<p>You can just tell by their previous offspring that it isn't 75% also AA, Aa, Aa, aa albinism recessive so 25% is what I put.</p>
<p>what was the answer to the question about the tight arrangement? Like what is the pattern for arrangement? Was it like homozygous?</p>
<p>it was homozygous for tight arrangement</p>
<p>no juicy is right</p>
<p>thats also what tipped me off</p>
<p>10% of energy is lost at ever level....definetely not most</p>
<p>so it has to be carnivores</p>
<p>On average, a 90% loss in energy between trophic levels. ... loss of energy leads to a substantial reduction in biomass between trophic levels. ...
so, you would have "Most" energy lost. Think about it..that's why you have so much less carnivores than herbivores and likewise more producers than herbivores. If it was only 10%, there wold be like thousands of animals, if there was such a small loss of energy.</p>
<p>then that question shouldnt be counted because the herbivores option was also 100% correct</p>
<p>it depends on how you look at it...</p>
<p>I was confused because there were two albino kids from the parents....so I got Aa x Aa and there was AA, Aa, Aa, and aa.... but since there were two albino kids I put Aa as the genotype.. but it was def wrong b/c albinism is recessive homozygous....but then again, there were 2 albino kids!? did I somehow misread the question? was the question actually referring to the parents on the right side of the tree?? or else i have clearly misunderstood genetics</p>
<p>idealist...albinoism is homozygous recessive so the only possible genotype for the parents could be Aa*Aa...even if three of the kids had it, it doesnt matter how many of the kids had it because it is all independently assorted. Do you understand?</p>
<p>who remembers the question about which fruit grew best or something on a clean medium...i put apple!</p>
<p>Reactionary...
UV rays was right. Insects, i.e. bees can see UV light
I guessed and put gamma rays grr....</p>
<p>so for the question about the ribose, phosphate group, and adenine, was that a nucleotide or RNA?</p>
<p>Nucleotide: A building block of DNA or RNA, consisting of ONE nitrogenous base, ONE phosphate molecule, and ONE sugar molecule (deoxyribose in DNA, ribose in RNA). (<a href="http://www.dphpc.ox.ac.uk/opcgg/glossary.htm%5B/url%5D">www.dphpc.ox.ac.uk/opcgg/glossary.htm</a>)</p>
<p>I'm pretty sure it's nucleotide...so I missed that question. I put RNA. Ugh, stupid! Sigh.</p>
<p>Oh, and also about the food web question, I'm leaning towards energy loss because even though it said food chain in the answer choice, food webs are made up of interconnected food chains. So it's still relevant, and in my opinion, the best answer choice...? :)</p>
<p>the answer is that most of the energy is lost.
even if that answer is iffy, the other choice that herbavores get more energy than carnivores is false- they get the same amount of energy, carnivores just have to eat more animals to stay alive.
i.e. i think we'd all agree that the amount of "energy" in a gazelle is the same as a cheetah or watever.</p>
<p>so can anyone approximate a grading scale for this test?</p>
<p>i think i MISSED (not skipped) at max 8, minimum 2</p>
<p>i think i may have mised 3</p>
<p>whoa....hopefully the curve is good</p>
<p>bannana_girl .... yea..... i see.... that was pretty stupid.... i assumed that since there were 4 offspring each had to be AA, Aa, Aa, and aa.... aahahha</p>
<p>I don't remember an apple question... do you mean the enzymes thing?</p>
<p>yeah it was the enzymes with the ph scale</p>
<p>that retrovirus one was weird...what was that?</p>
