I said yeah coz they share a common ancestor

dammit!!

did you talk about all the glycogenolysis and glycogen to glucose for ATP for the why is glycogen present?

They better be low as hell, I thought the Jan paper was actually alright!! This was like :

I didn't write splitting embryos. I wrote nuclear transfer, then you can split the embryo that has been created by nuclear transfer to insert it into more surrogate goats.

And the question didn't ask for one clone, is said how they would clone to make a population.

i thoguht no cause they are not disticnt as they have sam biochemistry e.t.c?

Was the process shown succession and I didn't write primary would I still get the mark


This was posted from The Student Room's iPhone/iPad App

ikr! And i couldnt help but smile at the cats ...

It was in terms of phylogeny not the biological thingamabob

I Put no - my reason was all muddled up though :/

no i9t was taxomy and that is the study of classification

For the question on how increased H+ ion concentration reduces the force of muscle contraction:

I wrote about how H+ ions would change pH, interfere with bonds between R-groups, disrupt tertiary structure and possibly denature myosin and actin so cross-bridges can no longer be formed.

I also said it H+ ions might disrupt membrane potential and cause the sarcoplasmic reticulum to release less calcium ions.

Would that attract marks?

Oh no, I only wrote succession too primary/secondary didn't even cross my mind D:

No was the cocrrect answer because their most common ancestor was the same common ancestor of ALL the species therefore if you'd have to say all are the same taxonomic group if this was the case which it isn't =)
