Under extreme cold, there is no development to L3 but eggs can survive for long periods to develop if conditions become favourable, while L3 survival is reduced under repeated freeze thaw cycles.
When a reservoir is flooded with polymer, the mobility ratio between the displaced fluid and the displacing fluid become favourable compared to the conventional water flooding.
When a polymer flooding is performed, the mobility ration between the displaced fluid and the displacing fluid become favourable compared to the normal water flooding, therefore, the sweep efficiency and the cumulative oil recovery is improved.
Finally their reproductive organs resume growth and development leading to blooming when temperature conditions become favourable.
Thus, if we take a given sheep population and imagine selecting for an increase in frequency of the A allele (i.e. increased resistance to worms or a reduced WEC), then worm alleles that previously had no fitness effect may become favourable and begin to increase in frequency.
FLA can survive in the cyst stage for extended periods of time, only to become active trophozoites when environmental conditions become favourable again [ 6, 10].
Under adverse environmental conditions, it has been shown to exist in a viable but non-culturable state which could revert to a transmissible state when climatic conditions become favourable, suggesting that in endemic regions, the aquatic environment may serve as a reservoir for this pathogen in the absence of an outbreak of cholera.
When conditions become favourable, S. cerevisiae is able to grow on a modest array of fermentable and non-fermentable carbon sources (mostly six-carbon sugars).
When the conditions become favourable, stored carbon reserves are usually fuelled up to support cell division and vegetative growth.
This may be due to the fact that bacteria (especially spore-forming bacteria) are capable of re-growth when conditions become favourable.
