Of the species below, only ________ is not an electrolyte.
Tems11 [23]
C- argon 
This is because, an electrolyte is a solution that conducts electricity due to the presence of ions, and since argon is an atom and not an ion, it cannot conduct. Thus, it is a non-electrolyte

At the molecular level, gene duplication often produces novelty in a lineage. This process provides another evolutionary pathway
alukav5142 [94]

Answer:

Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated  a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).

The publications above cited are the following:

J.T. Bridgham, S.M. Carroll, and J.W. Thornton (2006). Evolution of hormone-receptor complexity by molecular exploitation. Science, 312(5770), 97-101.
