Kelly Clarkson is touring Australia! Woohoo! Too bad it's in the exam period :( I hope she will be singing on Oz Idol but I don't think she will..

Depends on what type of food poisoning you're talking about. From your list there, Staphylococcus-contaminated food is infectious. But if you use mercury or any other heavy metal food poisoning, then it is not infectious. As to how many marks you might get, it really also depends on the marks...

hmmm, if the question ask you to explain ONE, then you can just explain one (for 1 or 2 mark question). If it's a 3+ mark question, then it won't hurt to explain both. If you decided to do biochemistry at university, the current, most-up-to-date model is actually not any one of those, but...

You are correct. Veins have thinner wall, but a wider diameter in its lumen where blood flows, compared to arteries.

You don't have to. A lot of Adv science students at UNSW don't know what they want to major in until their second year. In the first year, you bascially do all the same subjects regardless of your what your major is. Then you can decide in your second year what you want to major in. The UNSW...

Why it is not consumed?? This is because enzyme is a protein and all it does is to lower the activation energy required for a reaction to occur. So in biological terms, substrates bind and fit into the enzyme active site and the enzyme convert them to products and releases them again. This...

We'd like to say good luck to all of you for the upcoming HSC exams, particularly the Society and Culture Exam. You've come so far with the PIP and trials so do your very best in your final hurdle. Mishka and I look forward to hearing some of the successful stories from you soon...

Please don't get your teminologies mixed up! If you are not sure of the differences of some of the terms, ask! You will be penalised in the HSC exam if you use the terms incorrectly! If even you wrote an outstanding response for the 6/7 marks question, you will lose marks for using an incorrect...

Remember don't get mix-up between secondary immune response and second line of defence. They are completely different and cannot be used interchangeably. Saedie, I don't think you can compare the "length" of response between 2nd and 3rd line of defence because while a 3rd line of defence is...

I think you're getting confused about how many copies of chromosomes are in a human somatic (body) cell. Remeber, a body cell has 46 chromosomes. This equates to 2 copies of EACH chrosomsome (2 times 23 = 46). In reference to your example, there are 2 copies of the same genes on chromosome...

Yep, I'll be happy if Emily win the thing. It would be cool if Emily and Anne are in the final - battle of the voices! Hope the winner's single won't be as dodgy as Listen With Your Heart.

No. not every gene has 2 copies. For example, the male has only 1 copy of the sex chromosome, therefore all the genes that are on the Y chromosome are called hemizygous. And this is true for the X chromosome in males. And I don't really get what you're trying to ask. If there is a gene on...

Yep, just tough it out. Why? 1. If you drop, you fail, might as well give it a crack! 2. You have nothing to lose! 3. And if you pass you don't have to ever do it again 4. And plus you don't want a "Fail" to appear on your record.

hmmm, what are everyone hope for when their results come out? Share your thoughts here as well :) You can always pray for a whole month before your exams for exam questions that you know the answers to. :D hmm, I know Minai's birthday wish will be along the time of HD HD HD HD :D

hahah, every year it's like that for you, your birthday in the exam perioid... haven't you got use to it already? :D

All of them sang average. Mark holden left the show. I think he was really looking forward to "the Prayer" standards but everyone under-delievered by his high standards. he got pissed and left. But I agree with him. Voters may decide for today. But in a year or two, only true stars will...

:( :(......

It's a combination of your definitions. Osmosis is a special type of difussion, and like kadlil said, the movement of water from high conc. to low conc. acorss a selectively permeable membrane.

Did any of you saw the ad for this week's show. That girl with glasses and frizzy hair, who did the flirt thing with her hair, inspired to be a paeleontologist? *shudders*
