There was a question on the haemoglobin where the it was the fill in the blanks then the degenerate code and non overlapping and tiller codon definitions with examples there was a question on amylase in saliva breaking down amylose and how that aids weight loss when not broken down there was a question on bacteria being replicated and saying why it aids weight loss because of a positive correlation there was a question on cystic fibrosis how the mutation in the cftr causes reduced gas exchange

Can u answer the investigation qn how did u do it and what did u get for the liquid calculation thing

Not sure was i got for the calculation kinda waffled in that but the investigation I wrote about using a large group of people so it’s repeatable and giving each group the same concentrations of drug A as a control and making sure they have the same diet and age as a control as well I said to split the groups in two to allow comparisons to be made and I then said the symptoms should be monitored over a period of time I also added a little on how inhaling the salt may help reduce symptoms.

Same but I said give them the same concern try action of salt solution instead of drug A

i answered the 6 mark investigation question using CORMMS and added details at the end such as the use of a control group

how do u guys think the grade boundaries for this jan session will be like cuz i might be wrong but i heard that jan grade boundaries are usually lower than may/june grade boundaries

Honestly they will be low I think since a lot of people had mixed feeling about the paper also does anyone know about how bacteria replicating aided weightloss

I feel like they’ll be higher than last year Jan cuz our paper was easier. That question was soooo weird but I put that in replication DNA polymerase uses ATP so more energy output or sum

Can someone please tell me if this is correct for the last six marker I wrote about the percentages of the graph about both groups I wrote about how saturated and unsaturated fats can increase the chance of atherosclerosis and atheroma and cornonay artery being blocked is this right and can reduce the risk of getting them
