What did everyone put for the why the yak has high breathing rate question

yk for the question that was like why was there actually a lower number of deaths compared to what was recorded wth were u supposed to write?

i put just because someone has tb doesnt mean they died from the tb it couldve beenn another cause of death

I said something about how they need to ventilate more to associate to oxygen so they breathe more as they live in low ppo2 environment so maximise oxygen absorbtion

it was such a random question not even related to the content at all

I put misdiagnosis

How many genes did people say were needed for heamoglobin that was so random and I had no idea. Also, the one about the type 1 diabetes I said that if the blood has high glucose then no concentration gradient will be made so glucose won't move out of PCT to blood so more in urea?

For the one about why does the injection have to go into the epidermis what did people say and also about the how would an immune response activate. I said that it has to go beyond epidermis to be able to be absorbed into the blood stream to create immune response and it would just cause the skin to swell if it didn't go beyond. Then said that the antigen presentation on B-lymphocyte causes clonal expansion of B-cells into antibody secreting plasma cells and memory cells. Anyone else??

for the injection i just put it needed to reach the blood stream where the immune system is, for the immune response i put apcs cause b cells to turn into plasma cells, which release antibodies and said it was artificial and active immmunity

What did people put as the 3 structures on the first page??

Podocyte, I think the structure was glomerulus and then can't remember the last one.

I put that you can see the servity of the disease if put per 100000 and how in smaller populations having less deaths may seem good but compared to the population it doesn’t show the true spread of the disease. Honestly a complete guess I’m prob wrong anyways(realised I answered the question just before the one ur asking about)

i put the same. for the other structure i had no idea so guessed capillary

Podocyte, I think the structure was glomerulus and then can't remember the last one.

I can’t remember what order but I got podocyte bowman’s capsule and proximal convulted tubule
