Old thread, and you may not have it now, but for all those who say too slow, and their commodore could beeat it http://www.weeklytimesnow.com.au/machine/paul-pattons-eureka-is-a-rocket-ship-that-should-be-handled-with-care/news-story/8748051ccc119257746500a7a4dbb7d6 and the acceleration is over...

Suppose this is gone, because I teach it, and could use it to help many students.

If you are (and it sounds like you are) the number one student in all of your subjects then the mark is in your hand and your hand alone. If you get a 95 in the external exam, then your internal mark is 95. If you get 80, and that is the highest mark, then you have been marked too easily...

The main queries on this site are: 1 Cytotoxic T-cells vs Killer T-cells. Many are relying on wikepedia, however I may suggest that Cardiff university may give a more VALID response http://www.tcells.org/scientific/ clearly they are the one and the same thing, although the more commonly known...

For all intents and purposes independant assortment and random segragation will really mean the same thing at year 12 level. You will get full marks if you use either term in a question asking about what increases the chances of genetic variation via sexual reproduction (meiosis). Don't panic...

Ahh, but if the sugars are the smaller di-saccharides or monosaccharides, they are water soluble and become even smaller, and they simply diffuse through the differentially permeable mebrane (cell membrane) producing isotonic solutions between the cytoplasm and the external environment - thus...

Anything with a lot of water in its cells would work. Cucumber works a treat as would I imagine watermelon. Potato has the added advantage of having starch as its primary solute rather than a sugar. The sugar could readily diffuse out of the cells affecting/changing the osmotic pressure, but...

I guess it could be a problem if the teacher was attempting to pass off the questions as his/her original work and take the credit for it. Or if it was so as to test their ability to set questions was being. But if it was to test YOUR ability to research and DEMONSTRATE understanding of...

I have put together some resources that may be useful to you. Tell me what you think - www.freewebs.com/seniorbiology - Cheers.

enantiostasis vs homeostasis Homeostasis is usually fairly clear for most people, the organism's body adjusts factors so that the conditions of its internal environment (pH, temp, solute concentration etc ) remains within a fairly narrow range - close enough to say that it is maintained at a...

This question came from the section of the syllabus that asks you to describe current theories about processes responsible for movement blah blah, but doesn't ask to name or identify them, so you should have only been asked to explain the processes of the theories, not neccessarily remember the...

last year 8% of the state achieved a band 6, the year before it was 2% achieved a band 6.
