Could a Weapon of Mass Destruction, targeting only humans, be developed?
Viruses are highly species-specific, i.e. a human virus will only kill humans. So a biological weapon will do the job. The best virus to use is beyond my knowledge, and I am a bit concerned a ...

Is it possible to genetically modify human lungs to breathe Martian air?
No.

Could genetically engineered horses make cavalry survivable on a battlefield with modern technology?
No
Armoured cavalry is faster than horses, carries self-propelled guns, is more capable of traversing most terrain, and offers a much higher combat value-per-unit than any animal could.

Could genetically engineered mint take over the planet?
It's not that reasonable.
For one, mint doesn't grow well everywhere. It needs plenty of water to thrive, meaning that dry or arid climates wouldn't be easy for it when compared to less needy plants.

Would human life expectancy increase by a significant amount of years if all organs had the regrow/self-repair ability that the liver does?
Most death is not from cellular wear and tear.
Joints wear out. But it is unusual for wear and tear to be a cause of death. For orientation: causes of death in the US.
