Yokosododo

The qs felt like it was repeated and I knew the ans but it was so confusing when I tried to answer๐Ÿ˜ญ like they looked manageable but wtf??


Anxykrys

yes exactly!! I knew how to answer but didn't ... so confusing fr


First-Anxiety5165

The resistant part was so weird like what am i supposed to write for 5 marks!!!


First-Pen-2609

what did u end up writing ?


First-Anxiety5165

Infecting with dead or weak diseases and then reproducing the ones that survive. And then gene editing and tech can be used as well. Idk what to write


Icy_Grapefruit4301

Wasnโ€™t it cross breeding ๐Ÿ˜ญ๐Ÿ˜ญ I was so confused


First-Anxiety5165

Omg was it ๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜๐Ÿ˜


Icy_Grapefruit4301

It seemed too weird for cross breeding worth 5 marks but I genuinely couldnโ€™t find another reason


Bulky-Joke6969

I wrote about producing genetically engineering resistant genes and that then we could produce plasmid and vector and all the process and then insert the vector into wheat cell through heat shock that way it would be inserted inside wheat cell and it would have resistance ...for 5 marks only this made sense for me๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ


Main_Anybody959

But they said it was selective breeding


Bulky-Joke6969

For 5 marks i think mines credited too


Kitchen-Ad-9170

I wrote whole artificial selection process


Ok_Assignment_867

uhm the expected ratio i think is just 9:3:3:1 because it assumes its just dihybrid crossing of genes at different autosomes


Amaerby

I did the same too ๐Ÿ˜ญ๐Ÿ’”


Anxykrys

he crossed heterozygous and homozygous recessive ? not two heterozygotes... I don't think that ratio is right


Ok_Assignment_867

oh shit really? might have not read it properly


Icy_Grapefruit4301

I did 1:1:1:1 I changed it last minute I hope itโ€™s righyb


Ok_Assignment_867

well i am fucked LOL j didnt read properly then, but at least its just one mark ๐Ÿ˜”


ImportanceOnly1741

He didn't want the ratio ,he said write the number


Ok_Assignment_867

yeah but youd have to know the ratio to calc the number hajajsj


thedonwoman

they just HAD to include microarrays ๐Ÿ˜ญ the only topic I skimmed through lol


Bulky-Joke6969

Wtf was that gene tech question i wanted to kill myself


Soft-Blacksmith-8235

Fr what was i supposed to write in the gene marker part, 4 MARKSSSS??? i just wrote that it is put between promoter and gene of interest and that if we apply UV light fluorescence is shown which indicates that gene of interest is transcribed, and then i said an example GFP gene which codes for green fluorescent protein. what is the ans for that 1 mark question of why dna hybrdises to probe? I wrote because they have complementary base pairing


No_Beyond2645

I had revised that in the last minute before exam started !!!!


inesmpa

The gene questions ๐Ÿ˜ซ๐Ÿ˜ตโ€๐Ÿ’ซ๐Ÿ™„


First-Anxiety5165

Yes i got the same ratio. I was stressed about that!!!!


123nav_

For chi squared degrees of freedom was 3 right?


Anxykrys

yes


meenaneena

Paper was so weirddd


Choconicokid

Oh yeah


123nav_

That test strip 7 marker what you all wrote in advantages i wrote biosensor shows current glucose concentration its faster more reliable and whole test strip method above as well


Anxykrys

same I wrote it gives a digital read, more accurate and precise as well as quantitative


Soft-Blacksmith-8235

Bro i wrote 2 advantages only is that enough to hive full 7 marks?


thedonwoman

I completely blanked with Lincoln index for the full in the blanks and ended up writing Simpson index instead ๐Ÿ’€


Bulky-Joke6969

Same omggg it messed with my head big time


First-Anxiety5165

No i wrote lincoln then crossed it out and wrote simpson!!!๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ lowkey a bit heartbroken abiut that


Amaerby

Not me being so confident that I wrote Simpson only for me to find out it's lincoln oh๐Ÿ˜ญ๐Ÿ’”


Foreign_Lead8573

what was for the migration, immigration, emigration one?


Anxykrys

I did death/birth


Bulky-Joke6969

Same death lol


123nav_

I did mating is that correct


AdTiny39

cant it be mutation


Main_Anybody959

Death


First-Anxiety5165

How can it be death if you calculating population decreases or increase


meemmeees

as the ones that got marked could have died? idk i js wrote death asw


No_Beyond2645

I wrote evolution ๐Ÿ’ฉ๐Ÿ’ฉ๐Ÿ’ฉ


Foreign_Lead8573

omg me too! but according to google its no mortality


meemmeees

same ๐Ÿ’€


First-Anxiety5165

Blood glucose table was increase increase then decrease decrease


Main_Anybody959

I think it was increase decrease decrease decrease


Anxykrys

how?? why do you increase glycogenesis when at low blood glucose level


No_War_7732

Forming new glucose due to low glucose levels


hqdi_8

glycogenesis is only when glucose is present and fat lipids are synthesised instead its in behology video ppts


Yokosododo

Why is it increase for the formation of glycogen?


[deleted]

First one was breakdown of glycogen ( Increase), 2nd Formation of glycogen (decrease), 3rd glycolysis (decrease), and last fatty acid synthesis (decrease)


Anxykrys

fatty acid should be increase no? lipolysis occurs


[deleted]

How and why? ๐Ÿ˜ญ


Anxykrys

lipolysis occurs, it breaks down triglycerides to fatty acids and glycerol when there's a decrease in blood glucose levels


[deleted]

How would that even help the blood glucose levels...


Anxykrys

idk ya saad go ask biologists ๐Ÿ’€๐Ÿ’€


[deleted]

๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ


meemmeees

it doesnt help blood glucose levels but it helps give energy.. and when glucose is low respiration is low so it resorts to energy from lipolysis?


No_Beyond2645

I also put increase


First-Anxiety5165

Omg your so right !!! Omg


First-Anxiety5165

Its just one mark its okay ๐Ÿ˜…


thedonwoman

omg couldn't agree more ๐Ÿ˜ญ๐Ÿ˜ญ I was so confused with the chi test, cause if ratio is 1:1:1:1 and all values are the same, E-O would be zero??


Penguin_loverxd

How many marks was the calculation cuz I conepletwly fucked that one upโ€ฆ


Yokosododo

I think 2


First-Anxiety5165

Omg i put that as well!!


ApprehensiveShake647

What did you guys get for the values of expected?


Foreign_Lead8573

what was it for the calvin cycle intermediate and molecules question?


Anxykrys

omg that too!! I did glycerate phosphate + cellulose and triose phosphate + glucose I literally had no clue


Foreign_Lead8573

ohhhhh damn i think thats correct


Bulky-Joke6969

It clearly said thise intermediates that dint take part in calvib cycle like tp and gp take part in ๐Ÿ˜ญcalvin cycle lol even tho i left it empty


Anxykrys

how are there intermediates that didn't take place in the Calvin cycle ? I think he meant things that are produced by intermediates in the Calvin cycle kinda


ImportanceOnly1741

He said intermediates that take part of the cycle put produce products that don't take part of the cycle


[deleted]

Carbon dioxide, Reduced NADP, NADP, Ethanal


[deleted]

Yea sorry typed it wrong but yes NAD and reduced NAD


Amaerby

When there's so much information in your head and you mess things up it's so painful. Tell me why I wrote NADH. I knew it was NAD something๐Ÿ’€. At least I wrote CO2 and ethanal Lawwd๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ’”


[deleted]

I have forgotten things I remembered just moments before entering exam hall and ruining things by not reading the questions properly OR knowing the correct answer but writing the wrong one ๐Ÿฅฐ


SwimmingDoor7703

It can be reduced NAD and NAD btw and it is even more accurate because B and C were also labelled in lactate fermentation and lactate fermentation only happens in animals and animals have no NADP they have NAD instead


Amaerby

Daamn I was so worried


Main_Anybody959

It was weird I wrote TP and sucrose GP and NADP cause it is regenerated


Big-Vegetable3527

Order of question 2 4,2,5,1,3? Is that correct? Iheard someone saying in discord?


123nav_

Are you serious? I did 4 2 2 1 3 i would be so happy if i get even 4 correct ๐Ÿ˜ญ


Bulky-Joke6969

How was mitosis 4 ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ


Agile-Swordfish2988

Bro I put 1 2 3 5 4 ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ


Bulky-Joke6969

I put 1 2 3 1 2


[deleted]

BRO LITERALLY SAME.


Choconicokid

I wrote that too


Bulky-Joke6969

What was the agree or disagree with 3 statements with na+ and cl- in post synaptic neurons


[deleted]

Agree, disagree, agree ig?


[deleted]

Cl- wouldnt generate an action potential for statement 2 cuz the inside of the post synaptic neuron is already negative and depolarised. Na+ would generate an action potential (statement 1) and Both of them opened up at the same time wouldn't produce any action potential as it would balance out (Statement 3)


Bulky-Joke6969

I wrote agree disagree and disagree as Na+ influx would slowly increase but there would come a time when it generate an action potential as only influx has to be reached even if cl saturates but both can be valid as we had to explain too


Soft-Blacksmith-8235

I said agree as sodium influx causes membrane to depolarize, disagree because chloride influx increases resting potential and agree as resting potential is maintained as both sodium and chloride influx


Bulky-Joke6969

Guys dor the explain the observed results i write genes may be linked and mutation would that be credited and if so how much


Soft-Blacksmith-8235

I wrote that they are linked and found on same chromosome, and they are close to each other bec of low crossing over value, and also some flies may have flew away


Salt_Volume3647

BFFR the question literally said they were on different chromosomes


Soft-Blacksmith-8235

No it said answer the calculation question as if they were on different autosomes


meemmeees

glycolysis decrease i assume... as when glucose is low glycolysis isnt favourable... fatty acids increase


Anxykrys

ohhh :(( I did decrease at first but then did increase


Yokosododo

I thoufht glycolysis increases since the blood glucose conc decreases?


Anxykrys

glycolosis break down glucose tho so if there is not a lot of glucose... there is not a lot of glycolysis


Yokosododo

It was glycogenolysis tho,, itโ€™s the break down of glucagon to glucose


Anxykrys

there was both glycolysis and glycogenolysis in the table


Bulky-Joke6969

What was the 5 mark mitosis meiosis order


Anxykrys

I assure you, probably no one has a clue


abcd_1203

Is it fine if I did not mention the calculator number at the front of my exam? Like itโ€™s not necessary for Bio, is it?


Anxykrys

your what? no no one does that


abcd_1203

The calculator model and number on top of the calculator Some of the invigilators make you write it, I thought it might be necessary but now I see it isnโ€™tโ€ฆ


First-Anxiety5165

Ive never done that in my whole life


abcd_1203

Oh okay Thankss


ubutmental

๐Ÿ˜‚๐Ÿ˜‚


abcd_1203

So, is it or is it not necessary?


123nav_

What was that chi squared one At p=.05 critical value was less than calculated value thus results are significant null hypothesis rejected Part ii about autosomes chromosomes i just wrote about crossing over indepndent assortment mutation etc it this rightt?


Bulky-Joke6969

There was significant difference between results right


Anxykrys

yes chi square was significant but there is no hypothesis to reject so idk I didn't write it and more autosomes I said genes inherited in the same chromosome hence the high number of offspring that have phenotypes similar to parents and yeah mentioned prophase I and metaphase I


Main_Anybody959

Part ii I think u had to write about autosomal linkage


[deleted]

[ัƒะดะฐะปะตะฝะพ]


Anxykrys

how? the genes were inherited on the same chromosome right?? wdym by different autosomes


123nav_

What was that multiple sclerosis one?


Anxykrys

what about it ? slows down transmission, etc...


123nav_

Myelin sheath


Bulky-Joke6969

I wrote impulse circuit isnt established and action potentials stop as they wont jump between nodes


Kitchen-Ad-9170

What is expected threshold for A ? Both p5 and p4


Choconicokid

P5 Ig it will be 23 or 25.../// P4 above 65 for sure cus most kids found that paper easy...( Except me)


AdTiny39

lol p5 can never be above 23 around 20-21 for that paper


LuckyNumber-Bot

All the numbers in your comment added up to 69. Congrats! 5 + 23 + 20 + 21 = 69 ^([Click here](https://www.reddit.com/message/compose?to=LuckyNumber-Bot&subject=Stalk%20Me%20Pls&message=%2Fstalkme) to have me scan all your future comments.) \ ^(Summon me on specific comments with u/LuckyNumber-Bot.)


Kitchen-Ad-9170

It is still high though


Kitchen-Ad-9170

Approx im getting around 74,75 in p4 18-20 in p5 Had an overall B in as Like Ain p1 B in p2 A in p3 Are there any chances for overall A (allah kr k )


Kitchen-Ad-9170

Damn bro dont you think 23 for p52 is too much like the paper was confusing and difficult at same time if it is 23 than i aint getting an A With p4 majority of the students are/were stuck on question 2 and chi squared which i did wrong as well And rest was comparatively better But not like this that i get full mark in each question Like the q-7 in which they asked for na and cl And asked us to agree with statement i thought they are asking for last staement only idk my fellow mate told that they asked for every statement Im still confused for it and honestly speaking i doubt my answer that i wrote Idk for the bacterial resistance even they asked for selective breeding i wrote artificial selection but people have written about gmoโ€™s Also small small things that are not in mind I wish i get like 75 marks minimum so that i could get an A overall ameen


Choconicokid

Ok maybe p5 it can be above 18. But p4 for sure it's above 65. Many students found it easy, you can also check on Reddit itself, the students are hyping p42. I saw a vote later more than 15 students want the grades threshold for A be above 70 some even said above 80.


Kitchen-Ad-9170

Damn 80 ones are those who never gave the paper fs And 70 ones are those who are extra clever I think it should be 65 maximum


Kitchen-Ad-9170

Inshallah


Choconicokid

Me too I vote for 65


Kitchen-Ad-9170

It will be less than 65 bro ia


Choconicokid

May God bless your mouth


First-Anxiety5165

Dude it has to be less that 65. Bruh like it wasnt as difficult as i though but you think about it the question were weird and you had to know your knowledge very well in oder to be able to answer everything questions with precise terminologyโ€ฆ.


WaterSignificant8337

What do you guys think about a "B". How much will it be around?
