<p>^^^^nitrogen is correct</p>

<p>wait, i’m confused because huntington’s is autosomal DOMINANT. so it was definitely parents 5 and 6, and 50%? </p>

<p>I don’t remember what the questions were exactly.</p>

<p>What did people put for the acid rain 10^-4 one???</p>

<p>Verdict on which biome produces the most food for humans?</p>

<p>skunks are omivores?</p>

<p>Yes both correct ichiruki.</p>

<p>And yes skunks are omnivores.</p>

<p>Biome base don google searching was grasslands.</p>

<p>Acid rain was 4.</p>

<p>I got angry when I didn’t see marine for the food biome question. I guessed grasslands instead. Whats the answer?</p>

<p>Ok. I’m getting the genetics questions confused i think. Tehre was one that i got 0% on and there was another i got 50% on.</p>

<p>Acid rain was 4</p>

<p>you couldve just got it because all the other ones didnt make sense. it was like 10,000, -4, .00001[wayyyy too acidic] on a pH scale of 0-14.</p>

<p>and if you like math then pH = -log[H+]
pH = -log 10^-4
pH = -(-4)
pH = 4</p>

<p>yeah i have no idea for the most food biome one, i was deciding between deciduous forest and grassland and ultimately chose grassland because I was thinking about the Great Plains… but I’m like 95% sure that that’s wrong</p>

<p>i skipped the acid rain one and left it blank
for most food i had put rainforest but im not sure
and yes i put skunks are omnivores</p>

<p>^^^Yes there was one that was 0% perhaps you are getting confused.</p>

<p>id say the tropica rainforest i</p>

<p>one was epidermis nephrons, neurons? Then for the tomato one it was virus? And for the one about why plants can live on land now its because of the waxy layer? Trophic Level Sheep/Wolf? </p>

<p>No teeth for birds?</p>

<p>yeah, i still believe tropical rainforest as well. it has the most diversity of plants and animals…</p>

<p>yeah huntigntons is autosomal dominant</p>

<p>ok so i know i got the one about the peat bog wrong, i got the one about the fertilizer wrong because i put minerals for that one and i got the one about the angiosperms and gymnosperms and im so mad because i put down seeds first and then chazgne d it to influorescence</p>

<p>i put 5 and 6 but now i don’t understand why. they were both unaffected, so how could they pass on a autosomal dominant to a child when they themselves don’t express it?</p>

<p>if huntingtons is dominant and father had it, but the mother’s family showed no history, then the children have 50% chance of getting it</p>

<p>^^
it was recessive not dominant (pedigree)</p>
