Describe how increased knowledge about factors that affect toxicity, such as water hardness and complexing of metals with dissolved organic carbon (DOC), has influenced the way that the regulatory community views toxicity of metals in aquatic ecosystems.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
