Asteroids are not neay massive enough to cause the gravitational disturbances we see that indicate dark matter.

You really think Dolly Parton listens to Three 6 Mafia? I highly doubt they are on her playlist, lol. She is wholesome and kind, Three 6 is... not. I've listened to Three 6 since HS in the 90's, but it really doesn't seem like something Grandma Parton would be in to.

Reply to How come there are so many indentations on the moon that are so close to perfectly round that they look as if they could have been be man-made? by mightierthor
Just because something is round doesn't mean it is man-made. Planets are spherical or oblate spheroid and they surely aren't man-made. Man-made is not the only way to attain perfect, nearly perfect, or complex structures.
Hell, look at complex life on our planet. It is far more advanced than anything man has ever made and it is 100% natural.

I was not aware that "epinephrine lowers the body's requirement for oxygen." Do you have a source on that?

I can give you a bit of a more frank, less technical and comprehensive answer that may help. If this helps add to the other answers, great. If not, ignore me.
Adjuvants work locally as well as systemically, but not both in equal measure. They are especially active at the site of the injection. A vital part of the desired vaccine-induced immune response relies on the adjuvant and vaccine antigens being in relatively high concentrations in the same place in the body.
If you just injected a person with an adjuvant only and they already had the virus on-board, you may see a very mild increase in overall immune response in the form of a slight elevation in body temp and very, very mild systemic inflammation, but it wouldn't be nearly enough to affect the course of the infection. You would also have a local inflammatory response at the site of the injection but without the vaccine along with it, you just get a sore arm with no benefit.
The adjuvant triggers local inflammation which calls white blood cells to come running, or rolling and oozing as the case may be. These white blood cells (macrophages/dendritic cells/Antigen presenting cells) are stimulated by the adjuvant to grab the vaccine antigen particles that are highly concentrated in that area and (long story short) present those viral particles to the immune system so they can pump out new lymphocytes (another kind of white blood cell) to target and kill specifically the strain of virus that was in the vaccine.
I don't know if that clarifies or obfuscates things!
Edit: typos, clarification

Reply to comment by Winnr in Can you have anemia without having low iron? by Your_Raccoon_Atheist
You failed to mention a very common cause of anemia: anemia of loss. It may be through bleeding outside the body, third spacing, or occult loss via the GI. This also results in anisocytosis and macrocytosis because larger, immature erythrocytes are pushed into the peripheral blood before they are "ready."

Your physiology still requires sunlight to activate the vitamin D. You can drink all the vitamin D fortified milk you want, but if you completely avoid sunlight, you will be deficient in the active form of vitamin D.

Reply to comment by InvincibleJellyfish in Did sheep fur always just endlessly grow or was that something that was selectively bred? Were they originally naturally adapted to be going through a lot of foliage and thickets and stuff that would keep their coat relatively trimmed? by EuroTraschBozos
Potentially, but the incredibly low cost of producing synthetics means a much, much less expensive end product. Plus, many synthetics perform better in inclement weather for numerous reasons. Synthetics are the #1 reason for the decrease in demand for wool.

Reply to comment by mosquito_christ in Has teen acne been around since prehistoric times? Did cave-dwellers have zits? Or is it related to modern eating, exercise, pollution, etc.? by Snoo-35252
Yup, it is an immune reaction to the sex hormones that causes dermal inflammation. Inflammation makes capillaries "leaky" and causes serum to ooze out of them. That serum is a perfect breeding ground for bacteria resulting in infection secondary to the immune response.

At what point does the "Sunk cost fallacy" factor in? Is it always worth getting up if we know we will just get knocked back down every time forever?
