve?</p>

<p>plants, animals, and fungi was definitely mitochondria.</p>

<p>The beetle one, I put the one that went up quickly, then hit carrying capacity, I wasn’t too sure about that one though</p>

<p>hypotonic, etc, solutions: the first one was cell 2 (animal cell in isotonic solution), then cell 3 (animal cell in hypertonic solution), then cell 4 (plant cell in hypotonic solution) (I think so)</p>

<p>for the brown yellow one, I put randomly mate a whole group because if you only mate two animals once there is a slim chance that the allele you desire will show up. is that right or?</p>

<p>Some answers I know for sure are:
Transmission Electron Microscope (for viruses)
Xylem is dead
Turtle is reptile
Frogs breathe through skin
Apical Meristem=Growth
Phosphates are in RNA
I had some questions too. Can anyone confirm/deny</p>

<p>ADH increases reabsorption of water
The question with the plant taking vitamins from the other plant was parasitic
The difference between genomes was due to a DNA replication error
The female was yellow and the male was brown
6-24 hours
Which is true about menstruation? The endometrium lining is shed when it is not fertilized</p>

<p>@teenuh
I don’t think that’s correct, because randomly mating animals will give you random, meaningless results. The results can only be useful if you know where they came from and what alleles produced them</p>

<p>brooke321: adh is reabsorption in collecting duct, and yeah parasitic, I put dna replication error (idk if its right), female male I put different, yeah 6-24 hours, and for menstruation I put something else, I think it was the ovary stimulates the uterus or something like that</p>

<p>brooke321: ugh yeah I see what you’re saying. :’(</p>

<p>plasma contains???</p>

<p>aw it’s okay :slight_smile: Only one question!
For the ADH one, did you remember if it specifically said reabsorption of water? I don’t remember if the answer I put mentioned collecting ducts or not.</p>

<p>Wasn’t the beetle one was a type 3 survivorship curve?</p>

<p>hmmm… it probably did say “of water” I don’t remember, but yeah I remember it saying collecting ducts, unless my memory is tricking me.</p>

<p>@medical boy yeah.</p>

<p>hmm, @medicalboy, I think the question asked about the population, not the survivorship curves for the individual organisms</p>

<p>@YaleHopeful:</p>

<p>plasma does not contain exocrine secretions (saliva)</p>

<p>@satman1111 but didn’t it say that a lot of them died out very young, so the graph would look like a survivorship 3 curve…</p>

<p>and the menstruation one was the endometrium answer. Although there is feedback between the ovary and uterus, menstruation involves feeback between the ovaries, uterus AND the pituatary gland</p>
