OCR A2 Biology F214/F215 Resources Thread

Hey,

I've posted a few resources on the other thread, but, over time, they have become scattered almost everywhere and are becoming difficult for people to find. So, as requested, here's a thread with them attached.

I will continue to update this thread from now with the questions I make for each topic. Some of the files are attached to the thread itself, others are given by links to my site, simply because they are too large to upload otherwise.

Hope you all find them useful!

Note: Figure 2.1 is immensely small because I just didn't have time to play around with photoshop and make it fit, so when answering the question, you may want to look at the insert to see the enlarged, intended version of it. Question 3 is also incorrectly labelled, it should be part (a), then (b), (c) and (d), rather than (f), (g) and (h). Apologies!

I made the questions up for practice. It's not necessarily a prediction, but I think other topics will probably make an appearance, but it's just extra practice.

Your questions are ace!! Super useful, so thanks :biggrin:

. Are you planning on doing a series at all on the Ecosystems and Sustainability topic in the textbook?

Doing photosynthesis right now, I will do that after - I need to go over it myself too! :biggrin:

Just wondering, but will you be doing anymore questions for F214?

Would you also mind explaining the first MS point for 'explain the purpose of the enucleated ovum' ?

Hey @kingaaran I also find your questions really useful! Would you be able to do some questions on peripheral/autonomic nervous system (pg230-1) the various different types of muscle structures (pg234-5), and the interlink between the muscles, nerves and hormones (pg 238-9)?. There was a hard question (q2 of the jan 2011 f215 I think) which merged all of these topics, and since there aren't that many past paper questions on it, I was wondering if you would be able to write any? Not so much on the sliding filament model as I know there are loads of questions available on this online, and the concept is pretty repetitive.

Thank youu :biggrin:

Hey man, brilliant resources!

They're really helping me consolidate my knowledge and practice applying ideas which I need. Any thoughts for some questions on meiosis and genetic problems (epistasis, genetic crosses etc)?

Thanks!

Sure, will add that to the list :smile:

Gametes are produced by meoisis and so they will vary in their genetic makeup to somatic cells because meiosis does not produce genetically identical cells.

If we want to clone an animal, it is best that we do not take an egg cell from that animal because this will not be the same as the animal we want to clone. Instead, we take a somatic cell from them, an egg cell from another variety of the animal, and combine them, so that we have both the DNA we want and the right cellular conditions for growth.

Thank you very much!

Could you please explain whether plant roots undergo negative phototropism, as it makes sense it terms of the direction of their growth, but also is rather contradictory as roots cannot directly respond to light intensity, as they're not exposed to it (underground)?

Likewise, can you say plant shoots exert negative geotropism?

Hey man, any chance you have the genetic profiling answers? If not you haven't finished them yet, no worries. :smile:
