An archaeon in a nutrient-poor environment is most likely to use <u>facilitated diffusion</u> for nutrient uptake.
<h3>What is an archaeon?</h3>
This organism represent 1 of the 3 primary lineages of modern cellular organisms revealed by sequence analysis of highly conserved macromolecules. It is consistent with their status as a third form of life and exhibit certain characteristics of bacteria as well as some certain characteristics of eukaryotes and other characteristics unique to themselves.
These organism are thought to have diverged from bacteria because it utilizes distinct GTFs and promoters. During the time of the great divergence, the archaea utilized transcription followed by reverse transcription to synthesize DNA. Hence, the promoters for RNA synthesis initiation were also replication origins and GTFs, promoters, and RNA polymerase were even more important and central functions than they are today in archaea and bacteria.
However, when this organism is in a nutrient-poor environment, it is most likely to use facilitated diffusion for nutrient uptake.

The correct answer is a conditioned stimulus.
A conditioned stimulus (CS) refers to a previously neutral stimulus, that when repeatedly paired with an unconditioned stimulus (UCS) elicits the same response as the UCS, even in the absence of the UCS. In this example, the CS is Dr.Jones closing the classroom door, because this stimulus by itself elicits a response of anxiety in students.

The main reason for migration is mostly food: people migrate where they can produce food easily, catch it, or in modern times, to produce money to buy food.
Other reasons is conflict with other people and competition for food: people migrate in the hope that elsewhere they won't have to compete.
Finally, people might also migrate to look for a better climate (where they don't have to built very cold resistible houses for example).
