low 700</p>

<p>@airplane im pretty sure the curve is huge this year, especially for E
like *** @ the clam and miller urey experiment</p>

<p>does anyone plan to make a compiled list ;)</p>

<p>anyone remember anything else?</p>

<p>For the one with the protein+ protein </p>

<p>was the answer dehydration synthesis?</p>

<p>I would think after burning down lichens would grow…</p>

<p>@dancingbear: protein + protein: you are correct</p>

<p>was the oak tree and the tree chart in the ecology section? anyone remember anything else from these?</p>

<p>oh ur right, i suck at ecology</p>

<p>@waterbottle: no, it was part of core ?'s, it was somewhat confusing</p>

<p>one asnwer was mutation?
another was compitition?
and another was takeing out trees had no affect?</p>

<p>I agree with everything above.</p>

<p>The farm question was bean and rice, because it’s at the bottom of the ecology chain. Raising primary consumers loses 90% of the energy put in to raise the animals.</p>

<p>Went back through the thread and tried to consolidate all the answers:</p>

<ul>
<li>Needs confirmation
** Unanswered</li>
</ul>

<p>Mother does NOT use placenta to send nerve impulses to the infant.
Cow/Bull question (unwanted recessive allele): Rancher was cheated.

  • Huntington’s disease: 50%
  • Characteristic of blue-green algae: reproduce by fission
    Rh factor: 50% chance
    Rats are most closely related to monkeys (of the choices given).
    Contaminated ground beef/bacteria: I, II, and III
    Chickens are most closely related to reptiles.
    Urine/glomerulus filter/glucose content: Glucose is absorbed back into the bloodstream.
    Caffeine inhibits the antidiuretic hormone, so it causes a larger volume of dilute urine.
  • Somatic cells and exocytosis: A pancreas cell when it excretes enzymes.
    FSH is produced by the pituitary gland.
    Middle part of the chromosome is a centromere.
    A chromosome contains 2 DNA molecules.
    Chromosomes can be seen during mitotic metaphase.
    Thyroid gland affects metabolism.
    Kreb’s Cycle takes place in mitochondria.
    Cell placed in petri dish with high calcium concentration, calcium is moving outwards: active transport.
    Sperm production: 4 haploid
    Amylase is produced by the salivary glands and pancreas.
    Stomach produces pepsin.
    Pancrease secrete lipase (fat digestion) and trypsin (protein).
    RBC’s transport oxygen.
    More white blood cells present when there are foreign bodies present (can’t remember exact phrasing).
    ** Hardwood forest burns down; a year later, what types of plants are present?
  • Humans/behavior: Reasoning
  • White-eyed fruit fly in a family with generations of red-eyed fruit flies is an example of a new mutation.
    White guinea pig and black guinea pig mating: Dominance
    White flower + red flower: Incomplete dominance
    ** Which is least important in classifying organisms? (Absence of internal body cavity/symmetry/embryonic development pattern/something about genetic similarity/??)
    Secondary structure of proteins is held together by hydrogen bonds.
  • Plant with a genome of 50,000? Answer was 50,000 RNA transcriptions?
    Dehydration synthesis
    ** “All living organisms”/respiration: answers included something about specialized structures (gills/lungs), and pure oxygen…</p>

<p>I added what I remember, but some of them I’m not sure on…</p>

<p>Any ideas as to what -4 and 2 omitted will be for bio m?</p>

<p>i got the cynobacteria (blue-green alea) was no memebrane bound nuclues</p>

<p>Thanks for the list!!!</p>

<p>Cyanobacteria: no membrane-bound nucleus
Gas exchange: must have a moist membrane</p>

<p>@wander yes i got the moist membrane as well.</p>

<ul>
<li>Humans/behavior: Reasoning</li>
<li>White-eyed fruit fly in a family with generations of red-eyed fruit flies is an example of a new mutation.</li>
</ul>

<p>confirm these two.</p>

<p>The exocytosis one was my answer, but i’m positive about, the AP biology textbook says it</p>

<p>Im positive about the exocytosis human/behavior is right and i put alleles for the white-eyed fruit fly question.</p>

<p>gas exhange: umm i got something else, anyone remeber answer choices</p>

<p>@DancinggBear: i dont think it was new mutation, it was something else (might have been alleles, i forgot)</p>

<p>I think rats are most closely related to squirrels? they are BOTH in the rodent family</p>

<p>“Bryophates are primitive plants that lack vascular tissue. they must live in moist environments…” from Barrons SAT II bio</p>

<p>edit: water, biochem of rats + humans are about the same, and biochem of monkeys + humans are the same therefore biochem of rats and monkey are the same… it think</p>

<p>@jjtheairplane; for the gas exchange one i got lungs/gills not sure about the other ones sorry</p>
