Higher Biology Exam 27th of May

can anyone remember any answers please i need at least 55 marks in paper 2 to be able to go to uni

0.8 BPM for that heart rate question calculation, the second to last question was co - operative hunting and less energy is used per individual (any advantage of co - operative hunting).
The first question was: state what is found at the 3 prime end of a DNA strand
Answer: deoxyribose sugar
Another question was: state why ligase isn't needed in PCR:
Answer: both strands are replicated continuously
Another question was: suggest why human DNA polymerase isn't suitable for PCR.
Answer: it isn't heat tolerant and so would denature
Another question was: calculate the percentage content of primers in the tube.
Answer: 1.6 percent.
The last question just before the extended response was asking you to state how wild dog number found be increased due to habitat fragmentation causing a decrease in number.
Answer: habitat corridors, allows them to recolonise fragments, gain access to more food and mates so they can survive and reproduce.
For the final extended response, I chose to do how the animals survive adverse conditions. This will take ages to write but I'll summarise what I talked about:
Aestivation - dormancy to survive excessive heat/drought.
Daily torpor - period of dormancy done as a 24 hour cycle for a certain period of time. Done in animals with very high metabolic rates.
Hibernation: to survive freeIng, winter conditions.
Definitions of: Dormancy, predictive dormancy and consequential dormancy.
I do remember some other things but it will take ages. I hope what I have said has been of help to you and can help you be a little more confident. Remember, exams are done so enjoy the summer and relax.
Other stuff I remember:
Q: state the function of DNA polymerase (I think it was something along these lines)
A: to add nucleotides to 3' end of primer.
I also remember a Q where you had to describe alternative RNA splicing but I don't remember the wording. It didn't tell you to do this the Q was like:
suggest how different enzymes can be produced
from this gene.
A: alternative RNA splicing, this is when different combinations of exams are spliced together.
Q: suggest why selective herbicides are more effective when used against other crops than wheat.
Answer: selective herbicides are more effective against broad leaves plants, they're not very effective against narrow leaves plants.
Q: state another problem, besides toxicity to non target species that can arise from use of pesticides.
Answer: bioaccumulation (or others)

What did you get for 7 on multiple choice about cell membranes and ATP synthase, pores, histone etc

i just wanted to ask for the adverse condition question did i have to talk about migration too because i swear it asked how animals survive adverse conditions so i only mentioned dormancy and didn’t say anything about migration as i thought that was more of avoiding adverse conditions rather than surviving but tbf they still survive it i guess they just run away
