Question

Which of the following statements is false? A. Hormone receptors evolved later than many of the hormones with which they now interact. B. Vertebrates and invertebrates use some of the same hormones. C. The same hormone typically plays different roles in vertebrates and invertebrates. D. Several hormones function as both hormones and neurotransmitters. E. None of the answer options is false.

Answer 1

Answer:

The correct answer is option A. "Hormone receptors evolved later than many of the hormones with which they now interact".

Explanation:

It is false to affirm that hormone receptors evolved later than many of the hormones with which they now interact. There are multiple scientific studies that support the theory that  receptors and ligands evolve at the same time  in what is known as "synchronous birth". Receptor and ligand interactions are key components in the processes of living organisms, therefore, it they should evolve together in order to be functional.
