***OFFICIAL SAT BIO E/M OCTOBER 2014 THREAD***

Test Preparation SAT Subject Test Preparation
1

<p>New here but I decided to make a thread to discuss the Bio Test. I thought the test was pretty ok but some questions were difficult so I'm going to list the questions I remember. My answers are probably not right so please give me your input!!! </p>

<p>1 Amphibian- salamander
2 What was false about the chart (frequency)- the number of males and females were equal</p>

<p>3 Ethanol- OH
4 something with nucleotides: Phosphate group
5 One was the amino acid (NH2) </p>

<p>6 Cartilage- something with protein matrix (not sure)</p>

<p>7 The chart with the fetus and the mother (dont remember questions)</p>

<p>8 Hardy Weinberg: I put genetic drift but I'm not sure this is right</p>

<p>9The diagram with the plant (omitted)</p>

<p>10 Something with when you cut a dicot what is the result (omitted) it had to do with elongation and lateral growth</p>

<p>11 Father is autosomal dominant for a trait, mother doesn't have the trait. Father is homo for the traits- children will have the trait 100%
- I reasoned that the father was AA (homo) and the mother was aa because the trait would only need one dominant allele to show</p>

<p>There were 3 questions on the heart
12. order or circulation of the heart: started from i think 3 to 8-9 and then to somewhere out of the heart and then back into the heart
13. I forgot the question but I put structures 5 and 6 dont beat at the same time (prob not right)
14. </p>

<ol>
<li>Something about bile </li>
<li>where do starches break down - only in small intestine </li>
</ol>

<p>Forgot what they matched up to but something with:
17. mRna
18. tRna
19. rRna - ribosomes</p>

<ol>
<li>what does NOT show bilateral symmetry: jellyfish (they have radial symmetry)</li>
</ol>

<p>More chart questions with A B a and b
21. I remember choosing an answer based on the decline of the lines
22. </p>

<p>Lab Questions
23. Control was to see the dye amounts
24. Directly related because as time passed the dye continually decreased (might be wrong because it might mean they were inverse but I'm not sure/wasn't thinking right)
25. Question with the first 30 seconds and the last 30 seconds of the lab- the difference was greater in the first 30 seconds than the last</p>

<ol>
<li>Egg question: I & III </li>
</ol>

2

<p>i put NH2 for number 5 also, but do you remember what the question was?</p>

3

<p>@College4life I think the question was something regarding amino acids. I read from a textbook that NH2 has the compound “amino” in it so i put that</p>

4

<p>i think number 8 was random mating, i think i got 10 wrong ( i put that both would stop growing), for 15 i put it emulsifies fats. i think 16 is mouth and small intestine because amylase in the mouth breaks down starch also, </p>

5

<p>Cartilage: Connective tissue with protein matrix
Hardy Weinberg: Random mating
Fern Diagram: Sori</p>

<p>The rest I either don’t remember or agree.</p>

<p>Btw, mad cow disease is caused by prions. Am I the only one who had no idea? :confused: </p>

6

<p>@aphro24‌ did that question ask what was the acid part of an amino acid?</p>

7

<p>I thought the starch one asked where the enzymes from the pancreas acted on. I might be mistaken or gotten it wrong…</p>

8

<p>@Frigidcold‌ i thought the fern diagram was spores…</p>

9

<p>@College4life3 I dont remember the question to 8 but i know that some of the things that he did not want was random mating, natural selection, small population pool, mutations, and isolated population. The answer choices pretty much had all of these proponents so i just chose whatever was left
10. I completely skipped that one :stuck_out_tongue:
15. I think I put that too
16. In the Barrons book it specifically said that the pancreatic amalyse breaks down starch so I chose that one</p>

10

<p>A sorus is a cluster of structures producing and containing spores in plants and fungi, if I recall correctly. Maybe it is spores, idk.</p>

11

<p>Not plants, ferns specifically…</p>

12

<p>@Frigidcold I remember that question yeah it was prions. and can you explain the random mating part?</p>

13

<p>what was the purpose of the control in the dye experiment?</p>

14

<p>@College4life3 I think it was too see how much dye would leave the item being studied when being put under different lights </p>

15

<p>In Kaplan it says that for the Hady-Weinberg equilibrium to be maintained there needs to be a large population, no net mutations, no migration, and random mating</p>

16

<p>@aphro24‌ so was it to see how the light had an effect on the dye</p>

17

<p>Probably going to cancel scores anyways, was shooting for 800, probably got 760-770. :/</p>

18

<p>Links get the thread closed… >.></p>

19

<p>@Frigidcold‌ isnt a 760-770 good though</p>

20

<p>@College4life i think so my memory is a bit hazy though</p>

<p>Does anyone remember a question with phylogenic something? I put homologous structures but I completely guessed on that one</p>

<p>I thought the last 20 questions for the M sections was pretty ok.

  • there were two question on DNA sequence for example (CGA -> GCT) </p>
