Congrats to you too! Omg, don't worry same! I don't understand it either tbh ahaha, I worked it out via process of elimination and many MANY diagrams :')

Why would the fatty acid produce more energy per mole than per mol of glucose??? "Number of molecules are NOT shown", doesn't that mean you can't know? In the diagram there is no input of oxygen before the conversion to acetylcoA - anaerobic?

I thought 12 short answer would have been b when pyruvic acid is meshed with fatty acid to make acetylcoA??? anyone else?

Can someone explain to me how it was a substation mutation in a gamete and not a somatic cell? question 23 if i recall correctly.

[zxcvbnm,]

In the original post, there's a hyperlink

(Also - does everyone still agree with the original answers in the OP? - has there been any changes?)

[bonkbadonk]

Yeah I think they're correct (in my esteemed opinion)

[rendeme]

Could someone explain how question 19 is cytotoxic t cells, because I thought cytotoxic T cells only killed virus infected cells?

I though since the question said there are individuals (emphasising the plural) with this mutation, this indicates that the mutation does not apply to only one individual, hence for it to be passed on to other individuals (offsprings) it has to be a mutation in the gamete.

Ah I see... didn't pick up on that!
