The correct answer is E) a poison produced by an organism.
To determine the correct answer, we can break down the definitions and see which one best fits the term "toxin."
A) A worm-like amphibian that burrows in the soil: This definition does not align with the term "toxin." A toxin is a substance or poison produced by an organism, whereas this definition describes a specific type of organism.
B) A change in physical form and structure due to maturity: This definition refers to the process of metamorphosis or growth, which does not relate to the term "toxin."
C) A juvenile form of an animal: This definition refers to the early stage of an animal's life, which is unrelated to the concept of a toxin.
D) To produce and give off a substance: While this definition relates to the concept of producing a substance, it does not specify that the substance is poisonous, as implied by the term "toxin."
E) A poison produced by an organism: This definition accurately describes what a toxin is – a poisonous substance produced by an organism.
Therefore, the correct answer is E) a poison produced by an organism.
