What did you guys think about it?

Charlie Brown

Moderate difficulty. I thought the more knowledge based questions were easier and the labs were slightly difficult. What about you?

jakeiscool

yea it was kinda diff form what i expected
for those who did M, what did you guys get for the gene chart one (rRNA, G6P, etc)
i put rRNA twice (two questions)
one was about which one shows the least divergence and other other abt distinguishing between bacteria vs plant vs animal?

cloisville

i barely had time to answer those questions...

i think for the question about distinguishing btwn plant/animal/bacteria, i put down whichever locus had the biggest range between each species. so it went like 0, 0, 16, 38, 52. i think?

jakeiscool

^^^ what was ure reasoning behind it? i kinda didnt understand the chart loll what did others say.
also what did you say for they very last question. I said choice C (they are diff from humans and could possibly be diff from each other?)

cloisville

i'm not even sure my answer was right. but... i think they wanted you to know that the other genes didn't necessarily indicate differences between ALL the species. like the other genes had 0 (human 1), 0 (chicken), 16 (fly), 48 (corn), 48 (e. coli). or something like that. so if you added a new species that had 48, you wouldn't know whether to put it with corn or e. coli.

for the last question, i put C too.

jakeiscool

hmm i put rRNA cuz it was 0 for all animals, 6 for corn (a plant) and 18 for ecoli (a bacteria). but liek you i dunno if thats right
at least we both got C for the last one

Tinks800

i thought it was pretty easy, just got stuck on like a few questions but over all, not too hard.

jakeiscool

which ones were u stuck on?

Tinks800

hmm i cant remember exactly...
but i only left four blank and im confident i didnt many wrong
hopefully enough for over 750 atleast

Charlie Brown

I was confused about a few of the questions. Does anyone remember the ones about measuring solutes or something (one of the answers was olfactory glands)? What about the description of the organism (3 germs layers, bilateral symmetry, etc.)?

jakeiscool

yea it was chordates and olfactory/saliva glands
what did you guys say for population density. Was it countig all the species in one sq mile and extrapolate?
how about the darwan q about which one is true? i chose the "slight variations affect who wil produce offspring (sumthing liek that)

Tinks800

yes that was taste buds and olfactory hairs or something
and that was chordata, it mentioned something about a notochord

Tinks800

yeah the mark and recapture technique for population density question

Charlie Brown

That's what I said (count all the species in one sq mile and extrapolate). Do you guys remember the lab questions on the common questions (1-60, not each additional 20 question section)? The one about the DNA or the aquarium and oxygen one?
