I have a question regarding the immune responses to the pathogen plasmodium that causes malaria, both innate and adaptive.

What would be the first, second and third lines of defence against plasmodium?

How many homeostatic processes do we need to know? The syllabus says glucose and temperature which I have already done, however my school is doing homeostasis for water balance where we go in depth into kidney function along with a kidney dissection. Is this really needed for HSC and am I better of not bothering about this as I have already done temperature and glucose in my own time?

I had a look at your study design for bio from NESA, they said “including but not limited to glucose and temperature” so including osmoregulation is technically allowed. In Victoria where I completed the VCE, VCAA (our version of your NESA) expects you to know only 3 mechanisms, glucose, temperature and osomoregulation.

Use a ruler, it seems that 5 stoma fit into the FOV, so the FOV size is 250 um or 0.25 mm

For the 2nd question, you'll find using a ruler that the image has been enlarged 2.5 times. You originally had 20*10= 200x magnification, so you'll need something that gives you a grand total of 500x magnification. 20x ocular and 25x objective fits this description

I am coming up to my trials and HSC and am finding it very difficult to study for biology in particular, does anyone have any advice, tips or tricks that helped them?
