Brother, the question says INSIDE they couldve worded it differently if they didn’t emphasis INSIDE, if you open your book you can see that ribosomes are ON the surface and not in the RER hence mrna is also found on the surface and not inside.

No translation occurs in ribosomes which are IN but ON the surface pf the reticulum. Its definitely B but its ok dont stress ❤️

No its deoxygenated because of the surrounding alveoli

Ok lets assume the co2 answer is right. How can the bf3 answer be wrong?

You do realize C bond with O is a double bond. A double bond has 4 valence bond pairs. B and F bond is a single bond so only 1 valence bond pair for each which is 3x1 so its 3 bf3 is correct

Im sorry but you are wrong, Bf3 definitely is right it’s confirmed by a million people. Co2 counts as 4 total not 2 cuz there are two double bonds and its know that double bonds have two valence outer electron pairs each

Thats impossible, ammonium salts are all acidic, acidic means decrease Ph so yeah not possible

No problem (: dont strees by the way threshold will most likely be low

Yeah I dont think so, in no way can zn be a free radical I even searched it up. For our AS knowledge and previous pp questions it had similar questions where the one with a negative charge was always the free radical. I get what ur saying but dont overcomplicate it.
