What tech companies did you work for? My stock options never came close to 25% of my base salary.

There are actually a few different mechanisms for a trait to be dominant vs recessive.
When an allele causes loss of function of the protein it makes, that’s often a sign that it will be recessive. For example, brown eyes are dominant to blue eyes, because the allele for brown eyes makes a brown pigment in the iris of your eye, while the blue allele simply doesn’t make the brown pigment (there isn’t a blue pigment, blue eye colour comes from the structure of the eye and the blood vessels running through it, like the veins of a pale skinned person). In this case, the recessive blue phenotype is simply an absence of pigment, so it can easily be masked by one copy of the brown allele, making the pigment. You’d need two blue alleles to have blue eyes, but one brown allele will do.
Other times, it’s a bit more complicated. For some genes, “dose” or number of copies is important, making an allele that has a product effectively recessive to the loss-of-function mutation because not enough of the product can be made from only one copy. There are also cases of codominance and incomplete dominance.

In case anyone wants to learn more about the “correct” adjective order (which most native English speakers use reflexively), this Grammarly write up explains it pretty clearly

Normally your brain and nervous-system activate your muscles.
External sources of electricity also will activate your muscles, even if your brain doesn't want to.
Generally the electricity tends to 'tell' all your muscles to tense up.
Your 'close hand' muscles are stronger than your 'open hand' muscles, so they'll win this fight and 'succeed' in closing your hand.
Your brain has no say, really, because any orders it gives are overpowered by the external source of electricity.

That's because it's not an explanation. It's conjecture based upon the assumption that buy backs only occur when a company has excess cash that they "don't even know what to do with". Buy backs are simply a financial tool and like any tool they can be used properly or improperly.

You might be a little confused. SS is a retiree payment scheme generally dependent on AGE. It is NOT payment because you are unemployed. There are some unemployment programs but nothing as significant as the SS program and targeted at poverty more than anything else.

If you ever learn a foreign language, this is an example of grammatical case, which English usually doesn't mark (pronouns are the exception to that rule), but which a lot of other languages do on all nouns.

I remember you could put your head next to the port and hear the very low audio coming out of the arm. The tubes just amplified it to your ear.

Reply to comment by dmazzoni in ELI5 How Uber/Doordash show tips on the Deliverer's app - and can they redesign the app to "hide" the tips? by [deleted]
I'm sure your restaurant is thriving. While working as a delivery driver, the restaurant owners and managers I talked to none liked the delivery apps. Some used it because they didn't have delivery otherwise but it dropped their margins to 2% or worse. Others used the delivery services because they saw a drop in orders to Skip and Uber Eats. They couldn't drop in house delivery or they would lose call in and direct orders that earned more. Now they had 3 competing delivery services and Skip and Uber out bid them for online advertising for their own restaurants.
But the next time I talk to them I'll pass on your advice. I'm certain raising prices or charging for delivery has never occurred to them.

Strictly speaking yes, since "Joe and I" is the subject of the verb "went", "I" is correct (and English word order demands "Joe and I" and not "I and Joe").
"Me and Joe" is still very common in casual English speech, though.

Bomber pilots would close one eye during the explosion so that they could maintain "night vision". I use the same strategy if i need to pee at 3am

> After how long, would you say? Weeks, months, years?
Well, empirically, I notice it after a few weeks and have mostly reset after a few months, but this is deeper than my knowledge goes. (The rates probably vary by a lot of factors, like sex and age among others.)

I can imagine it would be much more risky from a liability standpoint to have a spoilage-based date on foods.

They are usually too shocked to do anything.
Esentially all signals in your brain and muscles are due to electricity. This much triggers them all and causes them to contract.

And does that mean that if your RHR stays the same around 60ish, you're getting adequate cardio in to avoid deconditioning?

At its core, genes & DNA are blueprints for the assembly of proteins. Some proteins (often catalysts) are significant enough that their presence/absence will have an effect on the phenotype. Whether you have 1 or 2 working copies of those blueprints, they're enough to cause this dominance effect.
Keep in mind that most genetics is a bit more involved than 1 pair of genes broken down into binary pairs, but that's the brief mechanism
