A-level biology paper 42

[ABC12348]

about that isolating mechanism question. doesn't reproductive isolation take place in both mechanisms? because in allopatric species can not interbreed which eventually leads to reproductive isolation. the reason i wrote alloptaric and sympatric.

 

[ABC12348]

Anyways, what do you think the gt will be?

and what do you think will be the gt?

 

[moh321]

A B C.
was A= RuBP B=fatty acids C=Glucose ?

I think c was nitrogen because protein is made

 

[ABC12348]

all i know is that TP is converted first into glucose. from there it is converted into other substances so i wrote glucose.

I wrote Allopatric and Sympatric speciation
