Indeed, in the young specimens the expression pattern of all tested molecules appears concentrated at the gut level, whereas in adult the gut loses its key role that is mostly supported by skin.
In S1/S2 segments both molecules exhibited the fine thread-like labeling near apical cell surface and in the S3 segment the labeling of both molecules was concentrated at the lateral cell-cell contacts.
According to models proposed by Alley et al. [32] and Mukhopadhyay et al. [33], lipids with relatively unsaturated tails, which create intrinsic curvature of the molecules, tend to concentrated at the poles or apical terminuses of a rod-like bacterial cell to maintain the lowest free energy on the high curvature surfaces.
In this case, the lysine or glutamine residues of these regions are cross-linked with extracellular-matrix proteins by the action of transglutaminases, which helps trappin molecules to become concentrated at the site of action [ 2- 4].
Regarding question pair 5 and 6, illustrating misconception 1 (Table 3), more than 50% of all students (including upper-division biology majors) in most semesters indicated that if a small amount of salt is added to a large volume of water and then allowed to sit still for several days, salt molecules would be concentrated at the bottom of the container.
In most cells, RNA molecules concentrate into aggregates called RNA granules.
Throughout Germany, up to 600,000 metric tons of ammonia — a nitrogen molecule concentrated in liquid manure from animal farming — finds its way into streams and lakes each year, according to Ulrich Irmer, head of water policy at Germany's Environmental Protection Agency.
For example, and concentrated at 80°C and concentrated at 80°C.
Intuition might tell us that odor molecules move in clouds, which are most concentrated at the source and disperse as they move away.
