What did you write in the artificial selection one?

Naah wont cross 70

Can someone tell me exact question on insulin section b? And its a part too
Having panic attacks that i read it wrong

Benefits of human insulin produced by gene technology

Benefits of human insulin produced by gene technology

That was a section a type question in past papers
Low chances of immune response
Ethically good as people object to insulin produced from animals such as pigs
Good for people who are immune to animal insulin
It is more effective and effect is lasting
It is exact fit of human insulin receptors
its more cheaper to produce in bulk amout

 

[Faiqa Nadeem]

I hope 190/270 makes an A :/

 

[anonymous1122]

It would make an A* at 190
A is always around till 170

I dnt know my brain just stopped working or something cuz i think i lose 2-3 marks in it
And wht about the electropherosis question?

Well i wrote all chemistry electrophoresis points in that

Hopefully
And another question, I took my AS last year but I got a B so I took it again this year
I checked my component marks and I had an A in the practical so one of my teachers told me that since I selected the marks carried forward option too the best component grades from AS and A-level will be counted. will they make an overall grade based on the best component grades or will they consider the entire overall AS grade
Because I want my last years practical grade to counted just in case I don't do well this year

Well i too got a B and am repeating this year along with A2
But our teacher told us the entire AS grade is considered in choosing that option not just component grades.

That sucks

 

[anonymous1122]

That sucks

You have the practical tomorrow?

 

[Faiqa Nadeem]

No

You have the practical tomorrow?

Nope mine is on the 26th it's 34, what about u?

 

[princessnoor]

Well i wrote all chemistry electrophoresis points in that

Hey plz tell me how much marks can i get , i wrote these points
-dna sample extracted
Cut using restriction enzyme
Sample added in agaraso gel in wells
Dc current applied
Electrodes connected
Fragments move toward annode as phosphate in dna has negative charge
Labeled using radioactive probes and X ray film
Electropherosis used in dna analysis eg analysing tissue samples in addults amniocentesis in embryo
Oh and also tht each dna sample hve different VNTR regions so can be identified

 

[anonymous1122]

No

Have it tomorrow ._.

Probably full

Have it tomorrow ._.

Probably full

Good luck

Reallllly????

 

[anonymous1122]

Good luck

Thankyou
And dont worry you'll do even better in this year's practical IA !

What did u guys write for the one about why dendrites have more mitochondria than axons

 

[princessnoor]

What did u guys write for the one about why dendrites have more mitochondria than axons

I wrote that more energy required in dendrite part cyz synapses present and many dendrites comaprrs with single axin so have more pumps

 

[Princess Raven]

I wrote that more energy required in dendrite part cyz synapses present and many dendrites comaprrs with single axin so have more pumps

Pumps? Can u say interms of transmission of nerve impulses occur through dendrites which require 47% percentage energy..
Or is that completely wrong XD
