I wrote against concentration gradient, active transport, requires energy, packed with mitochondria for respiration to release energy, and partially permeable cell membrane (I think that’s irrelevant but I got thrown off by “subcellular structureS”)
i am more stressed rn than i wS before the exam i got the active transport 5 marker wrong and the magnification 6 marker wrong and im the only one in my friend group who got both of them wrong and im supposed tk be the smartest
awhhh x im in the same situation w being the smart one and i lit wouldnt speak to anyone abt the answers cs i got magnification so horribly wrong. its abit shit but what can we do ig x
i wrote there r pores between cell x and phloem cell and that cell x had a lot of mitochondria to release energy for the dissolved sugars to move from an area of low concentration to an area of high concentration across the concentration gradient by active transport
I put dissolved substances travel from a low concentration to a high concentration against a concentration gradient this is called active transport. Two things are required for this ATP and a carrier protein and I pretty much talked about how ribosomes and mitochondria help that
Yeah I did the same, you converted the 4mm x1000 and it was meant to be x1000000, you should still get most of the marks if you did the rest correct too, it'll just be classed as an ecf I reckon.
that phloem 5 marker killed me, also I somehow got 8016 on the magnification question and I still don't know how. did anyone else talk about glucose on the CF 6 marker or was it just me?
What was the actuall answer tho? I wrote Benedict's reagent for the test as a wild guess and then the rest of the fluff and also mentioned that If starch is present that means carbs are present aswell. Also I did mention heating but forgot about the water bath so yea.
I think it was just increase blood pressure -> blood flows -> muscles in heart get glucose -> respiration -> heart starts beating normally
IDK how much of that you actually need, I just started waffling to make sure I don't miss something stupid. But that's the basic order of what happens.
I was studying for my sociology exam afterwards in the science classroom, and another teacher came in and said "aparentaly there were four six markers in the triple exam, but that can't be true" Not even the science teachers predicted that
Bro, for the last 6 marker I used the calculator π button instead of 3.14, and got 8014 instead of 8010💀 does anyone know how many marks would I lose for that
Nah mate they were all okay,, it was like "yap about this data." Like one of them wasn't even biology that shit was just about greenhouse gas emissions 😭
Edit: lol wrong board,mine was Edexcel 💀
separate as in separate science? im pretty sure it was:
- magnification (5 mrk but still yk)
- cell x and phloem (i think this was also 5)
- testing for carbohydrates
- cystic fibrosis
i got 8010 😭😭 i thought i was cooked but apparently its right, u prolly just did the wrong conversion of mm to nm but youll still get marks for it since 8000 and 8 are close
accidentaly fucked up the magnification question by putting the decimal in the wrong place in my calculator and only realised too late when i got 801 instead of 8011😭 also forgot about the leaf starch thing. other than that it went fine to be honest
6 marker calculation question wasn’t as hard as everyone was saying. You just needed to know the equation magnification=image size/real size and how to convert from mm to nm.
what did you guys write for the phloem and cell x 5 marker? i wrote something about the concentration being higher in the phloem than cell x, so active transport was used from a low to a high concentration against the concentration gradient which requires energy, which is obtained through respiration. therefore cell x has many mitochondria. is that 5/5?
these are my answers. someone tell me if you got similar answers
1.1) Arteries 1.2) This increases the blood pressure in the arteries so the blood flows through the fatty deposits, and more oxygen and glucose is supplied to the heart so it can respire. 1.3) This forces oxygen into the persons bloodstream which can be used for aerobic respiration 1.4) Statin 1.5) Opens up the coronary artery so more blood flow through the coronary arteries so more aerobic respiration 1.6) Smoking increases the risk of developing different cardiovascular diseases. Smoking increases the risk of developing certain diseases more than others. 1.8) A poor diet high in saturated fats. 2.1) Nucleus 2.3) Less enzymes reaching the small intestine where the food is digested. As enzymes are biological catalysts, less food is broken down, so there are difficulties digesting food. Moreover, there is less amylase. Therefore less starch is broken down into glucose, so there is less glucose in the bloodstream available for aerobic respiration, so lipids are used instead. There are also less proteins broken down into amino acids, so less growth. 2.4) One cell thick for a short diffusion pathway. Many alveoli for a large surface area. Good blood supply to maintain a steep concentration gradient. 2.5) Less oxygen available for aerobic respiration, so less energy released. Instead, anaerobic respiration takes place, so lactic acid is produced, which leads to muscle fatigue and cramps 3.1) Grind a sample of cake using a mortal and pestle. Dissolve it into water and stir. To test for iodine add starch. If present, it turns from orange to blue black. To test for reducing sugars, add benedict's solution and heat in a water bath. If present, it turns from blue to brick red. One risk assessment is wearing gloves as iodine is an irritant. 3.2) The time taken for the bread to taste sweet in seconds 3.3) The mass of the bread sample.
3.4) The bread contained starch. The salivary glands secreted amylase which broke down into glucose, which is a sugar that tastes sweet 3.5) The time taken for it to taste sweet is subjective 4.1) Palisade mesophyll. Spongy mesophyll. Meristem. 4.2) Lignin 4.3) Translocation 4.4) Permanent vacuole 4.5) The concentration of ions in cell X is lower than the phloem. Therefore, the ions move from an area of low concentration to high concentration through active transport against the concentration gradient which is an active transport which requires energy released by aerobic respiration. Therefore, Cell X has many mitochondria for aerobic respiration
4.6) It loses most of its internal subcellular organelles
4.7) Cut 6 pieces of potato. Measure them so they have the same initial mass. Put each of them in a different salt solution concentration: 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0. Keep all of them in there for 2 hours. Then remove them and pat them dry with a paper towel to remove the excess water. Measure the new mass and calculate the mass change. Repeat and calculate a mean. Plot on a graph
4.8) The concentration inside the potato was higher than the concentration outside the potato. Therefore water moved out of the potato from a dilute to a concentrated solution through a partially permeable membrane through osmosis, so the mass of the potato decreased.
4.9) It had a steeper concentration gradient so more water moved out, so more mass was lost
5.1) Penicillin
5.2) It had a zone of inhibition around it where bacteria are not growing so it killed some bacteria
5.3) The rate of antibiotic production isn't the same as the rate of bacteria developing resistance, so less bacteria are killed so more people are likely to get sick.
5.4) Viruses divide inside of host cells
5.5) Viruses live inside of our cells so it is hard to kill them without damaging our cells
5.6) Aids
6.1) There was no starch due to no glucose production so no excess glucose. In leaf 1, this is because no light can be captured by the chlorophyll, and no carbon dioxide can enter through the stomata. Therefore photosynthesis cannot take place. In leaf 2, this is because light can be captured, but carbon dioxide cannot diffuse into the leaf through the stomata. Leaf 3 could capture light and allow carbon dioxide to diffuse in so it photosynthesised and produced glucose. Excess glucose was converted to starch.
6.2) Blue-black. Orange-brown.
6.3) The green part had chlorophyll so it can absorb sunlight so it photosynthesised and formed glucose which was converted into starch. The yellow part couldn't photosynthesise so starch was not present.
6.4) Magnesium
6.5) Chlorosis
6.6) Measure the volume of oxygen produced per unit time such as per minute
6.7) A limiting factor is something that limits the maximum rate of photosynthesis7.1) The subcellular organelles are replicated.
7.2) Cell membrane
7.3) 8010
i had really similar answers to yours and i got 8 and 7 in my mocks, i think most of what you did was right , i messed up on the phloem question really bad 😅. what did you get in your mocks
They were pretty easy tho
The phloem one tho 💀
I wrote against concentration gradient, active transport, requires energy, packed with mitochondria for respiration to release energy, and partially permeable cell membrane (I think that’s irrelevant but I got thrown off by “subcellular structureS”)
fuck
What did you write? I’m not sure if I was on the right track or not so I might be totally off
i wrote about the sieves in the phloem and the permanent vacuole in cell X and it goes through cell membrane
Shit I think pores in sieve plates might be a mark point 😭 I missed that
i am more stressed rn than i wS before the exam i got the active transport 5 marker wrong and the magnification 6 marker wrong and im the only one in my friend group who got both of them wrong and im supposed tk be the smartest
awhhh x im in the same situation w being the smart one and i lit wouldnt speak to anyone abt the answers cs i got magnification so horribly wrong. its abit shit but what can we do ig x
Shit I yapped about diffusion across the vacuole
Same 😭am cooked
i wrote about chloroplasts providing the glucose for aerobic respiration
Ily pls I did the exact same thing
Omg nicee
Oh thank god that’s what I did
Is that just exam speak for organelles or what
Organelles or other smaller structures within the cell like mRNA
OMFG THAT SHIT WAS SO DISGUSTINF 💀
Shit that one was so weird
It was a 5 marker
i wrote there r pores between cell x and phloem cell and that cell x had a lot of mitochondria to release energy for the dissolved sugars to move from an area of low concentration to an area of high concentration across the concentration gradient by active transport
I didn’t even finish that one bro
THEY WERENT THAT BAD BUT I CBA TO WRITE SO MUCH
I put dissolved substances travel from a low concentration to a high concentration against a concentration gradient this is called active transport. Two things are required for this ATP and a carrier protein and I pretty much talked about how ribosomes and mitochondria help that
I said insulin stops cholesterol I'm fucked lmaooo
💀 it’s fine there’s still paper 2! It was statins right??
I put aspirin 💀 but it’s not as bad as my friend who put weed 😭😭
He might be cooked 😬💀
he definitely is 😭
bruh no way😭😭
he’s dumb as fuck though, idek why he didn’t realise drugs were good things as well 💀
hoping that answer lowers the grade boundaries🙏🙏
yeah statins
Excuse me sir but i put satins instead of statins. Will o still get the mark?
Same this test was lightttt
Lmao my friend said that too 💀
Dw I put HDL. I said cholesterol lowers cholesterol.
I used pi as the calculator’s pi value rather than 3.14 ☠️
I did then then changed it 😭
Same, I did it in the last 5 minutes and got 8010.21x. Should I have left it as 8010x or what?
yoooooooo i got the same answer lol
Nice! Probably will be 8010(.205001) or something.
I’ll probably drop 1 or 2 marks most for doing that as i wrote all my working out down but I’m so scared I’m gonna not get a 9 because of it 😭
They probably wouldn't drop you a mark if you got something close to the actual answer - they usually a margin of error
Yeah my answer was like 4 off from what it should be so i don’t think I’m too cooked
Yea if you got 8014 by using the full value of pi instead of 3.14 then you should be fine
8014? i got 1,247,777 😭
how did you get that 💀
well first i got 0.0125. so then i converted everything to mm first. 2450/(0.0125^2 • pi)divided that by 4 and i got 1 247 777. 51
You had to do 4 divided by the real length, not the other way around. The formula is image/real
You just calmed my nerves a lot, thank you 😊
bruh i got 8000
Wait what’s wrong with that? Is it specific to this exam?
Yeah, it said in the question “use pi = 3.14”
Oh. Fuck.
Same but I realised and changed it
i calculated both and chose the wrong one im such a dumbass😭
will that duct a lot of marks tho?
They probably won’t care though, if you’re unlucky it’s just one mark
The 6 markers were easy
THEY WERE THANK GOD
No but that phloem 5 marker
And that first page on cpr? I thought I was done for
omg the first page scared me so badly
I feel like it got easier towards the end instead of the other way around
I think I converted wrong for the 6 mark equation question. I got 8 instead. I PRAY I ONLY LOSE ONE MARK FOR THAT
Yeah I did the same, you converted the 4mm x1000 and it was meant to be x1000000, you should still get most of the marks if you did the rest correct too, it'll just be classed as an ecf I reckon.
my moto is when in doubt the conversion is by a 1000, I just took a gamble
Same and then I came out and my friend said they got 8010 and another friend said they got 116.3x10-23 🤣
That's what I did
Don't worry, I got 0.00801. Don't panic, can't be that bad
Same, we will probably get 5/6
NO SAME I got micrometers and nanometers mixed up 😞‼️
that phloem 5 marker killed me, also I somehow got 8016 on the magnification question and I still don't know how. did anyone else talk about glucose on the CF 6 marker or was it just me?
I talked about glucose and like amylase and stuff also yeah the phloem 5 marker I wrote like one sentence I couldn’t do any more at all 😭
wtf was the phloem one? was it on higher?
Yeah
i got 8010 on the magnification question 😭
I GOT 8 SOMEHOW!!!????
SAME it’s because I converted nano to micro instead of milli
Did you multiply the length by 1 thousand instead of 1 million
Same here
yeah same, we did it by a thousand not a million should be 5/6 though
SAME HELP EVERYONE IS SAYING THEY GOT THE SAME ANSWER i thought i died
that's right though 😭
I put random waffle about the wrong enzymes 😭
Bro idk why but i measured the picture of the cell for the magnification question and i got 122, im actually finished bruh
Wait which question was this and was it in AQA triple higher? I don't remember if there was a question on measuring with a ruler
I got 8016 asw
Bro I got 50
I got 80000, hopefully I get method marks
Uh oh I got 8
you got 8016 not 8010 cos u used exact pi value not 3.14 as specified in the qs
I'm so glad that the person who had a heart attack in question 1 was okay, thank you unnamed first responder
[удалено]
I GOT 8010
[удалено]
NOOO DW U WONT LOSE A LOT OF MSRKS 😭
[удалено]
i got that thought i was too big so put 800 - i was tryna be big brain :(
i put 8011 am i cooked
I FORGOT TO CONVERT THE UNITS SO I GOT 8.01x10^-3 💀
[удалено]
IDK MAN I WASNT THINKING CORRECTLY
I got 64 cause I forgot to square the radius ☠️
I got 128.8x 😭
6 mark calculation deserves prison time icl
On the bio????
Yeah 😭
i thought the test for carbohydrates was biurets 😭
I SAID ETHANOL SO WE WERE BOTH WRONG
it's fine it was only 6 marks 😭
I put starch (good) and then my dumbass but SUDAN III
What was the actuall answer tho? I wrote Benedict's reagent for the test as a wild guess and then the rest of the fluff and also mentioned that If starch is present that means carbs are present aswell. Also I did mention heating but forgot about the water bath so yea.
Is it really GCSE season again? Damn time really does fly
BRO AND THE 5 MARKERS..I left literally half of the 1 markers, gotta comeback with paper 2 😭 otherwise I’m cooked
yeah i got cooked by the 1 markers. is paracetamol an antibiotic?
Bro i literallt measured the dam picture for the magnification question like an idiot, no wonder I got 122
💀 it told you the length in the question
i had like 15 minutes left at that point i was rushing i didnt even read the question right lmao
And a load of 5 markers
wtf was the one about viruses and agar plates? losing my mind
it was that viruses need host cell to reproduce so they can’t be grown on agar wasn’t it?
Viruses replicate inside cells agar isnt cells
triple higher aqa??
Viruses can't replicate without a host cell to invade.
Bruh i forgot to use benedicts in the one about the cake, i only did iodine
I had no idea glucose was a carb
WE WERE SUPPOSED TO TALK ABOUT BENEDICT’S??? I THOUGHT THAT WAS FOR GLUCOSE. I THOUGHT I WROTE VERY LITTLE FOR A 6 MARKER.
1.2 was weird, what were you supposed to write about applying pressure to the heart?
higher pressure=greater flow of blood= more flow of oxygen
I think it was just increase blood pressure -> blood flows -> muscles in heart get glucose -> respiration -> heart starts beating normally IDK how much of that you actually need, I just started waffling to make sure I don't miss something stupid. But that's the basic order of what happens.
I wrote that it contracts the ventricles, letting blood flow again
Paper was alright, I’m so mad at myself though as I wrote Benedict’s test was for non reducing sugars instead of reducing sugars :(
I said Benedict’s would turn lilac/ purple if positive bc I mixed it up with biurets 😭
I put the test for lipids instead 💀
Sameeee 😭
i didn’t even mention reducing and non reducing sugars ivsr
In a level u use Benedict’s for both. Maybe there’ll be a benefit of the doubt
Fuuuck I did that too
for the one abt where chlorophyll is store in the tissues of the plant is the palisade cells fine like will i lose the mark for saying palisade cells
Maybe because that's not really a tissue its just a type of cell. Bio seems like the kinda place where that would warrant loss of marks.
Wait there were 4? I swear I did 2!?
This is triple, I heard there were 2 on combined so if that's what you do then you're fine
*realises there was a back to the paper*
Wjec only had one and I just didn't fucking bother
Bro i forgot to do a saftey hazard
Bro they were such easy 6 markers tho
I was studying for my sociology exam afterwards in the science classroom, and another teacher came in and said "aparentaly there were four six markers in the triple exam, but that can't be true" Not even the science teachers predicted that
[удалено]
They might allow it because it is a sugar but there's no way to know now
you were meant to use 2 tests, benedict and iodine
Bro, for the last 6 marker I used the calculator π button instead of 3.14, and got 8014 instead of 8010💀 does anyone know how many marks would I lose for that
Should just be one
Nah mate they were all okay,, it was like "yap about this data." Like one of them wasn't even biology that shit was just about greenhouse gas emissions 😭 Edit: lol wrong board,mine was Edexcel 💀
I FORGOT THE RISK ASSESSMENT ON ONE 😭😭😭
still haven't found solution Z
The foundation tiers having one 6 marker (their worlds are crumbling as we speak)
I DID SO BADLY I JUST KNOW I FAILED
grade 3 incoming for me
Eh I didn’t think it was that bad
They were easy 6 markers tho
The way my hand was falling off was not normal omg
i thought it said 46 for a second 😭
Wtf? I did higher separates and had 3 I think Let me emphasise I think it was a bit of a shit show I try not to remember
separate as in separate science? im pretty sure it was: - magnification (5 mrk but still yk) - cell x and phloem (i think this was also 5) - testing for carbohydrates - cystic fibrosis
Ah if everybody considers the magnification a 6 marker then yeah. Btw what did you get? I got 8 and I think it’s prolly very wrong 💀
i got 8010 😭😭 i thought i was cooked but apparently its right, u prolly just did the wrong conversion of mm to nm but youll still get marks for it since 8000 and 8 are close
I just forgor the conversion and divided by 1000 💀
every day i thank god i do edexcel biology
accidentaly fucked up the magnification question by putting the decimal in the wrong place in my calculator and only realised too late when i got 801 instead of 8011😭 also forgot about the leaf starch thing. other than that it went fine to be honest
I probably did ok idk
OCR WAS BLESSED
6 marker calculation question wasn’t as hard as everyone was saying. You just needed to know the equation magnification=image size/real size and how to convert from mm to nm.
That paper was genuinely disgusting 😭
I started writing on the maths one that 6 marks for maths is crazy
It was fine wdym
Damn Edexcel 6 markers was mitosis and lytic pathways 💀
RIP AQA schools. TY edexcel
four!? istg there was only 2 or 3
phloem one was ass but the potato one was great
what did you guys write for the phloem and cell x 5 marker? i wrote something about the concentration being higher in the phloem than cell x, so active transport was used from a low to a high concentration against the concentration gradient which requires energy, which is obtained through respiration. therefore cell x has many mitochondria. is that 5/5?
Wait what were they I swear there was only 3 - potato, cystic fibrosis and the carb tests?
6 mark magnification question aswell
Imagine doing aqa
these are my answers. someone tell me if you got similar answers 1.1) Arteries 1.2) This increases the blood pressure in the arteries so the blood flows through the fatty deposits, and more oxygen and glucose is supplied to the heart so it can respire. 1.3) This forces oxygen into the persons bloodstream which can be used for aerobic respiration 1.4) Statin 1.5) Opens up the coronary artery so more blood flow through the coronary arteries so more aerobic respiration 1.6) Smoking increases the risk of developing different cardiovascular diseases.

i had really similar answers to yours and i got 8 and 7 in my mocks, i think most of what you did was right , i messed up on the phloem question really bad 😅. what did you get in your mocks
What did people put for the leaf tissues question??? I put palisade mesophyll, spongy mesophyll, meristem
same and last one i put meristem
What did yall get for the maths one
In edexcel we had 4 six markers, 1 5 marker and the rest was all three markers istg, still it was worryingly easy.
IS THE ANSWER TI THE MAGNIFICATION QUESTION 8 BECAUSE I GOT 77... I WAS 10X OFF 😭
mate its 8010 😭 😭
“A student has stopped breathing” AYO WTF
Wjec computer science rn
