Well, they got it completely wrong IMO which isn't hard marking just incompetence .

oh, if they give us a question where we have to write the aim, method, conclusion etc
make sure you write 'to .... blah blah blah' in the aim because a person in my class lost a mark for not writing 'to'

SOMEBODY HELP! i dont know what they mean in the dotpoint- "explain, using specific examples, the importance of correct interpretation of signals by the brain for the coordination of animal behaviour" ------------WHOEVER DOES COMMUNICATION PLS HELP ME OUT!!! THANKS

 

[ALGALELE]

lol location- the place with the arabs??
lol.......dnt tell me you live in bankstown too

This one is pretty self explanatory , basically, just talk about the activity/function of the brain and nerves being necessary for the 'co-ordination of animal behaviour'

e.g the Cerebellum controls precise muscle movements, if this area of the brain does not interpret nerve signals correctly (e.g by Damaged nerves or by being damaged itself e.g tumor) then brain will not be able to co-ordinate muscle movement properly (or at all) - You can apply this to anything, talk about Eyes and the Optic Nerve/photoreceptors/visual association/perception areas or the Ear and hair cells/auditory association/perception areas.

haha umm no not in the suburb itself. PM back, u probably know my bf.

whenever i think of the immune response i have a mental picture of little cell things in armies divided into classes. i guess it could be a way to actually get the whole idea, but putting little faces of cells to their name.
ok that was lame.

in success one, they add how animals should correctly interpret mating signals or their species will die out

touch and stuff or they might think the other animal wants to fight, lol

there are more, but i forget

thats cute

I think of a videogame, because my bio teacher found some article in time years ago where they explain the immune system as a videogame

For the syllabus point: Explian why processes of diffusion and osmosis are inadequate in removing dissolved nitrogenous wastes in some organisms.

is it because: diffusion is a slow process and osmosis is the movement of water so wastes would stay in the body? are there any other reasons ? i don't get it.

 

[dolbinau]

In the microbes experiment. What is that thing called that we sterilise in the bunsen burner and swipe the food on the agar plate with?

err.. tweezers?

haha i had a mental blank in the trial on the name of the tools we had to use to dissect the sheeps brain. instead of scalpel i put metal tools LOL

Also, diffusion only occurs when the concentration of nitrogenous wastes is greater in the blood than in the tubule, so would only occur until concentrations equal each other and not remove all of the the wastes

my teacher called it an inoculating loop, but maybe we used something different to you

do we need to know this for antibodies? ( from resource notes on site)

§ Antibodies inactivate/destroy antigens in 4 ways:
Ø Neutralisation: They can stick to the binding sites of viruses, or disable bacterial toxins by coating them. These are then engulfed by phagocytes.
Ø Agglutination: Antibodies ‘clump’ together solid antigens such as bacteria, combining many bacteria into a solid mass. This mass is then engulfed.
Ø Precipitation: Soluble antigens are stuck together by multiple antibodies, and are precipitated out of the solute (plasma). Phagocytosis follow.
Ø Complement Activation: The antibodies can stick to the surfaces of bacterial cells, acting as tags for destruction by complement proteins.​
