Science & Technology Quiz 2: The one with the catchy title.

[Brighteye]

Yes, a decreased PO2 is a common feature. Hypoxia doesn't actually cause the tremors directly, and there are more important causes than the indirect effects hypoxia might have.

Hypoxia can cause spontaneous firing and so on, but that's in the realm of death, not congestive heart failure, I think.

 

[Perfection]

Peeps are shakin' cuz they're nervous that they might die!

 

[Brighteye]

Well, you're getting close when you talk about nervous...

 

[GoodGame]

If nervous is the way, them my last guess is Epinephrine given to a patient to help the patient survive a hard attack might cause tremors. Not sure if epinephrine would be relased during a heart attack, but I supose a heart attack might trigger a natural adrenaline rush to release epinephrine.

 

[Brighteye]

Heart failure and heart attack aren't the same thing! Heart failure is when cardiac output drops and ejection fraction drops, often due to hypertrophy or hypertension.
The drop in pressure stimulates the baroreflexes, giving a huge increase in sympathetic nervous activity (and adrenaline release, yes). This constricts all the blood vessels, giving a correction of blood pressure, but also causes the shaking.

Open Floor - 72 hour rule

 

[Brighteye]

My questions seem to be unanswerable. Will anyone else take it on?

 

[peter grimes]

What is Wallace's Line?

 

[Ziggy Stardust]

I know that one, but I haven't got a question of my own so

 

[SS-18 ICBM]

You can declare an open floor, you know.

As for Wallace's line, it's an imaginary line delineating the boundaries of the extent of species on mainland Indochina and nearby islands and the extent of other, isolated species on isolated islands in the Indonesian archipelago and Papua New Guinea. I'm not sure if that's completely right, though.

 

[peter grimes]

SS18 ICBM is almost there. Think about why there would even be a boundary like that, and the details will move into place.

 

[Perfection]

MARSUPIALS!

 

[peter grimes]

Marsupials are indeed relelvant, but they don't explain Wallace's Line. They are one of the observations that lead to the discovery of Wallace's Line.

 

[Perfection]

Because for a hundred gajillion years the two areas evolved mostly independently of one another.

 

[GoodGame]

Is gajillion a SI unit?

 

[peter grimes]

Good enough, Perfection

I just wanted to make sure that the correct answer didn't think it was only about the marsupials, but also about the plants (and other kingdoms?) as well.

Perf is up!

 

[Perfection]

Is gajillion a SI unit?

Yes


Speaking of units...



What's a mho?

 

[Olav]

I think I've heard about that... is it the opposite of ohm? Siemens or something?

 

[Perfection]

Damn 3 minutes....

Too easy.

 

[Brighteye]

Doesn't it mean something different on the internet? My honest opinion and all that rubbish?
