Not 100%, but I think antibiotic resistance, and ability to take up new substrates. Ie, a different sugar for glycolysis. There are many other answer too
For the apoptosis question, I believe A to B was the formation of eyelids/ eyelids opening/ tissue holding eye lids being destroyed. From B to C, I was definitely the webbing between fingers and toes being destroyed. The cockroach was Negative (Photo)taxis. The question of bacteria taking up plasmids, was something along the lines of possibly antibiotic resistance and or taking up new substrates for respiration Do people agree with this? I found this paper annoying to answer, but quite fair. Grade boundaries will go up, maybe 63 A. Or am i being optimistic aha.
I got everyanswer you just mentioned. Hope it's 63. Lol. But I think it will be here.
Wasn't the question on mice, 'black mice are rare, a person want's to get a population of black mice only but only has two grey mice to start with'. Doesn't even make sense why would anyone want grey mice and plus grey was dominant to black.
These are all i can remember, sorry if some are wrong :
1) Carrying Capacity 2) Biotic factor : food availability ( the prey) Aboitic : water availabilty 2) DNA, polypeptide, tertiary structure 3) Regarding the coppicing question : I wrote for aesthetics : they can be made into furniture (idk) it promotes biodiversity as it produces new habitats (ethical?) 4) Question regarding apoptosis In A you can see the formation of Head and Thorax In A-B you can see the formation of arms and legs In B-C you can see the formation of fingers, toes, and ears.
5) Homeobox genes are found in animals , plants and fungi. 6) The mice question i dont remember much 7) The galapocas island question the probability is 25 % as it asked for recessive sea salt water spray It increases over time due to natural selection , where the plants with those alleles are basiacally more likely to survive than those that abosrb the misty water , therefore they more likely to pass genes to offspring , soon there is will be a genetic drift in where the recessive alleles will be more common in population. Human activity on galapocos : i wrote about pollution ( oil spill ) deforestation (loss of habitat and over fishing and hunting ( endangering the species ) Finding about the abundance of the species: use belt transects and quadrents, count how many and where they are founds for the two zones. Goldern rice question : so weird since the answer was sort of in question itself ? The maize plant probably produced the most b-caraotene since it has a different shaped enzyme which is more complementarty to shape of subtrate, different sequence of amino acids so different protein formed etc.
shows phototropism when shoot grows towards sunlight . Gene sequencing : Step 3 should be between 1 and 2 and Transferase enzyme should be restrictive enzyme ?
Last question was aabout somatic and germ line gene therapy : I said somatic changes cell of individual but germ line changes sex cells so offspring also dont get disease.
The term used to describe what happens on the food chain : feeding ? Hawk , since it was further up food chain and therefore had least energy since most were lost through respiration and waste. Chimpanzee question , i thought it was natural selection since the question stated they were lighter therefore could get to the higher branches ? why they were stronger muscles compared to humans ? becuase they use it more regularly and pretty much hang their weight on it , but humans don't ( i basically said, they exercise, but humans don't lol )
CNS vs Peripheral Cns consists of brain and spinal cord - coordinates message Peripheral involves all the neurones connecting brain and spinal cord to all parts of body.- transport message to all parts of body.
I put taxis down for the debetable question, but since we have a issue over the answer ignore it.
these all i can remeber please tell what you agree with and what are wrong .
Much appreciated
you know for the cns vs pns one; I thought the question asked to tell about effects on external environment. So I wrote things like PNS detects change in temp and hypothalamus in brain causes shivering/sweating, and how cns causes contraction of voluntary muscles in response to danger etc. I didn't think it was to compare them?
Most of Jan 13 was filling in spaces and ticking boxes!!
No it will be lower because there were a lot of questions regarding application whereas Jan 13 was knowledge based so if you knew your content you were good

Yeah that's what I'm saying, it can't possibly be the same as Jan 13!

that question was a pretty vague one... though it did say "you don't need to quote specific regions (+maybe their functions) in the brain, just the roles of PNS/CNS in responding to the environment

I don't think you'd get any marks - it's not really answering the question.
The marking points will probably be:
PNS involves all the neurones going into and coming out of the spinal cord and the brain ;
it carries impulses to the CNS via sensory neurones / detects stimuli ;
