<p>The first question about fossils? I remember one question asking for origins of life on earth. the answer to that was A (amino acids experiment.)</p>
<p>uric acid was reptiles (which includes birds), so Mr. T-Rex and birdie.</p>
<p>huh, it’s strange that people argued the primate question. whales are mammals!</p>
<p>I literally missed all of the questions about the eye diagram. Never learned that stuff D:</p>
<p>what about how sexual reproduction is favorable for natural selection. was it that it allows for a variation in phenotype or that it has few mutations?</p>
<p>FROM 2010 with some minor corrections.</p>
<p>Bio M
Compiled List (not in order):</p>
<p>1,2 - Mitochondria
3,4 - chloroplast/cell membrane
Eye - retina, lens, and ciliary muscles
Horse/Donkey → Mule = hybrid
Yeast reproduction - asexual reproduction
some other reproduction scenario…
Genetic variance of sexual reproduction - crossing-over and recombination
Prokaryotes/Eukaryotes share which organelle - ribosomes
Plant drawing - palisade mesophyll (site of phoyosynth.), Stomata, and vasucalr bundle
Not part of arthropods - leeches
Catss/Dogs same class - same phylum
Plant research - during day produces more O2
Which of the following is true - O2 is by-product of photosynthesis
19. Darwin’s natural selection is most evident in <em>populations</em>
Estrogen - I, II, and III
Implantation of embryo location - Uterus
Clumped population - competition or ans. choice C
Allele frequency would be least affected by <em>random mating</em>. You have to realize that the other choices are violations of the HWP
Genetics - 3:1 ratio, so Bb x Bb
Genetics - 100 % of purple will be Bb
Lichen - could be a mutualist/parasite but best answer is probably <em>mutualist</em>
Order of fossil evidence - Starfish, shark, dinosaur, bird
Primates - most closely related to primates
Convergent evolution - whale and shark since they are derived from same ancestor
Enzyme - most denatured at 100 degrees centigrade
Least likely blood type of child - Type O
ABO types - agglutination rxns according to what im hearing, but might be hemoglobin structure
Most diverse biome - Temp. Decid. Forest since coral reef is not a biome, but rather an ecosystem. The ev. for coral reef is also just not sufficient. The article doesn’t even mention the word biome once.?I put coral reef…
Tundra - can’t grow deeproots
Energy from phytoplankton to third trophic level - 10% → 1% → <em>.1%</em>
Bicarbonate ions in the <em>blood</em> - carry carbon
Cell division order - begins w/ interphase (undifferentiable chromosomes) and end with two cells undergoing division again (cell plate fragmented slightly)
Cell divison - Plant since cell plate
Chromosome attached at one end - ans. choice e, i think?
Vine data - confirms hypothesis
Vine graph - the control grew more steeply than vine
Mice Litter - 85/120 = 80%,
Mice Litter - delayed birth → death
Mice :Litter - same food
Bacterial Protein Synth. Drawing - Ribosome was 6
Bacterial Protein Synth. Drawing - hydrogen bonds were 2
Bacterial Protein Synth. Drawing - mRNA was 5
Muscle - electrochemical signal so either electrical or chemical. IMO it’s electrical because an action potential is always electrical
Changes in environment detected first by - Nervous system
ATP - hydrolysis to ADP + i stimulates myosin head
Amino Acid drawing - Amino Acid
peptide bond would occur - @ 2 i believe since it has a nitrogen that is only bonded to carbon
By-product - CO2 (C and double bonded O)
Highest rate of photosynthesis - violet
Aquatic algae - low amount of chlorophyll is best ans. since it assumes the least.
Semipermeable membrane - H20 flows back and forth
Stained DNA - Chromosomes bolded</p>
<p>It was the recombination that gives new phenotypes</p>
<p>No wrong ones yet!! :D</p>
<p>^me neither since ap bio doesn’t need it. I left one blank, but almost put down my guess for the iris (which was right) :c</p>
<p>lichens are parasites</p>
<p>There are a couple of wrong ones in that big list guys</p>
<p>YES!!! i got the estrogen one right total guess haha</p>
<p>and doesnt the retina contain photoreceptor cells?</p>
<p>@wharton lichens are a mutualistic relationship between i think fungi and bacteria? but they’re definitely mutualistic</p>
<p>disagree with clumped popul problem.
[Species</a> distribution - Wikipedia, the free encyclopedia](<a href=“Species distribution - Wikipedia”>Species distribution - Wikipedia)
I put A, for mates</p>
<p>actually, disagree with the entire list… sooooo many things wrong! so outrageously wrong I’m quitting this thread… bye!</p>
<p>beexx93 that sucks, i took it after taking honors bio, and i was happy with a 700. my friend got a 740 though so it’s not unreasonable to to okay.
there’s no sat ii for euro though</p>
<p>i thought the answer to the bicarbonate ion was to act as a buffer because Barron’s said it is the most important buffer in the blood</p>
<p>Lichens are mutalistic DEF.</p>
<p>“Lichens are ‘dual organisms.’ Every lichen is a partnership between members of two different kingdoms which live together in a special, mutually beneficial relationship (a symbiosis).”</p>
<p>Clumped population - competition or ans. choice C
NO!! It asked why clumped population occurs and it’s because of the mating probabilities</p>
<p>Lichen is mutualistic between fungi and photosynthetic bacteria or algae</p>
<p>ABO types - agglutination rxns according to what im hearing, but might be hemoglobin
structure
Is hemoglobin because it has nothing to do with ABO. Agglutination does because of the antibodies…</p>
<p>Most diverse biome - Temp. Decid. Forest since coral reef is not a biome, but rather an ecosystem. The ev. for coral reef is also just not sufficient. The article doesn’t even mention the word biome once.?I put coral reef…
It’s coral reefs. Temp Decid is not that diverse, tropical rainforests and coral reefs are the 2 most diverse and since tropical wasnt there…</p>
<p>Vine data - confirms hypothesis
It proves the hypothesis wrong actually</p>
<p>Muscle - electrochemical signal so either electrical or chemical. IMO it’s electrical because an action potential is always electrical
It’s always chemical because electrical occurs in gap nexus and you have a gap in the muscle structure. Plus it’s acetilcoline which is a neurotransmiser</p>
<p>Aquatic algae - low amount of chlorophyll is best ans. since it assumes the least.
Actually when you are deep in the water, you need MORE chlorophyl. The only plausible one was the oxygen bacteria. The PH is slightly true but it said significantly and thats not true.</p>
<p>Trust me guys, I went to the International Biology Olympiad, this was a piece of cake :)</p>
<p>i thought the ribosome was 5</p>
<p>Forgot the one about the HCO3-
It acts as a buffer. It also carries CO2 but not TO the cell but FROM it</p>
<p>"The hemoglobin inside the red cells of a person with type O blood and that inside the red cells of a person with type A blood are identical. " (provided no mutations and stuff and whatnot)</p>
<p>CORRECTION: it’s hemoglobin structure.</p>
<p>^ agree with kili16 on the buffer one :)</p>
<p>@kili16</p>
<p>them neuron to muscle was chemical because an axon carries an electrical signal but it sends a chemical signal across the gap known as a synaptic cleft onto receptors on the muscle cell</p>
<p>guys feel free to edit that list asyou like</p>
<p>If you have High cholesterol, you are at risk of atherosclerosis.
Does anyone know the answer to the cheetah question?</p>
