salamz! wat did u write 4 da pH question?

wsalam
I wrote that the optimum PH of different enzymes vary and I proved this with the graph
wbu?

 

[svenas]

okay yeah I get ur question now
1)I wrote that toxic poison (pesticide) build up in minimized <---Don't worry if u didnt write it they could be alot of answers to it
2)Energy intake and nutient intake is more as primary consumers.

i knw i'm wrng, but i wrote, in one solution, da activity peaks @ one day b'coz 2 enzymes produce more amino acids. in da other, da activity peaks @ a later day, which means one enzyme has been denatured, n so activity peaks later. it's wrng!

oestrogen would thicken the endometrium and will stimulate growth of blood vessels

 

[IGCSE O/L student]

oestrogen would thicken the endometrium and will stimulate growth of blood vessels

i wrote oestrogen also prevents da release of FSH, n so prevents da release of another egg.

 

[Chucky]

it was abt ecology, digestion, seed labeling, blood clotting everyone came outta the hall smiling

sounds easy too!

so i guess variant 3 was toughest? or was variant 2 the toughest?

OMG I wrote that for progesterone :O

Progesterone thickens the endometrium

waaaaiiittt!!! i'm not sure of my ans! i think i'm wrng n u r ryt?

 

[wooowooowoo]

sounds easy too!

so i guess variant 3 was toughest? or was variant 2 the toughest?

Variant 3 gave their exams already? V2 was more complexed compared to V1

 

[IGCSE O/L student]

reaaallllyyy? oestrogen stimulates da ggrowth of blood vessels.

 

[IGCSE O/L student]

Variant 3 gave their exams already? V2 was more complexed compared to V1

we predicted sum of da questions myt cum, n all of dem appeared in V2, we did V1

 

[Chucky]

Variant 3 gave their exams already? V2 was more complexed compared to V1

Agreed.

Progesterone thickens the endometrium

doesn't progesterone maintain the endometrium ie.maintain its thickness caused by oestrogen?
