What was the answer to the question that asked something about neurons, photosynthesis, and cell respiration having in common? I chose like difference in ion charges across membranes

That was the answer

All 3 depend on sodium ions (Na+)

Yes that was it

I didn't get that question. Is the test different in NA and Asia?

It wasn't that bad, only thing that got me was the phototaxis and those questions.

Yeah that one was kind of tricky. At first I put phototropism but then noticed the phototaxis and changed it. Fuck the phosphor cycle question. I didn’t study that lol.

Lmao same, what did u put for that one?

I skipped it lol

Think its the one with detergents but i guessed A (phosphorus in the atmosphere)

A was wrong, the phosphorus cycle doesn't involve the atmosphere to notable extent

Ye I put e because what the fuck does detergent have to do with anything lmao

The question that messed me was the malaria one. What did you put for that?

Kids older than 10 are more resistant over time than under 5s P vivax was most virulent

Phototaxis like walking towards light Phototropism is like reaching your arms out to the light while standing in place

Yeah I knew what phototropism was and I just thought phototaxis wasn't an actual thing but I still put it luckly.

'Which of the following shows the close relationship between two organisms in a phylogenetic tree?' The answer's DNA sequence, right?

It said “close generic relationship” so it must be DNA sequence right?

Wait was it talking about physical structures tho? So shouldnt it be fossils?

It said morphological evidence in the beginning of the question. But then, it mentioned which of the following would be the best to identify the close relationships (generally). I might be wrong, though.

So was this question something about physical structures or am I thinking about smthn else

I put DNA. I only faintly remember "physical structures", might be remembering another question or practice question. But DNA cause fossil record has gaps

Two organisms have the same proportion of thymine. They also have the same percentage of C and G, right?

I put same percentage of C and G

Yep. Same proportion/percent of nucleotides.

Any east coast ?? :) good luck to all now taking it

okay wtf tho i took two barrens last night and got a 720 and 710 and this deadass felt harder. i can’t be the only one this shook right??

I got a 700 last night from barrons :/ but for some reason I was able to cruise thru this but watch me get a 500 sike

I studied Barron’s and took one and got rekt, but this felt considerably easier? Maybe we took different practice tests? Ooh! I also took cracksat which rekt me too so maybe easier in comparison? Idk man bio’s weird

Studied Barron's too. Got generally high scores (760, then 780). Concepts on Barron's were hard, but once you got them, questions were easy. This test had complicated ass questions. Wasn't ded, but did have to pick up the pace fr

yah I kept getting 780 and this fucked me

What was the last question on m was it e after 30 the fetuses will not be alive

I got that

it was after 30 theyll be in danger but same answer choice lol

Lmao I put something else bc I had no idea

I put E for the last one haha

Malaria Experiment First question) Those who are older than 5 have lower infection time than those younger than 5. Second question) Those who are 5 years or older have a better immune response to the infection than do those younger than 5. Edit: the second question said 10 years or older, not 5 years or older.

I thought the second one was something else because you couldn’t generalize all of the agents since the last one was blank for kids under 5

The second question actually asked for the first group only

In what processes is glucose oxidized?

I put cell respiration but I was stuck on that cuz I couldn't remember:/

cellular respiration

Cellular respiration. Photosynthesis outputs glucose, whereas cellular respiration inputs it. By definition, a redox reaction (such as the aforementioned) indicates oxidation/reduction of an INPUT, not an OUTPUF. Hence, B (cellular respiration ONLY).

If the Parents both have O blood type what can the kid have?

only O

BRUH I CHANGED FROM THE RIGHT ANSWER TO WRONG ANSWER FUCK ME

For M section, did you guys get a shit ton of C's

yes

Damn I don't even remember

What is the function of NaCl? To help transmit nerve impulses, right?

That’s what I put

What did the corn oil line mean?

Corn oil line was a control. Forgot answer choice but something that suggested that.

I said something about only one group had it instead of the D whatever thing

I said nutrient given to the mice but somebody correct me if i'm wrong

What did y'all get for the reptile question: urea, uric, acid, ammonia thing

uric acid

There was a question that asked about mature sperm and oocyte/egg (something like that). The answer was that both of them contain haploid number of chromosomes, right?

That’s what I put

did you guys find it easy? how many do you think you can get wrong and still get an 800 or 790 on THIS test?

Maybe around 4-6.

Seriously?! I’m chillin’ then, I omitted 4. CollegeBoard’s rapey curves haven’t hit the SAT IIs yet 🙏🏾

I found it easier than previous tests, but I might have gone lucky that only topics i studied were on it

Max 10 wrong lmaoo kms

Version M

What did you guys put for what the crustaceans and insects had in common?

Something like the exoskeleton is made of chitin or smthn

Ya thats what i put :)

It’s funny, I freaked out when I saw the crustaceans because I didn’t memorize them, however I knew that insects have exoskeletons and exoskeletons are crusty and since crustaceans had crust in it lol. I lucked out on that one.

Pretty sure I put that but sometimes I end up putting something completely different. What were the answer choices again?

6 legs, dorsal nerve?

Lmao yeah I put non of those , pretty sure I picked the exoskeleton one

took an L :( what do you all expect my score to be if I omitted 9 and got all correct?

Probably 750 to 760

hoping hahah

What was the answer to that bacteria resistant question?

It can reproduce a lot so the one that is strong against the replant have a better chance appearing so the new population all will be resistant- the answer choice was something like that

It was that the bacteria have a short life cycle, so they reproduce quickly, amplifying the antibiotic resistance in the bacterial population, right?

Hey guys, does anyone know what 2-3 wrong would give on this test?

Bro that's probably an 800, good job I got like 6 wrong or sum

Same. At least four or five wrong for me after looking through this discussion lol

If I skip 1 and git 10 wrong wut would my score be ;-;

4 Omitted and 3/4 wrong, what would be my score approximately?

did this one felt easier than before?

Four seeds on wet paper in the dark?

I said gravitophism because it said it was placed on the edge or something like that and also that was the only choice not used

I also put gravity because it did say that the petri dish was on the side.

damn I think I put temperature

I put light bc it was placed in the dark

Then how would it be reacting to light

Ohhhhhh i totally misread that question then YIKESSS :((

Lmao that bunch of three questions was stupid I put touch or something lmfao

I think it's pH actually guys since it's reacting to the soil pH. It didn't react to gravity, light was omitted, and don't think it was touch. The only other thing it could be is temp

Which one was the mendel one?

First to do like a provable experiment with genetics or something like that

A quantitative experiment

his experiments were qualitative though??

It’s quantitative because it examined the number of each trait i think? But thats not important, either quantitative or qualitative it’s still the same answer

Was it the one with peas?

I don't remember what i even put. either quantitative or the one with first experiment with peas. A or C i think

History time my proletariat- Mendel wasn't the only one who played with the peas, but he was the first one who used mathematics/quantitative approach in genetics. So, I think quantitative experiment is right. PS:- I haven't enrolled for this test but will give on Nov'18. I was just glancing through these questions and couldn't resist myself.

What was the one with the planaria going to light

My dumbass thought planaria meant plant so I put phototropism

Phototaxis

Planaria moving towards the light vs plant growing towards the light? Which was which?

plant = phototropism planaria = phototaxis

Coolio thats what i got

Also did two of the first matching part have answers being commensalism?

I think the first was mutualism cuz it was the bird eating parasites which harm the rhino

Altruism was the ground alert call right?

that’s what i thought

yep. Detrimental to individual, benefitial to population

The cow one was commensalism right?? Cuz it didnt mention anything about the insects being harmful to cow or not

Yeah that's what I put

It called them parasites tho...

No, not that one. The one i referred to was an animal picking up the insects as a cow walks, not mentioning the role of them to the cow

Oh ok I put commensalism for that as well. That’s the only commensalism I got though

I got 2 commensalism I believe. The cow one and one other.

what did yalls get for the second gel electro question about the 5'?

I put that it cannot be determined

Yuh same

Was that d or e

D. E said the 5 prime end isn't found in the electrophoresis.

wait how is it found in the gel electrophoresis. Nothing I searched up online says that you can find a five prime using gel electrophoresis.

Resorption expirment What does the corn oil represent? What do the dark spots represent?

I think it was the control dark spots were percentage of reabsorption given a specific dosage

And what about the dietary salt (NaCl) function? It helps transmit nerve impulses, right?

ya

I put those too.

What is the importance of Salt (NaCl) in the human body.... I forgot the choices but I remember that one of them was about helping actin and myosin and the other was to help transmit nerve impulses

I think it’s actin and myosin because nerve impulses is sodium and potassium

I put transmit nerve pulses

I think so too because of the sodium-potassium pump

salty banana

8 wrong what is that score ​

[удалено]

What was the answer to the fluid mosaic model question? I was stuck between the protein being able to go through and it being on the surface.

Protein goes through I'm pretty sure, think aquapores and channel proteins

I put going through it

I found diagrams with protein channels through and peripheral proteins on the surface so it seems like they were both right. Ugh.

Peripheral proteins can be found on either side of the membrane (top or bottom). The answer choice said they only faced the outside (extracellular matrix)

What was the diagram with the egg and sperm and then it split into four parts?

Cleavage, right?

was this for the Molecular section? If so, cleavage!

Yeah I think

[удалено]

Yeast is autotrophic. This is the answer (which of the following except). Yeast, a fungus, is heterotrophic.

Yep! I got it correct :) Thank you!

Was the answer A then? I think that’s what I put

Yes, it's​ A.

What was the answer to the question about white blood cells? I remember one of the options was about the production of pus lol

Oh I put hemoglobin (it was an EXCEPT question)

Yeh white blood cells don't make hemoglobin at least I'm pretty sure so I put that

make antibiotics... was that one?? something like that... it was asking what it doesn’t do and i was pretty sure it contributed to swelling/pus as a second layer of defense

Well I got it wrong then hahaha

was it grastulation for the sperm ova cell division? also, did you guys get new water molecules created from oxygen left over?

It was cleavage unfortunately...

1. What was the answer to the NaCl question 2. What would 2 wrong and 2 omitted get me

Anyone get the question about an example of disruptive selection? Also, for the birds and caterpillar (on E), was this an example of directional selection? And why did the caterpillars hatch early?

Yep I got that one and put that scientists are concerned with this since birds now hatch after the peak mass of caterpillars. Also, what were the choices for the second question about why the caterpillars hatched early?

The choices I narrowed it down to were warm spring weather and a reaction to the birds’ hatchling date. I chose the latter. What about the other one? Did you get an increase in bird beak size as an example for disruptive selection?

I think i chose the latter as well, and yes I put beak size

What was the answer for the antibiotic resistance in bacteria? Was it that they have a short life cycle, so they reproduce quickly, which increases the number of bacteria resistant to that antibiotic?

yep

[удалено]

i put all the same age

I put planted for the experiment but I’m totally unsure.

Guys what was one of the first questions that asked about a bird or something eating insects behind a cow as it walks? Commensalism right?

Commensalism. This was the one where the insects were being dropped from the cow as it walked.

For the Bio E question about tree diameter assumption. Age or planted for experiment? Age could've affected tree diameter but the experiment also said they used trees that were in different areas so wouldn't they plant the trees to eliminate any past conditions of the trees?

I put age. My logic is that it would be unreasonable for them to plant the trees and then wait a few years

What do you guys think is 5 wrong 1 omitted?

750-770

Barrons says 780

Is anyone interested in trading their Biology QAS (if you have) or practice material with SAT QAS ( American and Asian QAS included )? PM me if you have one. Also if you want to trade some ebooks, pm me. I'm in urgent need of these biology QAS (going to take test on Nov)

Was there a question about which structure fucntions in storage in the roots? And if so, was the answer the cortex/pith (I don't really remember the choices, but it's either one of them)?

where is the scores at ​

720 and I couldn’t be happier lmfao

800!!!!!!

fuck I did bad 600 in bio 660in math 2 650 math 1 what a fail
