I did hemophilia, 4got 2 mention its non curable but did mention heaps of treatments... It was a good question.

Again, no one is doubting the facts within the question, it's the ambiguity of an observation that is the underlying factor as to which is the correct answer.

Meaning that the ectotherm increases with amient temperature. As the animal is in a cage it cannot regulate its body temp by burring or finding shade ect. It's temp will then have to increase with the temp of the cage. So for an organism to have a lower temperature it must be regulating it its self.

I don't doubt the well researched facts you presented that should be common knowledge to everyone in the biology course. My arguement is in the wording of the question as both C, D are factually correct.

In saying this i am only giving my opinion like the rest of you. I do not know the answer 100%. You need to put it in the context of the question wether the answer is factual or not, distracters usually have basis of fact in the question but they do not address the question. Which is...

Communication Bullshitted my was through the insect 1 lol... With my ear diagram after i had labeled it i put a 1,2,3,4ect at different points and described what the sound wave/energy was doing at that specific area.

Were here to help, and to argue the fuck out of question 6.

2 things wrong with that dude: 1. As to my understanding, memory T cells arnt "produced" by the inflammation response. 2. "...that provide a limited response if infected by the polio virus" is wrong as vaccinations increase the secondary immune response. Answer C

The reason most people picked D is because it fit the exact model of an ectotherm increasing with ambient temperature (the temp in the cage). But, im gona stick with my answer, C, i spent a while on this question and decided the even though it is completely correct to OBSERVE the temperature of...

Just to clear this up, the dot point said show why the processes of osmosis and diffusion are inadequate in removing dissovled nitrougenous wastes. Therefore, yes some nitrogenous wastes could diffuse out but overall the reasons above are why it is 'just not good enough' at removing them.

Anyway guys i probabley wont get on here again before tomorrow so best of luck to you all. I look forward to seeing some band 6's in this bunch, I'm praying for one myself lol... Study hard, best of luck. Cheers.

Osmosis: (Like you said) It is the movement of water along a concentration gradiant. It's only water moving. Diffusion: Is too slow (^^^) BUT is also non selective of solutes. Meaning it will not deal directly with nitrogenous wastes and they need to be removed to maintain celluar functions.

It might also be good to add the vibrations of the vocals cords as air passes over them are only slight and need amplification. The nasal passageways, palate (check spelling), mouth ect amplify these tiny vibrations.

As has already been stated, the Threshold is the minimum stimuli required to produce an action potential. This process is usually refered to a an "all or none" respone as the threshold is either reached or isn't. Depolarisation of the neurons membrane causes this action potential. Migration of...

ABG (Arterial Blood Gas analysis): Specifically used to measure the the amounts of oxygen and carbon dioxide in blood (pH). In is an invasive technique requiring a blood sample. It is used to distinguish between diseases with similar symptoms. Pulse Oximetry: Measures the oxygen carring...

Communication right here!

Danz smashed this question a while back so ill just back hand it your way. [COLOR=black]

1/9 Very small class :S

Beaten!

Hybridisation occurs when two different types of organisms of the same species are bred, usually true breeding, to produce a hybred organism with desirable characteristics. An example of this is hybrid corn which has enhanced disease resistance, able to respond better to environmental changes...
