<p>haha, well i just thought making a thread and studying together would be a good idea!
plus i have many questions to ask you all. :)</p>
<p>well i will start this study party with my question first. I really hope you guys participate a lot!</p>
<p>This question is from the real SAT biology test from College Board’s book (it’s called something like study guides for ALL SAT subject tests).
It’s #47. What i’m actually asking is if you guys could tell me what this problem meant.</p>
<li>According to the data, which of the following are initialy most successful in the succession taking place in the field described above?</li>
</ol>
<p>i just don’t understand the question.
Help???</p>
<p>Well, there are two types of succession. primary and secondary.
Primary is when you start without a topsoil
secondary is when it is just destroyed or abandoned</p>
<p>judging from your "field" description, its secondary.</p>
<p>because there is already has a topsoil, usually shrubs should grow best (sorry I don't have the book)</p>
<p>Q. Which of the following statements is true of most vitamins?
a. They catalyze the digestion of starches.
b. They have similar molecular structures.
c. They must be present in large amounts to be effective.
d. They cannot be synthesized by animals and therefore must be ingested.
e. All animals require the same vitamins.</p>
<p>The answer is supposed to be D, but i don't get it.
Is D the right answer, because "most vitamins" can't be synthesized by animals?
I know there are some vitamins that are synthesized by animals.</p>
<p>Another question!
Q. The largest population of omnivores can be supported if they secure their food predominantly from
a. primary producers
b. primary consumers
c. secondary consumers
d. decomposers
e. other omnivores</p>
<p>For the second one I want to say its A because if omnivores ate primary consumers, secondary consumers, or other omnivores they would essentilly be eating their own population. If you want the population to be as large as possible, then you want to eat the group that is outside of your population. Obviously, primary producers would supply more food than decomposers, so D is also incorrect.</p>
<p>The first one is correct by definition. A vitamin is a compound that is necessary for the survival of an organism, but cannot be produced in sufficient quantities by that organism to survive, so it must be obtained by a diet. Of course, small amounts of vitamins can be produced by the body, but for the most part, organisms must obtan vitamins from an outside source.</p>
<p>EDIT:: I'll be taking the Biology E test this month also :)</p>
<p>I think a more clear answer to your second question is because there are a lot more primary producers than anything else. In the animal pyramid, primary producers are at the bottom and they contain the most energy (10^7 kCal or something? not sure about that number). Every step up, the amount of energy drops by 90%. Primary consumers have a total energy of 10^6 kCal (again, not sure about that number but I am sure that each step up on the pyramid has 10% of the energy of the class under it).</p>
<p>Because the most energy is stored in the primary consumers, more omnivores can be sustained if they secure their food predominantly from them.</p>
<p>As for the "new" system of taxonomy (only really discussed in Barron's I think), I wouldn't worry too much about it. There was nothing on the december 08 test about it, and I feel as though the topic is too new for them to throw any stuff about the new "domains".</p>
<p>Do we have to memorize all the examples for plant types? like gymnosperms, angiosperms, etc...
cuz i think i memorized all of their characteristics, but i really don't want to memorize every single plant example. THat'd be really ridiculous!</p>

I memorized all the taxonomy of plants and animals. I know it's superfluous, but it's fun :P</p>
<p>I'm reading the PR now and next week i'm going to read an old McGraw Hill book. They're both pretty easy to read so far. Barron's did look really dry I must say.</p>
<p>Meh, I'd say Kaplan's is dryer than Barron's. PR is definitely the most friendly though. Infact, PR's book is actually so engaging that I could read through and study their biology book in a matter of 2 or 3 days.</p>
<p>Yes, if you can handle it and remember it. Barron's has, among other things, a good section on vitamins (if I remember correctly), for example. When I read PR two or three years ago, it was indeed a very smooth read. It didn't contain as much information as Barron's or Kaplan's, but it was fine for me as a supplement a day before the test, and it had a fairly good section on the nervous system. I don't know how it is now.</p>
<p>But Kaplan's really helped me out. It covered almost absolutely everything my test was on and didn't have too much extraneous information.</p>
<p>ya those questions that have paragraphs, explaining about an experiment. Then, there is a multiple number of follow up questions. These questions are ususally included in E/M section.</p>
<p>so is there any way i can prepare for those?
and i just got one more questions. Do core 60 questions have them too?</p>
