<p>for that i said haploid gametes also, but i idk.</p>
<p>any1 know what the curve is going to look like?</p>
<p>um i put enclosed circulatory systems, lungs and binocular view? think</p>
<p>yeah thats what i said</p>
<p>i also said that-b.c that was the only one with lungs-which would be necessary to move on land</p>
<p>i thought it would be backbone waterproof skin and teeth</p>
<p>support, water retention, and food</p>
<p>I think I put a for that one! dammit…</p>
<p>how the heck does the Bio 2 have such a hard grading scale…if you miss like 2 you can’t get a 800.</p>
<p>From what I can tell, this test was pretty tough.</p>
<p>why waterproof skin? also i beleive many fish have backbones-so that wouldn’t be a necessity, would it? wow i hope im not wrong lol</p>
<p>This. Was. Scary. </p>
<p>Didn’t answer eight questions, got three wrong according to this thread, and I am very, very disappointed in myself. </p>
<p>Oh worse-than-mediocre score, I don’t wish to suffer your embrace. :(</p>
<p>i put the backbone choice for that one.</p>
<p>i think the enclosed circulatory system is the main part, because the atmosphere would lack gases need to breath.</p>
<p>Time to compile answers! I didn’t think the test was too bad (Bio M)</p>
<p>-water separation: lipids
-insulin (secretory granule)
-graph supported the route the radioactive substances traced
-graph showed how it goes from rer to golgi to vesicles
-right atrium, right ventricle, lungs, left atrium, left ventricle, aorta
-most diversity: island A
-least extinction: island A
-least immigration: island C
-two germ layers: hydra and jellyfish (I and III)
-scar on tree: .9
-ribose, phosphate, nitrogenous base: RNA (ribose is only in rna, dna has dioxyribose)
-polygenic tree: dietary needs
-earthworm diagram: the three involved in segment I, the three involved in segment II, stimuli from segment III would not cause muscle contraction in segment I
-controls: temp and light
-lymph: interstitial fluid
-dialysis experiment, it was NOT isotonic, osmosis could have been incomplete at end of 24 hrs so answer was I only
-blastocyst in uterus
-fertilization in oviduct
-gametogenesis in the ovaries (gametogenesis occurs at birth for males, only for females does it START at puberty)
-necessary for sexual rep: two haploid (no centrioles in plants)
-allele: related proteins
-the one with the “what made it necessary to move onto land” answer choice was A.*</p>
<p>Gud work lollypop7218!</p>
<p>for the last one u have was A with lungs?
(i thought the lungs would be absolutely essential. (amphibians have them and they were the first animals to move to land-so i think they were the transition step b/c they also have gills)).</p>
<p>and also wat was the I ans choice for the dialysis bag-i dont rem? haha</p>
<p>for that question I put lungs, amniotic egg, and kidneys</p>
<p>lollypop7218
“-ribose, phosphate, nitrogenous base: RNA (ribose is only in rna, dna has dioxyribose)”
Coudnt it also be a nucleotide? becuase a nuclotide has a sugar, phosphate, and a base. RNA is a chain of nucleotides</p>
<p>Nope, plant cells don’t have centrioles.</p>
<p>i dont think nucleotide was an ans choice for that one-i think it was for a diff one. also i think lollypop7218 has gametogenesis in male/female mixed up. For males it starts at puberty-females are born with all the eggs they will ever have. So idk wat the ans to that is (i just went with epididimys).
Can someone tell me what answer A included for the movement to land one. and wat ans I only included for the dialysis bag pls?</p>
<p>Hydra and Jellyfish is right, just the numbers should be II and IV</p>
<p>It was definitely nucleotide. I had RNA at first, except that had the word “one” bolded and underlined before each of the components.</p>
<p>Also, the control one isn’t definite since they had weird wording so we really don’t know what they meant.</p>
<p>If the question was specifying only ONE of a ribose, ONE of a nitrogenous base, etc., then it was a nucleotide. RNA is a string of nucleotides.
And jayjay12077, I also put the same answer as you for land adaptions.</p>
