Differential gene expression patterns allow one tissue to produce a hormone, and another to facilitate nutrient exchange. The same organ can serve both functions because it can synthesize different proteins.
<h3>Diferential gene expression</h3>
Gene expression refers to the differential process by which different genes are expressed (transcribed and then translated) in different cell types.
Gene expression enables different functions due to the production of different types of proteins which may have both enzymatic and structural functions.
A specialized cell type or organ can synthesize different proteins and also generate other molecules (either enzymes or structural proteins) due to the process of cell differentiation.

Answer:
Natural selection, the keystone of evolution, can switch direction in a matter of months, a novel experiment on lizards reveals.
Through synapses that occur in our neurons that tell our brain for our body to act in the needed way
No, because a single observation on one planet is not sufficient to discredit a theory.
There are too much variables that would cause that data, and just observing one planet is the same as ignoring all the potential variables.
