Semicircular canals, filled with fluid, are involved in dynamic equilibrium. The tubes are oriented in three planes: horizontal, frontal, and sagittal. They respond to changes in the position of the head.
Temperature - Skin Receptors.
four major macromolecules are carbohydrates-Energy storage, receptors, structure of plant cell wall; proteins-Enzymes, structure, receptors, transport, and more; lipids-Membrane structure, energy storage, insulation, and nucleic acids-Information storage and transfer.
not a single structure but plenty of them; it moves and movements cost lots of energy
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
That's what distinguishes it from a less complex prokaryoitic cell.

Three movements is a typical formal structure for a baroque Concerto Grosso.

Receptors and receptor proteins
four major macromolecules are carbohydrates-Energy storage, receptors, structure of plant cell wall; proteins-Enzymes, structure, receptors, transport, and more; lipids-Membrane structure, energy storage, insulation, and nucleic acids-Information storage and transfer.
Single bonds to carbon are usually freely rotational, but double and triple bonds usually are not. Rotation can also be hindered by steric factors; the carbon-carbon single bonds in cyclopropane, for example, are not freely rotational because of the constraint of the cyclic structure.
The semicircular canals, the vestibule, and the cochlea, which are subdivisions of the bony labyrinth. Semicircular canals and the vestibule contain receptors for equilibrium and the cochlea contains receptors for hearing.
Receptors for that hormone
A ball and socket joint allows movement in all directions. This type of joint is formed when a bone with a rounded end fits into a socket-like structure of another bone, allowing for rotational as well as angular movements. Examples include the hip and shoulder joints.
Hormone receptors on cell membranes recognize a hormone's chemical structure in the endocrine system. When the hormone binds to the receptor, a cell changes its behavior.
