In poetry, a stanza is a division of four or more lines having a fixed length, meter or rhyming scheme. Stanzas in poetry are similar to paragraphs in prose. Both stanzas and paragraphs include connected thoughts and are set off by a space. The number of lines varies in different kinds of stanzas but it is uncommon for a stanza to have more than twelve lines. The pattern of a stanza is determined by the number of feet in each line and by its metrical or rhyming scheme.
BIOLOGICAL TOXINS. Toxins are defined as any toxic substance of natural origin produced by an animal, plant, or microbe. They are different from chemical agents such as VX, cyanide, or mustard in that they are not man-made.
Research suggests that the frog eats insects that carry the poison, and that these insects get their poison from plants. Poison dart frog. Via The Nature Conservancy/Sergio Pucci. According to Oxford Dictionaries, âpoisonous organismsâ can be defined rather simply: An organism that produces toxins that are harmful when the animal or plant is touched or eaten. Notably, there are creatures that are poisonous and venomous. And as a final point in the discussion of poison and venom, there is a difference between talking about âpoisonous creaturesâ and âpoisons.â âPoisonâ actually has a rather broad definition; it is simply any chemical substance that causes a biological disturbance in other organisms. So What Are Toxins? Unlike venom and poison, the word âtoxinâ is not defined by a specific method of delivery. Rather, a toxin has a broader meaning. It is a biologically produced chemical substance that impacts biological functions in other organisms. In this respect, anything that is synthesized (by humanity or other intelligent life) is not considered a toxin. Rather, a âtoxicantâ is a chemical substance that is synthesized/produced by human activity. In short, toxins and toxicants are narrower definitions for the word âpoison.â. So to sum: Poisons are any chemical substances that impact biological functions in other organisms.
