the membrane receptors are activated when a certain chemical attaches itself to the receptor.
The right increasing order is Liquid, gas, plasma (the last option).
The bodies, depending on the temperature and pressure conditions, can be in the form of liquid, gas or solid. The liquid form corresponds to a form of less energy than the gas (the kinetic energy of the molecules of a liquid is insufficient to break the forces which materialize by the surface tension) but of energy superior to the solid form (contrary to the solid, the kinetic energy of the molecules is enough to make them move spontaneously relative to each other).
A plasma is a phase of matter made up of charged particles, ions and electrons. It possesses a kinetic energy superior to that of gases.
Yes the spongy mesophyll found in upper layer but in some hydrophytes maybe opposite could be possible !!!
<span>alpha subunits bind to K+ channels, close them, leading to depolarization.</span>
