Hormones are specific. explain how a receptor results in the cell being able to respond to only one specific hormone.

This is because the active site of the receptors on the cell and the hormone are akin to lock and key respectively. The conformations of the receptor’s active site and the hormone allow them to interlock with specificity. The receptor (which is a transmembrane protein) is connected to second messengers inside of the cell that triggers a biochemical cascade in response to the hormone.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

i'm thinking 600 feet deep in one of the finger lakes.
