As they do so, they will encounter a changed landscape.
Mycobacteria encounter a changed physical environment in the confined space of granulomas with a paucity of life-sustaining constituents like nutrients, oxygen and iron [ 23, 24].
This is more probable as the solubility of Ca2+ encounters a change of phase from a pH ≥ 8.2.
Therefore, while the system is insensitive to fluctuations in gene configurations in a fixed external environment, it can move to quite a different attractor when it encounters a change in environment.
Microbial communities in natural environments almost always encounter a wide variety of environmental changes (or 'disturbances,' in the field of ecology) in physical, chemical, and biological factors.
While binding with cVA, the OBP LUSH encounters a conformational change and the LUSH/cVA complex would be the active form that interacts with the receptor (Laughlin et al., 2008).

As the specific conditions of places change, we encounter a different approach to the way the archaeological project is understood.
If you ever encounter a "Whoops" moment, apologize and change the subject.
Some of the scientific and technical challenges encountered included a change in the repository design from in-floor emplacement with small packages to in-drift emplacement with large packages without backfill.
