Which is most likely to change with new discoveries and technologies?

Explanation:

Whatever has been fixed after centuries of discoveries cannot be changed simply with new inventions and discoveries, and only an addition can be facilitated with the existing system, if possible.

Therefore, the taxonomical levels of the organisms will change with time, as soon as more organisms will come up into existence. Hence, the taxonomical levels would change for sure, as new inventions would come up.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
