Verified step by step guidance

Understand the nature of water-soluble hormones: These hormones are typically polar and hydrophilic, meaning they can interact well with water molecules.
Consider the composition of blood plasma: Blood plasma is primarily composed of water, making it an ideal medium for water-soluble substances to dissolve.
Evaluate how substances travel in the bloodstream: Water-soluble hormones can travel freely in the plasma because they dissolve directly in the aqueous environment.
Compare with other transport methods: Unlike lipid-soluble hormones, which often require carrier proteins, water-soluble hormones do not need to bind to plasma proteins for transport.
Conclude the most likely method of transport: Given their solubility in water, water-soluble hormones are typically dissolved directly in the plasma as they travel through the bloodstream.
