By the way, this sounds a lot like a homework question and there is a tag for that here.

comment What are the disadvantages of forbidding flights to and from the African Ebola region?
Having them separated at the airport only gives you better options in separating out passengers that started showing symptoms while on board. Infected passengers without symptoms could still change to another plane afterwards, that will not be tracked as it did not depart directly from the Ebola region.

comment True or False: Vaccines are designed to protect against invaders that are encountered rarely, not all the time
I think the idea behind this is not the frequency of the pathogen itself, but the frequency of exposure. If I am exposed to a pathogen frequently anyway, I have a chance to naturally develop immunity. If I never am exposed to it, one single exposure might be dangerous, if I am not vaccinated (exposed artificially). (Just to add, this is not necessarily true, but I tried to imagine what the author might have wanted to say.)

comment force required to do damage to child's leg/feet in collision
You should also take in account that it is a toy. Even if a collision does not damage the child, it might still scare it. Which is reason enough to avoid collisions.

comment What is this fuzzy, black fungus that grew on my plates in the 4⁰C room?
I am far from an expert, but looking at similar pictures around the net I would guess for some Cladosporium species.

comment Why are human children more likely to get lice (nits) than adults?
Additionally, adults get aware of the lice earlier and will then (hopefully) avoid close contact with others until it is cured.
