Bananas and grapes produce very few to no seeds at all. The specific example I gave, Round-up Ready soy beans, are seeds that grow plants that grow seeds that DON'T grow plants. In other words, you have to buy seeds from Monstanto every time you re-plant.

Brain dead is dead. No brain activity.

Coma is a deep state of unconsciousness. People will not react to painful stimuli, etc. They are not dead and there is minimal brain activity. They may or may not recover from being in a coma.

A stroke (in the brain) is a failure of the circulatory system to provide oxygen to the brain. It can be caused by either a blockage (ischemic) or bleeding (hemorrhagic). Without oxygen, the brain tissue will begin to die. Depending upon severity and speed of intervention, a stroke can lead to minimal repercussions all they way up to coma or death.

Think Bubble Wrap, but with water instead of air.

Bubble wrap is probably 50% air by mass (though you can't feel it because air is weightless in air) and like 75-90% air by volume... but you can't just waft it around like 'normal air' because the plastic gives it structure.

To address OP's specific question about SSRIs: One of the objective findings in people with depression is decreased REM latency (so you fall into REM faster), and increased total REM sleep. There can, of course, be other sleep disturbances such as insomnia or hypersomnia. But, all things being equal, a depressed person will spend more time in REM and less time in Stages 1-3.

All that is to say, decreased REM sleep from SSRI use may actually be normalizing your sleep cycles, rather than "disrupting" them. I'm not familiar enough with the literature to say that for certain, though.

A stroke is when a blood clot (scab) blocks some blood flow in your brain; it starves the blocked area of blood and you get local damage/death of cells, but it's not big enough to take out your whole brain (usually). The rest of the brain keeps working.

Coma is when you're unconscious and won't wake up. That may or may not involve brain death. You can still have brain activity while in a coma.

Brain death is when "all" the electrical activity of the brain quits. The parts of the brain that matter to think are dead.

No, selective breeding does not count. GMOs are above and beyond selective breeding, we're talking about "completely immune to glyphosate and unable to produce fertile seeds" levels of modification. These modifications are made by literal gene edition.

The term’s a bit loose. Taken literally it applies to pretty much every crop we grow today, as you said. When it shows up in public discourse though people generally mean a narrower definition: crops specifically modified through gene editing technology like CRISPR.

It gets talked about because people are skeptical of the safety of such methods compared to “traditional” generic modification methods like selective breeding. (Whether those fears are well-founded is a different issue.)
