We measure toxicity by the dose at which adverse effects are produced. an important similarity between a sub-lethal dose and a lethal dose is:

An important similarity between a sub-lethal dose and a lethal dose is, they both produce adverse affect to which the dose is applied.

So, lethal dose causes an organism to die while in the sub-lethal, the dose is not quite enough to cause death.

True! is the answer hope this
