Some plants also produce heat in open flowers, Dr. Pell added, probably to release essential oils — "thus spreading their scent and attracting more pollinators".
The food chain ends when the last link dies and is attacked by various bacteria and fungi, the decomposers that break down dead organic matter and thereby release essential nutrients back into the environment.
Review: Society's Breakthrough -Releasing Essential Wisdom and Virtue in All the People.
They result both from the degradation of the mineral parent rock releasing essential nutrients for life, and the accumulation of dead organic matter.
Thymopoiesis requires thymocyte-stroma interactions and proteases that promote cell migration by degrading extracellular matrix and releasing essential cytokines and chemokines.
In turn, the osteoclasts, during resorption, release essential growth factors trapped in bone.
In our system, partner cells released essential metabolites for cooperators and cheaters, and cooperators reciprocated with a different essential metabolite while cheaters did not.
Decrease in GABAergic and increase in glutamatergic tone in the hypothalamus are critical for initiating GnRH release, essential for puberty (31, 32).
In cardiac cells, mitochondrial Ca2+ uptake secondary to SR Ca2+ release, essential for short and long-term metabolic adaptations, gives rise to locally restricted high calcium cell domains.
This suggests a dopamine 'overdose' effect when tested on medication, and supports the proposal that tonic increase of dopamine with dopaminergic medication masks phasic changes in dopamine release essential for classification learning (Jahanshahi et al., 2010; Shohamy et al., 2006; Shohamy et al., 2008).
