Because that much detail is not expected at this level.oestrogen inhibits gnrh release from hypothalamus so this have negative feedback ob both FSH/LH release from anterior pituitary gland
why in MS they only write that oestrogen has negative feedback on FSH alone
human gas exchange surface I THINK IN such qs u dont need to mention anything about ratioHi guys, can someone clear my doubt regarding this examiner report comment
'Candidates lost credit by stating that the alveoli have a large surface area to volume ratio'
This relates to the question:
'Describe and explain how the structure of the human gas exchange surface is adapted for maximum efficiency'
Are you giving AS only?Hello
I wanted to ask as only a month left how should I be revising biology?
YesAre you giving AS only?
The significance of Vmax and Km values:Significance of Michaelis Menten constant. Plz anyone explain ?
ER:How comes photosynthetic prokaryotes do not need chloroplasts to photosynthesize? It's CView attachment 60065
Hey sorry I don't think I'll be much help on this.Help (
yep, as per your instructions I do read ERs now, but this one, I was just solving yet and this question was buggin me a lot. But the thing is we didn't learn this in the syllabus! did we? I read both books more than once and not a single word about photosynthesizing prokaryotes was mentioned! This is just not fair! And to think about it, aren't 80% more population in favor of the chloroplasts to be in prokaryotes!, but the 80% 'less able candidates' I come in the category of! Ahh! :/ER:
Whilst nearly 60% of the more able candidates answered this correctly, over 80% of less able candidates did not realise that prokaryotes do not have a cellulose cell wall or any organelles such as chloroplasts.
Even I got this question wrong.Because by seeing that the last one is chloroplast and question said photosynthetic I did choose the option that had 5.yep, as per your instructions I do read ERs now, but this one, I was just solving yet and this question was buggin me a lot.

It's written in the book. Prokaryotes, no matter they are photosynthesising or not, they don't contain organelles. Cell-wall in prokaryots is made up of peptidogylcan (murein) .yep, as per your instructions I do read ERs now, but this one, I was just solving yet and this question was buggin me a lot.

Don't be sorryHey sorry I don't think I'll be much help on this.
But I was wondering why have you highlighted 0.5?
Nice timing.It's written in the book. Prokaryotes, no matter they are photosynthesising or not, they don't contain organelles. Cell-wall in prokaryots is made up of peptidogylcan (murein) .
