Reply to comment by CrustalTrudger in With the extraordinary amount of precipitation that has fallen on California, would that weight have any effect on the tectonic plates/fault lines and could it cause a major earthquake? by barfly2780
I love when an expert replies in such clear understandable detail. Thank you.

Only the outer core is liquid.

You are correct. It is absolutely against common medical teaching and 99% of prehospital protocols to put glucose paste or anything else in the mouth of an unconcious diabetic. Altered LOC, sure, but not unconcious.
I'm sure you also know as a nurse that it would be absolutely a bad idea to start administration of sugar or insulin prior to obtaining blood glucose.

>Sure, but as a first aider, you're not typically trained to use it. I mean, it's not rocket science, but (IANAL, just someone who has taken a lot of first aid courses) Good Samaritan laws only tend to protect you within the scope of your training, and for anything you do outside of that training (like taking even a tiny blood sample), you can be held liable for if things go wrong.
It's more in scope than administration of sugars or insulin to a diabetic, which is typically a medic though sometimes an EMT skill.
Ting a first aid course or being first aid certified doesn't even include a scope of practice anyways.
>Of course, if the 911 operator instructs you to, that's fine (at that point, you're acting under their authority, rather than your own as a first aider), but it's not something I'd recommend taking initiative on.
Again, you can get someone killed by administration of sugar or insulin, and administration of sugar or insulin is beyond first aiders/Emr anyways.
Unlike using insulin or sugar, using a glucometer poses 0 risk to the patient unless you somehow manage to miss the finger and poke them in the eye or something.
>I was taught this is the only exception to that rule; a small amount of sugary gel (e.g. honey or icing), deposited in the cheek.
Big no no. Absolutely do not do this and this hasn't been recommended for like over 20 years, at least in the USA. An unconcious diabetic needs a line, not stuff put in their mouth.

I think that's because they are very rare and there isn't a lot of them

> the core is predominantly iron with a small amount of nickel (constrained to being around 5%)
What is the constraint?

Reply to comment by simple_mech in Do insects have "meat" like other animals? I know that grubs, mealworms, etc. are eaten in some parts of the world, but if, for instance, beetles were the size of cows, could you butcher one and make beetle steak? by 9RFCat9
In the UK you can buy them in Selfridges food court. There's one in London and Brum.
You can buy scorpion lollies and meal worn snacks too. đ
You may find some online outside the UK.

Since the core is liquid, do the other elements have to form an alloy? Could they just be floating around in there?

>Actually, no.
But the four densest elementsâosmium, iridium, platinum, and rheniumâare all in fact highly siderophilic. So wouldnât we still expect a high concentration of those to be found at the very center of the inner core?

Reply to Do whales and sharks etc. have any sense of their location in the ocean, or do they live a life simply âlost at seaâ? by Legitimate-BurnerAcc
Like many other animals that travel large distances, they rely on sensing the earthâs magnetic field. The exact mechanism is still not known, but some preliminary studies in humans have shown that we also react to magnetic fields with changing brain waves, and itâs thought that these animals have a more advanced version. This is why magnets are used as a form of shark repellant.

Reply to Is it possible to tell which parent a somatic chromosome came from without testing the parents? by WillMammoth
>if any epigenetic chromosomal markings are more associated with one sex or anything like that.
Yes, this is the main thing that separates animals like ligers (M lion/F tiger) and tions (F lion/M tiger) as well as mules(M donkey/F horse) and hinnies(F donkey/M horse). Biologists wondered for a long time why these hybrids were so different depending on the sex of their parents, with the only significant, apparent factor being different womb environments. As it turns out the epigenetics differ depending on sex, which significantly effects the development of offspring even if the genes they received from their parents were the same.

Side question: Does the inner core functionally do anything?
