What is 4.09784 correct to three sig figs? a) 4.09 b) 4.10 c) 4.097 d) 4.098

I'm such a fucking idiot, I put A for Question 1. So I only got 9/10. SERIOUSLY BRAIN?

2U maths, Ancient History, SORII and Chemistry.

I hate multiple choice. I prefer getting straight into it.

I defined DNA replication & Evolution. Then I went on to say that DNA replication results in identical copies of genes, also went on to say that the p53 gene always checks that the DNA is not mutated before mitosis starts. Then I talked about because DNA always replicates itself, this means that...

Re: General Thoughts: Biology Xylem consists of dead cells! So they can't have a cell wall! Pretty sure the answer was B) Phloem has a cytoplasm.

Figured I should post my answers here and not in the other thread! 1 B 2 C 3 A 4 C 5 A 6 C 7 B 8 B 9 B 10 C 11 C 12 C 13 D 14 B 15 B 16 D 17 D 18 D 19 A 20 B I only got 10/20 in the CSSA trials, bombed out massively in that. I hoping to get higher in the HSC though! Which I think I did...

Re: General Thoughts: Biology PLEASE tell me what I got in multiple choice! 1 B 2 C 3 A 4 C 5 A 6 C 7 B 8 B 9 B 10 C 11 C 12 C 13 D 14 B 15 B 16 D 17 D 18 D 19 A 20 B I only got 10/20 in the CSSA trials, bombed out massively in that. I hoping to get higher in the HSC though! Which I think I...

If it's a big question, Transposons can also impact gene expression, and subsequently (if this happens during development) can impact on morphogenesis. Don't you just absolutely love how everything ties in together in this topic?

Transposable DNA are segments of DNA that can move from one position to another on the DNA. They may be cut from one position and interested to another, subsequently causing deletion, addition or relocation of DNA bases in a neighbouring segment (frameshift basically). Basically, they impact on...

Huge ass dot point. It is a SPECIFIC immune response. Consists of antibodies, T-cells (cytotoxic, helper, supressor & memory) and B-cells (plasma & memory) T & B cells interact during this process. Look a couple pages back, @teeah explained this perfectly.

What's everyone's plan of attack tomorrow? Personally I'm going to skim through the paper for about 2mins, then spend a fair amount of time thinking about the large 7/8 markers. Then I'm going to work through the paper with those in mind, and do all those big markers last. Hopefully I can...

I'm tired actually. Probs going to get some sleep, get up around 6am and study! I'll be nervous as soon as they sit me down in that chair before starting the exam and when they read us our 'rights.'

That's a great summary & understanding in my opinion.

They could be really, and I mean REALLY mean this year. There is easily enough information on it for 5 marks.

I don't know about you guys, But I don't think a question on the historical development of understanding the cause & prevention of malaria (including naming all those people involved: laveran, golgi, manson, grassi and ross) has ever been asked in the HSC. At least not for the past couple years.

Basically it works to regulate & maintain an organisms internal environment in response to their external environment. Made up of two parts: Central nervous system (CNS) and Peripheral Nervous System (PNS) CNS: -This part acts as the control centre for all of the body's responses by...

Alright everybody, WHEN GIVEN A DIAGRAM ON THE XYLEM/PHLOEM! How do you know how to identify which is which? Eg: Phloem has sieve plates & companion cells etc. However, some pictures make it hard to identify. Could you post pictures from google or somewhere else and explain how to tell them...
