The answer is it is reflected.
The correct answer is compaction and cementation.
With the build-up of the layers of sediments, the pressure on the lower layers enhances. The layers are clasped together and any water mixed in sediments is eliminated out. This procedure is known as compaction.
At the similar time, the particles of the sediment start to conglomerate with each other, and they are cemented together either by minerals or by clay like calcite or silica. After the procedure of cementation and compaction, the sequence of sedimentary has modified into a sedimentary rock.
The answer is ligand gated channels.
Ligand gated channels are also called as ionotropic receptors that open in response to the binding of specific ion, which is generally not solute. These are made up of particular set of transmembrane proteins that open and close to allow the movement of ions like K+, Na+ that passes through the plasma membrane in response to binding of the chemical messenger.
Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words,isotopes have the same atomic number because they are the sameelement but have a different atomic mass because they contain a different number of neutrons.
