Inside the cell, DHA is immediately reduced to ascorbic acid, which accumulates at higher than outside concentrations (Nualart et al. 2003).
This is plausible as when robustness is very high, little variation becomes exposed to selection, and when robustness is very low, the conditionally adaptive mutations cannot accumulate because they are immediately exposed to selection.
Posthatch larvae of ST II medaka were immediately observed with fluorescence-dissecting microscopy to detect accumulated nanoparticles.
Therefore, these low accumulating accessions cannot be immediately usable in South China, where the problem of heavy metal and metalloid contamination is serious.
As Figure 4 illustrates, if groundwater pumping continues, impacts to the river accumulate and cannot be immediately reversed if pumping is stopped altogether.
In winter, nutrients can accumulate as photosynthesis is limited by light, whereas they can be immediately used in summer.
When etiolated seedlings of wild type are exposed to continuous light, chlorophyll a immediately accumulates after the onset of illumination.
It is just accumulated learning.
Once the timing calibration has been completed, or sufficient energy has been accumulated, we may immediately switch to an intermittent mode.
In the current study, HSPs appeared to be substantially accumulated in cells immediately after heat stress exposure, since HSP70, HSP80 and HSP90 expression levels were found to be significantly induced, compared with control samples, as early as after 1 h of exposure to 42°C.
