OKAY.

I actually found MC quite tricky after like question 10.

Wtf was with the communication question on the wavelength / sound shadow. I got 1400Hz +, what did you guys get?

I put W as the substrate, as that is what the enzyme acted upon.

Someone pretty much mentioned the 8 marker in the bio marathon thread lol how

For that i put brain. Biology so ez not even considered hsc exam.
For those that did communication, what did you do for that 4 marker on sonic shadow. I put 1400-5000hz but others put greater than 1400hz.

sonic shadow? For communication right?

Yeah sorry typo it was sound shadow! The bit of sound the ear does not receive!

Yeaaaa you're right - it was 1400-5000. I got tricked and wrote down 180-1400 Hz

Also what did everyone put for what is "X"? I put receptors in the skin as the answer.

They said core body temp though + posterior hypothalamus is responsible for initiating warm-up mechanisms [so brain]

Technically you should have said > 1400Hz or 1400Hz + since the sound shadow would be any value greater than that right up until 20,000Hz (limit of human hearing), not just up to 5000Hz.

I did 1400-5000 according to the figure, w/e but the questions in the discussion group were the same for a few of the harder q's

 

[wigglestein]

The ebola virus question was the worst, I was thinking of vaccines while the question was asking about treatment, and vaccines are a form of prevention, so confusing lol.

They treated the patient with plasma that contains immunoglobins so it would help to defeat the virus [I think]

I did antibodies + extra haemoglobins - oxygen to replace those lost by excess bleeding.

I also got stuck on this question. Could remember exactly what plasma had in it.

I was traumatised from breastfeeding in the exam - gonna appeal

 

[Flop21]

And if anyone says it was so easy and how biology is easy, then I'll be waiting on HSC result day to see your state rank.

What was the process of the model of DNA. I put dna replication but wasnt sure what it was.

Plasma doesn't contain cellular components so the extra haemoglobin/O2 wouldn't necessarily be relevant but you're right about antibodies [which is what I think they wanted in the response] + also to increase blood volume I think

SAMEEEEEEE i was getting confused as eff though wb the next question!! the epidermal hairss; got confused with that too LOL

 

[Catz]

Did anyone do genetics what was that question with gene mapping

And I found that this exam was harder then previous years

Yea I was pretty surprised when that popped up. That and the comparison of movement of sugars in human tissue and plant tissue question were similar to some in my trial exam.

Which part?

i think its meant to be greater than 1400 since at 1400 Hz you would have the wavelength = length of head which wouldn't create a sound shadow
