How to convert cell units (c.u.) to mole?

If one has values in terms of cell units (c.u.) how may it be converted to $\mu$M? Should I think a "cell unit" as $1\;c.u.= \frac{1}{\text{cell volume}}$ and $1\;c.u.=\frac{1}{\text{cell volume}}*(\text{volume of 1 mole of in 1 atm)} \; Mole$? Thank you.

What is the chemical structure of neca?

I heard in the YouTube video https://www.youtube.com/watch?v=m07OvPEoR6g that pearls are made from neca. What actually is the chemical structure of neca? I can’t figure out an algorithm for determining in advance given what the answer is whether or not it will satisfy me. Sometimes when somebody is working on something, they don’t propose a concrete […]

If silver nanoparticles kill bacteria by penetrating the cell membrane, why don’t they also kill human cells on contact?

Apparently, the silver from the nanoparticles can penetrate the cell wall of bacteria and kill them from the inside. Why, then, doesn’t the same happen to human cells, e.g. the skin on my foot when I wear nanosilver-coated antibacterial socks, or the stomach lining when people drink nanosilver-treated water? Is it because the cell wall […]

What made this, is it an egg sac?

Found this "egg ball" on a gate near a greenbelt north of Seattle, WA. From other posts here, it looks similar to snail eggs, but they do not have the webbing. Two days later I went back out to measure it, but it was gone. Maybe hatched or eaten? s://i.stack.imgur.com/tj6gT.jpg

Why does high blood pressure not damage the body during exercise?

Exercise is commonly understood to lower blood pressure by making the heart stronger. Mayo Clinic says, Regular physical activity makes your heart stronger. A stronger heart can pump more blood with less effort. If your heart can work less to pump, the force on your arteries decreases, lowering your blood pressure. While exercising, though, systolic […]

Would tinnitus be explained by perpetually-bent/opened hairs in the cochlea?

When I look around for what causes tinnitus and the like, the usual response is "Well, loud sounds and hearing damage" but I feel like that’s a little plain and I am curious about the underlying mechanism / explanation on a physiological level. My previous understanding of how the ear works can be found in […]

Do animal muscles atrophy slower than humans?

Suppose I consider the silver back gorilla as an example. I cannot imagine ever seeing one in the wild intentionally doing something akin to weightlifting like humans solely for the purpose of getting stronger (if I’m wrong about this, that would be fascinating to know as well). However, last I checked a male silver back […]

Can a silhouette of a hand be determined right or left?

Not sure if this is the right stack community for this question but il ask it anyway. Just through any "biological" features can you tell if this hand is a right-hand palm down or a left-hand palm up?
