Actually I think it is D now. Just because, factually it is correct. (Ectotherm metabolism increase with temperature)

Because if you say, the temp of the organism is less than the cage - how can you conclude that it's an endotherm over an ectotherm?
Well I thought that for ectotherm body temperature = cage temp.

when i read qu 6,
i pretty much eliminated A and B straight away.
D looked more correct imo as it demonstrates an ectotherm's reliability of its external temperature for its body temperature. so pretty much as the cage temp increases, it's body temperature increases. ( ectotherms usually have to physically get out of the sun to stop overheating in the day... and i doubt there is a cave in that cage)
the only thing i wasnt 100% about was the word metabolism, because its usually used when defining a endotherm, but then i realised ectotherms also have a metabolism, its just much lower rate than endotherm.

The thing is, an ectotherm couldn't possibly raise it's temperature above that of the cage's temperature (where would the heat come from?), so it's almost guarenteed to be just below the temperature of the cage.

So therefore C = incorrect. If my hypothesis is right lol.

C was for endotherm not ectotherm. If the ambient temperature was greater than the internal body temperature of the endotherm then C should be right..I think.

But D is the most correct answer.

9) What is the Role of antigens in the body's defence against disease?
A) they bind to invading pathogens
B) they trigger the immune response
C) they inactivate invading anitbodies
D) they supress the inflammation response



What's the answer to 9??


I put C, but people at the begining said it's B?

Yes, the hormones are ADH and Aldosterone. For 5 marks, you had to describe how they are used, and when they are needed.

ANTIGENS are the 'evil' guys. They are the invaders. ANTIBODIES are what are produced by B cells, thus they aren't 'invading'. :)

So the answer is B

And I'm saying that a ectotherm could also have a lower body temp than the cage, thus making its definition ambiguous.

Ah the test is over now guys. You can't change it. Let's not reflect on it too much. Move on to your next exam - and wait out til December 17, hehe.

person one cant be a carrier cause its male so the male has to be either not affected or affected ..not inbetwen

Lordie said:
The last question - I put the person 1 was a carrier, person two(the female was not affected, and person three was a carrier. I said this because it was sex linked, and the son's of the parents, some of them had it. So wasn't that B?
