currysauce, yes, some of their morphological structure help them to survive in extreme conditions. Some extremophiles are halophiles, thermophiles, hyperthermophiles, psychophiles etc.

xiao, you are on the right track. Look at the metabolism of prokaryotes! They can occupy both aerobic and anaerobic conditions! This can help them to survive in a variety of environment! So how do they do it?

For those who are interested in Microbiology: What make prokaryotes special in that they can occupy everywhere on Earth, e.g, hot spring, deep in the ocean floor, in Antarctic ice, compared to eukaryotes which can only occupy in a relatively limited environmental niche?

Sterile techniques also involve dry heat, moist heat (autoclave), chemicals, gamma and UV irradiation to kill all living matter on a particular object.

You have to know what components of fermentation are involved. e.g. yeast, water, the substrates. The main types of fermentation are alcoholic fermentation and lactic acid fermentation, each with different end product produced. You control is simply following the original fermentative...

I don't know where they came from. A friend of mine sent them to me. I guess she uses carefree then. :D

I had this sort of thread every year and I think it's fun to do it again this year. So, did you know... - A cough releases an explosive charge of air that moves at speeds of up to 100kph - Bulletproof vests, fire escapes, laser printers and windshield wipers were all invented by women...

Yes. Listen to someone that keep getting 99s. *coughs* :D

Rf value is the ratio of the distance travelled by the solute, in this case plant pigments, to the distance travelled by the solvent. Depending on whether your solvent system is hydrophobic or hydrophilic, the Rf value will mean different things. So, say you've used n-butanbol:acetic acid:water...

Electrophoresis: technique for separating proteins or nucleic acid fragments on the basis of their net charge and mass, by migrationon through paper, or through a gel (gel electrophoresis).

I think they have to sing "Inside Your Heaven" AND ONE other "Idol songs". And may be she wanted to be different from Bo by not singing "One Long Road" (or something). I am pissed at chanel 10 for cutting out so much. The final performance show and the Result finale are meant to be 1 and 2...

Congratulation to Carrie Underwood Carrie sang "Angel Brought Me Here" better than Guy did :D I think the winner's single "Inside Your Heaven" suited Carrie's voice better. And the Kodak Theatre beats the Opera House anyday :D :D

A new rule has now being introduced! The biological word MUST be related specifically to the HSC syllabus in terms of vocabulary. Water, Kangaroo, etc. are not good enough! , The purposes of this game is to learn and have fun. Personally I don't think you are learning by posting words such as...

gee.. i'll have to save this game again... Yolk - nutrient material which nourishes the developing embryo.

You don't need a D average because your UAI was high enough to gain entry to B Sc/B Education. You can start in S2. There are some courses you can take which does not have S1 prerequisites. In maths, I'm sure you can take many second year subjects assumming you did MATH1131 and 1231 or...

Depends. If a course has large amount of people doing it, then scaling will occur if the distribution of marks do not follow the trend from previous years. Nothing to do with difficulty of the course.

I did chem last year. Organic chem was horrible. :( Bascially you can't learn everything in the last minute. To do well, START revising NOW!
