Multipe choice has screwed me. 10/15 with what u guys are saying.

Hmm does anyone else think this?i agree that its C
because they don't know what type of disease it is therefore they cant vaccinate the healthy animals and yes its quarantine
yep.Hmm does anyone else think this?
It doesn't explicitly state they do not know what kind of disease it is and I can't see anything implicit suggesting that they do not either...
If you were to go by most correct i still think it's A, isolation + vaccine > quarantine
most people put D for 11 too, but I spent a while thinking about it in the exam and am fairly confident it is B... many will disagree but cannot support their claim further than "ye they open at midnight and not in the day because of heat duh," PM me if you want my full reasoning for it.yep.
If i said i put 4.a, 1.a and 11.d, would i be right in saying that i got 14/15 ?
Boxhunter: dw too much. I just did a pe exam today and got 20/20 for its mc. Shouldnt be to hard.
Vaccination definitely helps to stop the spread of a disease. It is a proven fact that if enough of the population is vaccinated (80% I think) then a disease won't be able to spread. This is why the government encourages immunisation so much. Sure it helps with an individual's ability to avoid the disease, and if there are enough individuals that can't get there disease then there is no medium for it to spread. So I put A.But from my understanding - I am questioning how vaccination prevents the disease from spreading? It improves the immune response of the individual, but it doesn't stop the disease spreading.
yeah i got 14 cos i got q 1 wrong.most people put D for 11 too, but I spent a while thinking about it in the exam and am fairly confident it is B... many will disagree but cannot support their claim further than "ye they open at midnight and not in the day because of heat duh," PM me if you want my full reasoning for it.
Oh and 1 is C.

1. Plants also lose water at night and respiration does not need all night to occuryeah i got 14 cos i got q 1 wrong.
I think 11 is D. Just remember, you say that plants close the stomates at night cos theres no need for CO2 (no photosynthesis) but remember that plants need oxygen as well, and might leave the stomates open for standard respiration. They might as well, cos transpiration rates will be minimal.
A disease has been identified in animals.THEY DO NOT KNOW WHT DISEASE IT IS! It is C - quarantine
Some is carbaminohaemoglobin...but small percentage. It was A. Oxygen does not bing STRONGLY to haemoglobin. The oxygen does not bind STRONGLY to the Iron containing HAEM groups on the alpha and beta chains...it does not bind strongly so the bonds can easily be broken when pH drops a tiny bit (which means carbonic acid = carbondioxide)i got the exact answers as this.
9 cannot be B as carbon dioxide is carried in blood as bicarbonate ions in plasma, not attached to haemoglobin
