Reply to Was T. rex's skull bulletproof? by aesthetic_rex

Typical assault rifles fire fairly low power rounds, such that they can't be reliably used to hunt big game, so you could probably sell it to an audience even if you don't really know if it would actually work.

So its more about how modern soldiers are equipped with a very large number of fairly small ammunition than about properties of the skull.

Reply to What excatly is the difference between a zooid in a colonial organism and an organ in a non-colonial one? by estradas_del_paraiso

One of the main differences I know of is that zooids are capable of independent movement within the larger organism. blastogenesis or budding is an asexual reproduction process where cell division is repeated at a specific site and these buds develop into new individuals that are still connected to the parent until fully mature. Not sure if this answers your question fully.

Reply to Radon is a monatomic gas, but its decay products are solids. After a decay, what happens to the individual atoms of the daughter elements? Do they stay suspended in the atmosphere or slowly rain out? by foodtower

A single atom doesn't have a state of matter. Radon-222 decays lead to a couple of short-living (half life under an hour) nuclei in the decay chain until it becomes lead-214 lead-210 with a half life of 22 years. As bulk matter all these decay products are solid but you don't get macroscopic amounts of them. As individual atoms they can stay in the air or get captured by some liquid or solid surface - including dust particles.

An isolated lead atom in the air is just a very heavy atom that bounces around randomly just like all other atoms and molecules.
