    D ADH increases reabsorption of water in the collecting duct so no less ADH = less reabsorption = diluted urine

    1) High levels of estrogen will...
    a) Induce the hypothalamus to secrete GnRH
    b) Inhibit ovulation-could be this too i think?
    c) Induce FSH production-
    d) Form the corpus luteum because high level of estrogen will cuase a surge in LH which is followed by sharp decrease in estrogen and forms the corpus luteum

    2) Which molecule is stored in the vacuoles of plants that can undergo CAM photosynthesis?
    a) glucose
    b) sucrose
    c) Malic Acid only thing i remem bout CAM photosyn is that it assoc with Malic Acid but i thought taht CO2 is uptaken at night and CONVERTED to Malic acid...so if this is the answer its not a molecule stored in the vacuoles of plants but it is what CO2 is converted to. so something else is prally the answer im assuming
    d) Formic Acid
    e) Absisic Acid

    3) Has protonephridia and bilaterial symmetry; you would classify this as:
    a) Roundworm
    b) flatworm
    c) echinoderm
    d) Rotifera
    e) Annelida?

    4) Where does CO2 couple with Rubisco in C4 plants?
    a) Bunndle Root cell
    b) Bundle Sheath Cell
    c) Mesophyll Cell
    d) Pallisade
    e) Meristematic Mesophyll

    5) A decrease in ADH vasoppresin would cause all of the following except?
    a) Diabetes insepidus
    b) Low blood pressure
    c) High Blood pressure i think increased alsosterone or ADH would cause this
    d) Diluted urine
    e) All of the above

    Dude you are going way way overboard. Honestly your time would be spent better studying more variety of all sections than these details.

    Who says I havent...my theory is if you know everything to its detail then you know everything from the surface...

    For example:
    The first question about the menstraul cycle, you have to know the whole process in order to understand the question in its entirety, i made the questions that way...it makes you think of the whole process as a whole. Obviously things questions like this will not pop up on the exam but if you can understand every process to detail then you will figure answers out easy...And btw no one has gotten the first question correct...probably because they are missing the detail involved to answer the question. This is on the level of destroyer, were there questions on the real exam like destroyer, prob not but did it teach you things...for sure it did. thanks

    2) Which molecule is stored in the vacuoles of plants that can undergo CAM photosynthesis?
    a) glucose
    b) sucrose
    c) Malic Acid (I have no clue on this one, I need to brush up on photosynthesis)
    d) Formic Acid
    e) Absisic Acid

    3) Has protonephridia and bilaterial symmetry; you would classify this as:
    a) Roundworm
    b) flatworm
    c) echinoderm
    d) Rotifera
    e) Annelida ( I know earthworms have nephridia and bilateral symmetry, but idk.....protonephridia?? sounds like an embryonic form?)

    4) Where does CO2 couple with Rubisco in C4 plants?
    a) Bunndle Root cell
    b) Bundle Sheath Cell (isnt a Cactus a good example of a C4 plant?)
    c) Mesophyll Cell
    d) Pallisade
    e) Meristematic Mesophyll

    5) A decrease in ADH vasoppresin would cause all of the following except?
    a) Diabetes insepidus
    b) Low blood pressure
    c) High Blood pressure
    d) Diluted urine (i'm going with this one due to the pact that decreasing ADH decreases the permeability of the collecting duct........but wouldn't it to some extent effect Na+ absorbtion..which would effect blood pressure?)
    e) All of the above

    Wow, good test man. I'm curious now.......and can't fall asleep.

    Are you kidding?? Your tests are great, b/c people share info even when we get the answers right, and if we don't know them, we are encouraged to study harder for bio. I was planning on a "bio-day" tomorrow anyway, but now i'm pumped to dig into Schaums!

    The two of you who put (D) for #5 misread the question. It says it would cause all EXCEPT for which one.

    question number 1

    shouldn't you have to mention high level of estrogen IN THE BLOOD in the question? just my thought.

    Thanks for the answers! damn i gotta go study some more menstruation.

    I am only good at calculating the dates when you don't have to use condoms. but thanks.

    ahh! #1 is tricky!! See I thought we are already in the menstrual cycle. So if we have high levels of estrogen, which means we are in ovulation phase. So I was thinking answer choice d, which is the next step after ovulation. Nice!!

    when i woke up, i thouhgt about question number 1 and i think the question itself was oriented to be treaky. (if that make sense to you guys, sometimes I write stuff that does not make sense grammarically = international student) anyways alright, let me ask you a question regarding number 1 again.

    question says

    1) High levels of estrogen will...
    a) Induce the hypothalamus to secrete GnRH
    b) Inhibit ovulation
    c) Induce FSH production
    d) Form the corpus luteum

    in order to get this question right, you have to think critical. I see how osimsDDS presented his reasons, but let me ask you a question.

    1. the question itself does not give enough information to think correct.
    mentrual cycle has two phases, follical phase and luteal phase. and both phases have relatively high concentration of estrogen. If the question was asking if you have high estrogen concentration during follical phase, which means high estrogen concentration triggers positive feed back to hypothalamus which secretes GnRH to produce more estrogen. and when the estrogen reached certain amount, you get midsurge of LH and ovulation happens.

    2. IF the question was asking high estrogen during luteal phase or after ovulation. the corpus luteum produces both progestreron and estrogen which trigger negative feedback back to anterior pituitary to stop produce FSH and LH. and this inhibits further ovulation right after you ovulate an egg. IF the question meant higher concentration of estrogen than progestron which only happens if the patient has cancer which inhibits hormon production. but i don't think he did, the concept is too hard for DAT.

    few options with different answers.

    if high concentration of estrogen and progestron, then what happens?
    then the answer should be B.

    if you have high estrogen in the follical phase, then?
    then the answer should be A

    if you have high progestron anytime, then
    the answer should be always inhibiting ovulation

    My thought is that when you only have high estrogen and low progestron, it will only promote ovulation b/c of positive feedback. however, if you have high estrogen and progestron, this will inhibit ovulation

    please correct me if i am wrong. i wrote in hurry cause i gotta go work, but really good college-level question.
    see you!

    I just wanted to mention again that these questions that osims has been putting up were very helpful. I took my DAT yesterday and there were some very relevant and informative topics discussed in these threads that proved helpful on test day.

    Osimsdds, keep on posting. Good job. I got all the answers right [before checking it with your solution]. I wonder how people can say 'a' for first question, or anything except high blood pressure for the last question. I got lucky on the flatworm though. I was not sure about that one.

    harrygt,


    the first question is so vague, but if i was to answer that exact question on the test then i would put answer A.

    i explained my reasoning up there
