Various states of matter have molecules moving at different velocities.
<h3>Molecules in matter</h3>
Matter is composed of molecules. These molecules that compose matter are in constant random motion. The kinetic energy and velocity of the molecules depends on the state of matter.
Molecules of a gas are fastest followed by molecules in a liquid. Molecules in a solid do not move at all hence solids have a definite shape.

Relative dating concerns the dating of fossils by using stratum (layers in the rock) to find the estimated age.
Absolute dating is finding the age of a fossil by using radiometric methods, such as fluorine dating or half-life dating; which is more accurate than relative dating.
<span>siRNA guides the RISC that cleaves the target mRNA. siRNA binds to its target mRNA due to its complementarity.</span> <span>Small interfering RNA (siRNA) has a function in RNA interference, which means it causes gene silencing through repression of transcription. siRNA together with some proteins (like Argonaute) form the RISC. When siRNA recognize the target mRNA it causes degradation of mRNA and thus silencing the gene that encodes that mRNA.</span>
