Answer:
ligand; ions; ligand; ions; nervous system
Explanation:
Ligand-gated ion channels are transmembrane protein complexes that open when they bind to their corresponding ligands (e.g., neurotransmitters). This type of receptor is known to modulate the synaptic transmission between neuron cells or neuron and muscle cells. In the nervous system, ligand-gated ion channels located at sites of synaptic contact determine the ion flow in response to neurotransmitter binding. Some examples of ligand-gated ion channels include gamma-aminobutyric acid A (GABA-A) and nicotinic cholinergic receptors.
This happened because the tall plant genotype is dominant, so if the plant has at least one tall gene, it will be tall. All the F1 generation are heterozygous with this tall dominant gene.

Sí, porque Australia es una isla separada en Oceanía, la mayor parte de Australia se encuentra en los trópicos. Australia es la parte más caliente de la tierra en el hemisferio sur, que tiene un clima desértico semidesértico. Al Norte, este, sur-este y sur-oeste semidesérticos pasan a sabanas
.dan paso a bosques de eucaliptos, palmeras. helechos arborescentes a lo largo de las orillas y en las montañas. La fauna australiana se adapta mejor a este tipo de animal.
Allí viven varios animales marsupiales (Canguro, ardilla trepadora, rata trepadora (Koala o oso australiano), ornitorrinco y animales salvajes)
